– 3 – N05/3/GEOGR/BP2/ENG/TZ0/XX/M SECTION A A1. Drainage basins and their management Either (a) Essay Describe and evaluate the success of the water management strategies of one named drainage basin. [20 marks] A drainage basin should be selected where there is more than one strategy and this is likely to be a multipurpose scheme. The multipurpose function of the chosen management strategies should be described in some detail. It should be recognised that multipurpose basin management schemes aim to match water supply with demand from an increasing range of uses. Such multipurpose functions might include meeting domestic, industrial and agricultural demands as well as those from recreation, energy, transport and conservation. Flood and drought control may also be part of the strategy. Evaluation is an essential requirement of the question and should address the bene±ts and costs of the scheme from a variety of perspectives. These might include physical and human, local and national, short-term and long-term consequences. A maximum of [12 marks] should be awarded for a descriptive response showing no evaluation. Responses accessing the top markband should include detailed and accurate factual information concerning the speci±c multipurpose scheme chosen. Marks should be allocated according to the markbands. Examiners should be aware that candidates may take a different approach which, if appropriate, should be fully rewarded.

– 4 – N05/3/GEOGR/BP2/ENG/TZ0/XX/M Or (b) Structured question (i) Explain the development of the Fuvial landscape shown in each photograph (A and B). Use diagrams to illustrate your answer. [5+5 marks] Marks should be equally allocated [5 marks + 5 marks] to each explanation of the two Fuvial landscapes. In each case a neat and well-annotated sketch may substitute for some of the written explanation. Where diagrams are missing, a maximum of [3 + 3 marks] should be awarded. Photograph A shows a braided river channel with a number of inter-connected channels separating the islands or eyots [2 marks] . The remaining [3 marks] should be allocated to the explanation of the development of this landscape. The best responses should include the following points: Braiding is commonly found in rivers with variable discharge carrying a large sediment supply; typically areas of deserts, monsoon climate and snowmelt. When discharge is high, large sediment loads can be transported and when discharge is reduced, the river’s carrying capacity drops resulting in deposition and the formation of eyots. Photograph B shows a Foodplain with a sinuous or meandering river channel
