Abstract

Roodasht irrigation network is placed at downstream of Zayanderood River. A recent problems in the operation of the network is INFLOW FLUCTUATIONS in the main canal because of flow variations at upstream of the river. Thus, enhancing utilization of operational condition of the main canal becomes essential. In this study, the operational performance of the LAT PROPORTIONAL WEIRS under INFLOW FLUCTUATIONS was investigated and compared with the Nyrpic Module Off-takes for a realistic operational period of time. To achieve the mentioned objectives, mathematical models of the both systems were developed and their operational performance was evaluated within equity, adequacy, and efficiency of water delivery point of views. With regards to the obtained results, both systems showed a more or less same performance from of adequacy and efficiency in upstream and downstream off-takes. Comparing the calculated equity performance index revealed that employing the LAT system leads to 19% decreasing of fairly water deliveries along the canal. In conclusion it can be suggested that no advantageous are gained by replacing the existing Nyrpic Module Off-takes employed with the LAT system.
