6 Question · 20 marks
Question 1 · Short Answer
1 marks
An analysis of a storm hydrograph shows that the peak rainfall occurred at 14:00 hours and the peak discharge of the river was recorded at 17:45 hours. State the lag time (in hours and minutes) for this drainage basin.
Show answer & marking scheme

Worked solution

Lag time is defined as the time interval between the peak of the rainfall event and the peak discharge of the river.

$$\text{Lag Time} = \text{Time of Peak Discharge} - \text{Time of Peak Rainfall}$$
$$\text{Lag Time} = 17:45 - 14:00 = 3 \text{ hours } 45 \text{ minutes } (\text{or } 3.75 \text{ hours})$$

Marking scheme

Award [1] mark for the correct identification of the lag time:
- 3 hours 45 minutes (accept 3.75 hours or 3h 45m).
- Do not accept "3.45 hours".
Question 2 · Short Answer
1 marks
At a specific monitoring station along a river channel, the cross-sectional area is measured at \(15\text{ m}^2\) and the wetted perimeter is measured at \(7.5\text{ m}\). Calculate the hydraulic radius of the channel at this station (include units).
Show answer & marking scheme

Worked solution

The hydraulic radius (\(R\)) is a measure of channel efficiency and is calculated using the formula:

$$R = \frac{A}{P}$$

Where:
- \(A\) is the cross-sectional area of the channel (\(15\text{ m}^2\))
- \(P\) is the wetted perimeter (\(7.5\text{ m}\))

$$R = \frac{15\text{ m}^2}{7.5\text{ m}} = 2\text{ m}$$

Marking scheme

Award [1] mark for the correct calculation with appropriate units:
- 2 m (or 2 metres / meters).
- Reject "2" without units, or "2 m²".
Question 3 · Outline Features
2 marks
Outline two characteristics of a braided river channel.
Show answer & marking scheme

Worked solution

To obtain full marks, the student must outline two distinct characteristics. First, multiple interwoven channels: the river splits into several smaller, shallow channels that continuously divide and rejoin around temporary bars. Second, sediment bars or islands (eyots): these channels are separated by unstable, frequently shifting bars of gravel and sand deposited due to high bed load and fluctuating discharge.

Marking scheme

Award 1 mark for each outlined characteristic, up to a maximum of 2 marks. Award 1 mark for outlining the network of multiple, dividing, and rejoining sub-channels. Award 1 mark for outlining the presence of shifting sediment bars, islands (eyots), or high bed load deposited during periods of low discharge. Note: Do not award marks for simply naming a feature without a brief description/outline.
Question 4 · Explain
3 marks
Explain one geopolitical challenge associated with managing transboundary water resources in a drainage basin.
Show answer & marking scheme

Worked solution

An effective response should identify a specific geopolitical challenge, explain the mechanism of conflict between states, and detail the consequence for transboundary management. For example: 1. Identification (1 mark): Upstream-downstream conflict over water diversion or dam construction. 2. Explanation (1 mark): Upstream nations construct infrastructure (such as reservoirs or irrigation canals) that alters the natural flow, temperature, or sediment load of the river. 3. Consequence (1 mark): Downstream nations experience reduced water availability, impacting their agriculture, energy production, or ecological stability, which strains diplomatic relations and hinders joint basin management.

Marking scheme

Award [1 mark] for identifying a valid geopolitical challenge (e.g., upstream water diversion, lack of transboundary treaties, water quality degradation across borders). Award [1 mark] for explaining the physical or political mechanism behind the challenge (e.g., how upstream infrastructure development directly restricts downstream water access). Award [1 mark] for a detailed development showing why this complicates management (e.g., leading to legal disputes, non-cooperation, or regional instability that prevents integrated river basin management).
Question 5 · Explain
3 marks
Explain one physical challenge in managing groundwater sustainability in a rapidly expanding urban area.
Show answer & marking scheme

Worked solution

The response must explain a physical challenge linking urbanization to groundwater levels. This involves: 1. Identification (1 mark): Reduced groundwater recharge due to land-cover change (impermeable surfaces). 2. Explanation (1 mark): Urban surfaces like roads, pavements, and buildings prevent rainwater from infiltrating into the soil, routing it instead into storm drains and surface streams. 3. Consequence (1 mark): This lowers the local water table, making groundwater extraction increasingly unsustainable and potentially leading to hazards like land subsidence or saltwater intrusion in coastal areas.

