Tharthar

Detailed Inspection and Evaluation for all the Structures by qualified consultants is required In order to define the required maintenance and /or replacement and improvement works . Sedimentation surveys of Iraq’s rivers carried out by MoWR indicated considerable amounts of sediments that need to be dredged from the upstream of Samarra Barrage , the estimated amount there is some 56.5 million cubic meters . the extent of Sediment removal should be based on hydraulic model tests . therefore a bathymetry survey is needed upstream and downstream the barrage and Tharthar inlet Regulator. Then a model constructed to test different solutions of river training works and the extent of sediments dredging works .

The scheme was constructed for the Flood control of Tigris river and offer safety for the downstream areas and the Capital Baghdad , this is done by diverting part of Tigris River water during flood via the constructed flood escape regulator and the flood escape channel to Tharthar lake which originally was a natural depression created by storing the diverted water during flood time since 1956
