Flow fluctuation in a canal reach occurs due to variation of flow rate al the headworks, by gate settings and by varying the waler demands. These flow variations ultimately get transmitted to turnouts flow rale and lateral spill. The degree of non-uniformity in flow deliveries amongst the turnouts because of flow variability in a reach (due to various possible reasons) and sedimentation in a reach has been studied in a simple hypothetical canal system. Simulations of hydraulic parameters have been done using the model CANALMAN developed at Utah State University, USA. Structural and operational improvements which can bring reduction in the nonuniformity in flow distribution have also been discussed.