Marking scheme

Award [1 mark] for identifying a valid physical challenge (e.g., reduced aquifer recharge, land subsidence, or saltwater intrusion). Award [1 mark] for explaining the process/mechanism (e.g., how paved urban surfaces prevent natural percolation and divert water to surface runoff). Award [1 mark] for explaining the direct consequence for groundwater sustainability or management (e.g., causing a drop in water tables, necessitating deeper and more expensive wells, or damaging urban infrastructure through subsidence).
Question 6 · Examine Essay
10 marks
Examine the relative success of hard engineering versus soft engineering strategies in managing river flooding.
Show answer & marking scheme

Worked solution

Introduction: Define hard engineering (structural, man-made interventions designed to disrupt natural river processes, e.g., dams, levees, and channelization) and soft engineering (environmentally sensitive, lower-cost strategies working with natural river dynamics, e.g., afforestation, wetland restoration, and floodplain zoning). State that 'success' can be evaluated based on cost, ecological sustainability, social impacts, and long-term efficacy. Body Paragraph 1: Hard Engineering. Evaluate successes: provides immediate, highly visible, and reliable protection for high-value urban areas, and can offer multi-purpose benefits like hydroelectric power. Evaluate limitations: extremely expensive to build and maintain, often transfers flood risk downstream, causes severe ecological disruption to aquatic habitats, and can fail catastrophically (the 'levee effect'). Use examples such as the Mississippi River or the Three Gorges Dam. Body Paragraph 2: Soft Engineering. Evaluate successes: highly sustainable, economically cost-effective, enhances biodiversity, and reduces flood peaks naturally. Evaluate limitations: requires vast areas of land (often impractical in highly urbanized regions), takes significant time to become fully operational (e.g., forest growth), and may fail during extreme, historically unprecedented weather events. Use examples such as the River Kissimmee restoration or UK upland afforestation. Body Paragraph 3: Synthesis/Evaluation. Explain how success is context-dependent. Urban centers require the immediate security of hard engineering, while rural catchments are ideal for soft engineering. Conclude that modern best practice has shifted toward Integrated Drainage Basin Management (IDBM), which combines both approaches (e.g., the Netherlands' 'Room for the River' scheme) to balance immediate safety with long-term ecological and economic sustainability.

Marking scheme

Level 1 (1-3 marks): Simple description of some flood management methods. Little or no distinction between hard and soft engineering. Lacks specific case studies or evaluation of 'success'. Level 2 (4-6 marks): Explains both hard and soft engineering strategies. Mentions advantages and disadvantages of each, with some generalized examples. The analysis is structured but lacks deep evaluation of 'relative' success. Level 3 (7-8 marks): Detailed examination of the relative success of both strategies. Well-structured response supported by appropriate geographical terminology and specific case study details. Evaluates success across multiple dimensions (economic, social, ecological). Level 4 (9-10 marks): A sophisticated, balanced, and highly evaluative essay. Clearly argues that 'success' is scale and context-dependent, demonstrating how modern flood management integrates both approaches (such as IDBM). Supported by precise, well-integrated case study evidence.

Question 2 · Short Answer Data Extract
1 marks
Based on the following data for peak-hour traffic congestion (extra travel time): Metro X (54%), Metro Y (35%), Metro Z (62%), and Metro W (41%), identify the metropolitan area that experienced the lowest level of traffic congestion.
Show answer & marking scheme

Worked solution

Comparing the peak-hour congestion percentages: Metro Z has the highest (62%), followed by Metro X (54%), Metro W (41%), and Metro Y has the lowest (35%). Therefore, Metro Y is the correct answer.

