Assessing Potential for Sand Dam Wadi Developments in Somalia


Water Practice wished to explore intervention options for implementation in the south of Somalia. As such, sand dam and sub surface dam site selection is crucial and the World Bank has undertaken a pre-feasibility study for developing wadis in the south-central area (Galmudug + South West states). The WET was developed by HYDROC during the previous “Macro level study on the integrated development potential of sand-river wadis of Somaliland and Puntland”. After the Wadi Evaluation Tool (WET) was updated with additional data and parameter refinements, a total of 30 sites was proposed – 15 in each state. Further feedback from previous applications of the tool by local stakeholders was gathered and the WET updated accordingly. Subsequent ground truthing missions were conducted to confirm the findings of the remote WET in the field and a final selection of sites was presented to the client.

Actual services provided by our staff within the assignment:

Activities include the compilation, edit and enhancement of existing datasets for WET for new regions and application of the WET model for the pre-selection of sites in the new regions, ground truthing missions, review of ground truthing results and inclusion of findings into WET -> refinement of site selection. Compilation of outputs (digital PDF maps and short summary report)
