Abstract:The British Government's Department for International Development commissioned HR Wallingford to develop guidelines presenting appropriate methods for predicting, and where possible reducing, siltation rates in small communal dams in semi-arid zones in Eastern and Southern Africa. Small dam designers must be able to use these methods; they typically need to carry out assessments rapidly using limited local data, and may not have software skills or access to computers. The report describes the development of a method for predicting small dam catchment sediment yields. The objective was to develop a simple procedure which would distinguish between dams that will silt up rapidly from dams that will have a sedimentation lifetime well in excess of twenty years.