Marking scheme

Award 1 mark for identifying Metro Y. No other answers are acceptable.
Question 3 · Outline Economic Reason
2 marks
Outline one economic reason why retail activities have increasingly relocated from Central Business Districts (CBDs) to suburban or edge-of-town locations.
Show answer & marking scheme

Worked solution

According to bid-rent theory, land price decreases with distance from the Central Business District (CBD). Retailers relocate to the urban periphery because:

1. **Cheaper Land / Lower Rent**: Suburban land is much cheaper per square meter, which directly reduces fixed operational costs.
2. **Space for Expansion**: Lower land costs allow retailers to construct larger, single-level warehouse-style stores (e.g., hypermarkets, retail parks) and offer free parking, which is highly attractive to car-owning shoppers and financially unviable in congested, expensive CBDs.

Marking scheme

Award 1 mark for identifying a valid economic reason, and 1 mark for a developed explanation of how this drives the relocation of retail activities.

* **Valid reasons (1 mark) include:**
* Lower land values / rental costs in suburban areas.
* High cost of parking / congestion charges in the CBD.
* The need for large spaces to achieve economies of scale (which is financially unviable in the CBD).

* **Explanation / Development (1 mark):**
* ...which allows retailers to build massive retail parks with free customer parking, lowering their overheads and maximizing profit margins.
* ...which makes the CBD less financially competitive for bulk-goods retailers who require large floor areas to display stock profitably.
Question 4 · Explain Challenges
3 marks
Explain one environmental challenge associated with the rapid growth of informal settlements in urban areas.
Show answer & marking scheme

Worked solution

One major environmental challenge of rapid informal settlement growth is the degradation of local water ecosystems. Informal settlements often develop rapidly without official planning, which means they lack basic municipal services such as closed sewerage networks and waste collection. Consequently, untreated liquid waste and greywater are discharged directly into local rivers and streams. This causes severe water pollution, eutrophication, and a loss of aquatic biodiversity, while also contaminating water sources used by downstream communities.

Marking scheme

Award 1 mark for identifying a valid environmental challenge (e.g., river pollution from untreated sewage, soil degradation/landslides on steep slopes, or accumulation of uncollected solid waste). Award 1 mark for explaining the cause of this challenge in relation to informal settlements (e.g., absence of municipal sanitation planning, building on marginal or hazardous land). Award 1 mark for explaining the environmental consequence (e.g., loss of aquatic biodiversity, contamination of local aquifers, or severe soil erosion).
Question 5 · Explain Challenges
3 marks
Explain one challenge that the Urban Heat Island (UHI) effect presents for sustainable urban management.
Show answer & marking scheme

Worked solution

The Urban Heat Island (UHI) effect leads to elevated temperatures in urban cores compared to surrounding rural areas. A key challenge this presents for sustainable urban management is the dramatic increase in energy consumption for artificial cooling. During hot periods, the widespread use of air conditioning units heavily strains local power grids, increasing the risk of blackouts. Furthermore, if the electricity grid relies on fossil fuels, this surge in energy use increases greenhouse gas emissions, directly contradicting city targets for climate mitigation and sustainability.

Marking scheme

Award 1 mark for identifying a valid challenge related to the UHI effect (e.g., increased energy consumption, heat-related health risks, or elevated water consumption). Award 1 mark for explaining the mechanism behind this challenge (e.g., higher temperatures drive the continuous use of air conditioning systems, or heat waves strain vulnerable populations' health). Award 1 mark for linking the challenge directly to sustainable urban management (e.g., making it harder for cities to reach carbon-neutrality goals, or straining public healthcare budgets and municipal resources).
Question 6 · essay
10 marks
Evaluate the effectiveness of strategies designed to manage the environmental impacts of transport in one or more named urban areas.
Show answer & marking scheme

Worked solution

An outstanding response will focus on managing the environmental impacts of urban transport, such as air pollution (PM2.5, NOx), carbon emissions, noise, and visual pollution. Candidates should select one or more appropriate urban case studies. For example, Curitiba's Bus Rapid Transit (BRT) system can be evaluated: it dramatically reduced fuel consumption and air pollution by shifting commuters to public transport, though it faces challenges of capacity limits due to a growing population. Alternatively, London's Congestion Charge and Ultra Low Emission Zone (ULEZ) have successfully reduced traffic volumes and improved nitrogen dioxide levels in the city center, but have faced intense political opposition, high operational costs, and concerns regarding social equity for low-income drivers. Another strong example is Copenhagen's extensive cycling infrastructure (Bicycle Superhighways), which has successfully converted over 40 percent of commutes to bicycle trips, significantly reducing the city's carbon footprint. The evaluation should weigh the success of these measures (e.g., immediate environmental improvements) against their limitations (e.g., displacement of traffic, high capital expenditure, and political resistance) to arrive at a reasoned conclusion.

