Management Issues and Strategies
Dams and reservoirs
- Examine the hydrological changes resulting from the construction of dams and reservoirs.
- Examine the costs and benefits of dams and reservoirs as part of multi-purpose schemes.
- Explain the stream channel processes (erosion, transport, deposition) and explain the resultant landforms found on floodplains.
- Examine the human modifications of a floodplain and their effect on the size and probability of floods.
- Evaluate the costs and benefits of alternative stream management strategies.
- Explain the functioning and management of artesian basins and aquifers, distinguishing between natural and artificial recharge.
- Examine the environmental impacts of groundwater abstraction.
Freshwater wetland management
- Describe the role of wetlands as a water resource.
- Evaluate the effectiveness of the management strategies that have been adopted in a major wetland.
Irrigation and agriculture
- Examine the environmental impact of agriculture and irrigation on water quality: salinization, agro-chemical run-off, the pollution of groundwater and the eutrophication of lakes, rivers and wetlands.
