Abstract

In this research, CONVEYANCE AND DISTRIBUTION EFFICIENCIES of 5000 ha. SHAWOUR IRRIGATION AND DRAINAGE NETWORK located at the Khuzestan province of Iran, were estimated using field measurement. For this purpose, the flow losses at some selected un-lining channels were calculated using inflow-outflow measurement method. Then based on this calculation, losses coefficients in unit length of the channels and the CONVEYANCE AND DISTRIBUTION EFFICIENCIES of the channels using the exponential equation were estimated. The results show that the canals conveyance efficiencies varies between 34 and 83% and in average is about 60%. Also, the distribution efficiency of the channel network is from 45 to 86.5% and average is about 71%. These very low efficiencies of the Shawour irrigation network are very critical and disappointing. Therefore, in order to increase irrigation efficiencies, an application of water and soil resources have to be employed using management methods. Considering the results of this research, increasing the water application efficiency needs several modifications including: channel geometric modifications and lining.
