Résumé
This report reflects the results of a research project concerning the hydrology around sand storage dams. The Kitui district is one of the arid and semi-arid lands of Kenya. For (drinking)water most people heavily rely on water supply from the riverbeds of ephemeral rivers. SASOL is a local NGO which builds so called sand storage dams in ephemeral rivers to increase the water availability during the dry season. Sand storage dams are small (generally a few meters high) dams built in the riverbed behind which sand accumulates, enlarging the natural aquifer. The groundwater in the riverbed is obstructed by the dam and retained between the pores in the sand, making it available for people and animals during the dry season