Marking scheme

Marks are awarded based on a four-level holistic rubric: Level 1 (1-3 marks): The response is mainly descriptive with little or no evaluation. It may list transport problems or generic solutions without clear link to specific urban areas. Level 2 (4-6 marks): The response describes some transport management strategies and makes an attempt at evaluating their environmental success, but lacks depth or specific details of named urban areas. Level 3 (7-8 marks): The response provides a structured evaluation of specific strategies in named urban areas, using accurate geographic terminology and showing a clear understanding of environmental outcomes and limitations. Level 4 (9-10 marks): The response offers a highly detailed, well-balanced evaluation of transport strategies. It addresses both successes and limitations, integrates sophisticated case study detail, and reaches a synthesized, well-supported conclusion.

Question 5 · short_answer
4 marks
Explain two reasons for the rapid growth of megacities in low- and middle-income nations.
Show answer & marking scheme

Worked solution

The rapid growth of megacities is driven by: 1. High rates of rural-to-urban migration, where push factors (such as agricultural mechanization or extreme weather events) and pull factors (such as employment opportunities and better access to healthcare and education) draw large numbers of people to primary urban centers. 2. High rates of natural increase within the cities, as the migrating population is predominantly made up of young adults of reproductive age, leading to high birth rates compared to death rates in urban areas.

Marking scheme

Award [1 mark] for identifying a valid reason and [1 mark] for its explanation, up to a maximum of [4 marks]. Reason 1 (rural-urban migration): [1 mark] for identifying rural-to-urban migration. [1 mark] for explaining how push/pull factors drive massive population shifts to major urban centers. Reason 2 (natural increase): [1 mark] for identifying high natural increase. [1 mark] for explaining how the youthful demographic profile of urban migrants leads to high birth rates in these urban centers.
Question 6 · short_answer
4 marks
Explain how the ice-albedo feedback loop contributes to global climate change.
Show answer & marking scheme

Worked solution

The ice-albedo feedback is a positive feedback loop that accelerates global warming: 1. Rising global temperatures cause polar ice sheets, glaciers, and sea ice to melt. 2. This melting replaces highly reflective white ice and snow surfaces with darker land or open ocean surfaces. 3. These darker surfaces have a lower albedo (reflective capacity) and absorb more shortwave solar radiation instead of reflecting it back into space. 4. This increased absorption of solar energy warms the local environment further, leading to even more ice melt and continuing the warming cycle.

Marking scheme

Award [1/2 marks] for each logical step in the explanation of the feedback loop, up to a maximum of [4 marks]. Step 1: Link rising temperatures to ice/glacier melting [1 mark]. Step 2: Link melting to reduced surface albedo / exposure of darker ocean or land [1 mark]. Step 3: Explain that lower albedo means increased absorption of shortwave solar radiation [1 mark]. Step 4: Link increased absorption to further local/global warming and subsequent ice melt [1 mark].
Question 7 · short_answer
4 marks
Suggest two reasons why women in low-income countries are often more vulnerable to the impacts of climate change than men.
Show answer & marking scheme

Worked solution

Women in low-income countries face greater climate vulnerability due to: 1. Traditional gendered divisions of labor, which make women responsible for securing household water, food, and fuel. Climate-induced droughts increase the distance they must travel, increasing their physical burden and reducing time available for education or income. 2. Unequal access to resources and legal rights, such as land tenure rights and financial credit, which limits their ability to invest in climate-resilient farming techniques or recover after climate-related disasters.

