abstract rockfill dams are a type of hydraulic control structures used to protect river bed in cases where a considerable reservoir volume is available behind these structures; it could mitigate the floods and provide a gradual depletion of incoming volume of water so that the discharge passing downstream is decreased. one of the main issues on utilizing rockfill dams is to keep its permeabilit...

Dams are essential infrastructure for managing water resources and providing entry to clean human needs. However, the construction maintenance of dams require careful consideration their reliability safety, specifically in event extreme weather conditions such as heavy rainfall or flooding. In this study, stress-strength model provides a useful framework evaluating ability cope with external st...

The repetition of droughts in France has led to a growing demand for irrigation water and consequently to an increase in requests for the construction of small farm dams. Although such dams are small, their accumulation in a basin affects river flows, because the water collected in these small farm dams is used for irrigation and thus does not contribute to river flow. In order to gain more ins...

Water conflicts arise from geostrategic factors that hide behind visible ones such as the construction of dams. In case Grand Ethiopian Renaissance Dam (GERD), it will have a significant impact on development in Ethiopia, but its filling has worried downstream countries about altering flow Nile and associated ecosystems. this study, several high spatiotemporal resolution remote sensing products...

This paper presents the results of an evaluation of the effects of a local water harvesting project in Kenya concerning the construction of small scale sand dams by communities. Sand dams are small structures built in ephemeral rivers to store excess water to overcome periods of drought. For this evaluation we developed a method using socio-economic vulnerability indicators, which are linked to...
