Abstract

1-Introduction: There are strong links between the availability of water for agricultures and livestock productions, and the incomes for poor rural nation. Rainfall variations, particularly droughts, effect on their living as well One meaning of increasing people’ s resilience to these shocks is to store water in dams – so that crops can be irrigated and cattle watered during dry seasons. Many of the small dams are constructed in semi-arid regions of Africa which is rapidly filled with sediments and sometimes only after a few years. When dams silt up the rural areas that is relied on them for cattle watering or smallscale irrigations that deprived of the water and food security that dams provide them, and their source of income is seriously affected too. Predicting soil erosions, sediment yields and dam sedimentation rates can be a complex task, it requires professional experts, and in generally it has poorly covered in small dam design manuals. These results in many small dams constructed with little or no consideration of the impact of future siltation of a dam’ s life or on water yields. This issue is poorly covered in most small dam design manuals, which mostly focuses on civil engineering designing and construction aspects. A capability to estimate future siltation rates in small dams is essential to ensure that: dams are not constructed in catchments with excessively high sediment yields; dams are sized correctly; catchments where the rapid introduction of soil and water conservation or other measures will be essential if a reasonable dam life is being obtained, are identified early enough for remedial activities to have a significant impact on dam siltation....
