Assessment of the Rehabilitation of Watercourses (Study Case)

The goal of this study is to assess the rehabilitation Bahr Awlad Mohamed canal.The canal was rehabilitated by installing lining trapezoidal cross-sections. Before and after process, a field investigation, hydraulic hydrographic measurements, mathematical model (Sobek – 1D) were conducted. According findings, canal's improved average water velocity from 0.18 m/s 0.32 m/s, Manning roughness coefficient 0.065 m-1/3s 0.020 m-1/3s, surface slope 17 50 cm/km 2 6 cm/km, areas cross-sections reduced 3.37 m2 3.07 m2, width 5.84 m 4.83 m, losses decreased approximately 27.31 % inlet discharge. Additionally, level fulfilled requirements for distribution, banks restored widened, efficiency improved, alleviating downstream farmers' concerns conserving that could be utilized irrigation, saving time maintenance cost. Finally, necessitates periodic maintenance, appropriate equipment, strategy preservation. In addition, other canals in Egypt must determine irrigation network's water-saving potential.