Marking scheme

Award [1 mark] for identifying a valid reason and [1 mark] for its development/explanation, up to a maximum of [4 marks]. Reason 1 (labor division/resource collection): [1 mark] for identifying women's responsibility for securing basic resources. [1 mark] for explaining how climate events like drought increase travel distances and vulnerability. Reason 2 (inequality in resource ownership/rights): [1 mark] for identifying limited land ownership or financial access. [1 mark] for explaining how this restricts their capacity to adapt or recover from climate disasters.
Question 8 · short_answer
4 marks
Explain two ways in which the Food-Water-Energy (FWE) nexus can be managed to improve resource security.
Show answer & marking scheme

Worked solution

The FWE nexus can be managed by: 1. Implementing drip irrigation powered by solar energy, which reduces water waste in agriculture while utilizing renewable energy, thereby securing water and energy resources simultaneously. 2. Utilizing agricultural crop waste for biogas production, which provides decentralized energy and organic fertilizer, reducing the dependence on fossil fuels and chemical inputs while securing energy and food systems.

Marking scheme

Award [1 mark] for identifying a management strategy/approach that addresses at least two nodes of the nexus, and [1 mark] for explaining how it improves overall resource security, up to a maximum of [4 marks]. Strategy 1: [1 mark] for identifying a nexus-based technology or practice (e.g., solar drip irrigation). [1 mark] for explaining how it co-manages resources (e.g., reduces water usage while avoiding fossil fuel consumption). Strategy 2: [1 mark] for identifying another practice (e.g., bioenergy from crop waste). [1 mark] for explaining how it links food production and energy generation to build resilience.
Question 9 · short_answer
4 marks
Explain two reasons why a nation's ecological footprint typically increases as it experiences economic development.
Show answer & marking scheme

Worked solution

A nation's ecological footprint increases during development due to: 1. Changes in dietary patterns, specifically a transition towards a higher-protein, meat-heavy diet (nutrition transition), which requires significantly more land, water, and energy resources than plant-based diets. 2. Increased energy consumption and industrialization, where rising incomes lead to higher ownership of vehicles and electrical appliances, raising the demand for fossil fuels and increasing carbon dioxide emissions.

Marking scheme

Award [1 mark] for identifying a valid reason linked to economic development and [1 mark] for explaining how it increases the ecological footprint, up to a maximum of [4 marks]. Reason 1 (dietary shifts / nutrition transition): [1 mark] for identifying the shift to meat/processed foods. [1 mark] for explaining how meat production requires disproportionately high land and energy inputs. Reason 2 (energy consumption / consumer goods): [1 mark] for identifying rising consumption of consumer goods/cars. [1 mark] for explaining how this increases fossil fuel demand and carbon footprint emissions.

Question 3 · short_answer
2 marks
Using the provided photograph of the reservoir behind an upstream dam, suggest one piece of visual evidence that indicates potential water insecurity for nations located further downstream.
Show answer & marking scheme

Worked solution

Candidates are expected to link a visual observation from the reservoir photograph to the concept of downstream transboundary water insecurity. For example, pointing out the low water level (exposed dry shoreline or bathtub ring) or an arid landscape surrounding the basin. This visual evidence represents a physical shortage of water upstream, meaning less water will be released or is available to flow downstream. Consequently, downstream populations face reduced river flow, leading to crop failures, lack of potable water, or decreased hydroelectric power generation, which exacerbates transboundary conflict.

Marking scheme

Award 1 mark for identifying a valid piece of visual evidence from the photograph (e.g., exposed dry shoreline/sediment, low reservoir water levels, or a dry river channel below the dam). Award 1 mark for explaining how this visual evidence connects to water insecurity or reduced supply for downstream nations (e.g., lower river discharge, reduced agricultural irrigation capacity, or increased political tension over scarce transboundary resources). Maximum 2 marks.
Question 4 · To What Extent Synthesis
6 marks
Using examples, to what extent do geopolitical power asymmetries determine the success of transboundary water management treaties?
Show answer & marking scheme

Worked solution

Synthesis of Key Arguments:

