TunisiaWES project concluded its activity on the sedimentation issues of Tunisian reservoirs
The EU funded “Water and Environment Support (WES) in the ENI Neighbourhood South Region” project is supporting Tunisia in tackling the problem of sedimentation in its dams since 2020, by preparing and implementing an Activity “Reservoir Sedimentation Hazard and Mitigation Measures towards Sustainability in Tunisia”.
This WES Activity deals with the combined effects of runoff and soil erosion on the sedimentation issues of Tunisian reservoirs which significantly eliminate their storage capacity and focuses on two reservoirs: (a) the Lebna Reservoir on the Mediterranean Coast, and (b) the Sieliana Reservoir on the country’s upland area with useful storage 70 and 30 million cubic meters respectively.
During the first two days, the agenda expanded from the outcomes of the study on the sediment yield/reservoir sedimentation and the sustainability of Natural Water Retention and soil Measures (NWRSMs) in Tunisia to combat erosion and desertification and the results from both pilot cases alongside the cost/benefit analyses to illustrate the viability for the general application of NWRSMs in the country for preventing soil loss, to the guidelines/criteria for the selection of appropriate sites for applying these measures. In addition, a useful and valuable dialogue was established between stakeholders.
