<br/><br/> The Ministry of Water Resources and Irrigation (MWRI) , has implemented various structures and facilities along the Nile River to release water in accordance with man's requirements and needsVarious barrages have been built a on the Nile River in order to regulate water distribution and control flows to maximize profitability and minimize losses , such as Esna , and Naga Hammadi BarragesDuring the testing of New Esna Barrage design and performance on a physical model , it was observed that the scour immediately downstream the stilling basin exceeded the expected valuesThis observation has been verified further during the monitoring of the actual structureThe same findings were also observed during the design and model testing of New Naga Hammadi BarrageIn both cases significant design modifications has been introduced using trail and error based on expert's opinionTherefore , there is a need to develop and improve some design criteria for hydraulic structures to be used in future applications and suitable for the Nile River conditions