  • Geopolitical Power Asymmetries (Upstream vs. Downstream): Powerful upstream nations (such as China on the Mekong, or Turkey on the Tigris-Euphrates) can construct infrastructure and divert water with minimal regard for downstream neighbors, often dictating terms or avoiding binding multilateral treaties. Conversely, a powerful downstream nation (such as Egypt on the Nile) may historically dominate water allocation agreements, although this hegemony can be challenged by developing upstream nations (such as Ethiopia with the GERD).
  • Role of Treaties: Resilient treaties, such as the Indus Waters Treaty (India and Pakistan) or the Danube River Protection Convention, show that institutional frameworks can survive intense geopolitical tensions and promote cooperative water resource management.
  • Other Influencing Factors: Climate change-induced physical scarcity, third-party mediation (such as the World Bank), and mutual economic benefits (such as shared energy grids from joint hydroelectric projects) can either destabilize existing treaties or compel cooperative behavior regardless of power imbalances.

Conclusion:

While geopolitical power imbalances significantly shape the leverage and initial terms of transboundary water agreements, they do not solely determine long-term success. Robust institutional designs, external mediation, and mutual economic dependencies can mitigate power asymmetries to foster sustainable transboundary water security.

To what extent are civil society organizations (including non-governmental organizations) more effective than national governments in building resilience to the impacts of global climate change?
Show answer & marking scheme

Worked solution

### Introduction
- **Definitions**: Define 'resilience' (the capacity of a community or system to adapt to and recover from climate hazards) and identify the two main actors: civil society organizations (CSOs/NGOs) and national governments.
- **Thesis**: While CSOs are highly effective at localized, community-level adaptation and addressing immediate vulnerabilities of marginalized groups, national governments are indispensable for large-scale infrastructure, policy frameworks, and national funding. Thus, CSOs are not universally 'more' effective, but rather complementary to state-led efforts.

### Arguments for the Effectiveness of Civil Society Organizations (NGOs)
- **Localized, Bottom-Up Approach**: NGOs work directly with vulnerable communities, adapting solutions to local contexts (e.g., promoting drought-resistant farming techniques or community-managed mangrove restoration in coastal Bangladesh).
- **Inclusivity & Vulnerable Groups**: CSOs often target marginalized groups (women, indigenous communities, urban poor) who are frequently overlooked by national governments.
- **Flexibility and Speed**: Free from rigid state bureaucracy, NGOs can respond rapidly to changing local conditions and trial innovative resilience practices.

### Arguments for the Effectiveness of National Governments
- **Scale and Infrastructure**: Only governments can mobilize the capital and authority required for mega-scale protective infrastructure (e.g., the Delta Works in the Netherlands, sea walls, or national early warning systems).
- **Legislative and Policy Frameworks**: Governments control national land-use zoning, building codes, and national adaptation plans (NAPs) that legally mandate climate-resilient practices.
- **Funding and Diplomacy**: Governments access global climate funds (e.g., Green Climate Fund) and negotiate international agreements (e.g., Paris Agreement) that shape the broader funding landscape for resilience.

### Synthesis and Evaluation
- **Interdependence**: NGOs often depend on national governments for legal permission to operate and for scaling up successful pilot projects. Conversely, governments require NGOs to implement and gain community trust for policies on the ground.
- **Conclusion**: Civil society is significantly more effective at micro-level, participatory adaptation and addressing social vulnerability. However, they cannot replace the top-down structural capacity of national governments. Therefore, maximum resilience is achieved through a multi-level governance approach where both actors work in partnership rather than in isolation.

- Highly descriptive with few or no specific examples.
- Lacks a clear structure and a direct response to the 'to what extent' prompt.

* **Level 2 (4–6 marks)**:
- Demonstrates an understanding of how both civil society and governments build climate resilience.
- Mentions appropriate examples (e.g., specific country contexts or adaptation projects), though they may lack detail.
- Provides a basic evaluation of both sides, but the argument may be unbalanced or lack a well-justified conclusion.

* **Level 3 (7–10 marks)**:
- Detailed, balanced, and well-structured evaluation of both civil society and national governments.
- Integrates precise, relevant geographical case studies/examples (e.g., NGO work in LICs vs. national policies/infrastructure in MICs/HICs).
- Explicitly addresses the 'to what extent' command term, arriving at a nuanced conclusion about the interdependence of both actors.
