An Estimation of Annual Sediment Load for Egyptian Irrigation Canals.(Dept.C)

Erosion, transport, and deposition processes in alluvial channel are considered one of the complex phenomena due to limited knowledge theory interaction between water sediment flow, predicting behaviour courses. In last thirty years although experience transport both practice as well increasing capacity digital computers numerical techniques have provided a substantial aid this field, but mechanics transportation is still considerably far from being satisfactory. Four conventional bed load formulae been applied some selected Egyptian irrigation canals. Located Delta region. Limitations each formula discussed, most appropriate has used for an estimation annual these
