A design procedure for closed end irrigation borders

Criteria for the design of closed end irrigation borders are generally based on intake rate and irrigation advance for specified inflow and irrigation efficiency. Recession has seldom been included in the design. This study emphasizes inclusion of temporally varying intake rate, irrigation advance, vertical recession, horizontal recession and recession of impounded water. To determine the length of impounding, an iterative procedure is proposed correlating irrigation advance and recession with the depth of flow at the up-stream end. To evaluate the design, irrigation efficiencies are computed for specified conditions and are compared with those based on experimental data.
