Title

Evaluation of Conveyance Efficiency and Water Seepage Loss in Irrigation Canals with HDPE Geomembrane Lining in Plains of Zaiandeh-Rood, Moghan and Kerman

Pages

  725-735

Abstract

 The level of water losses in 7 irrigation canals in plains of Zaiandeh-rood, Moghan and Kerman, with the same specifications of HDPE geomembrane lining of the same age, were evaluated. The losses of water in the canals was determined by input-output method in three stages. At the same time, the volume of evaporation using a class A pan installed in the coming next canals, was determined. To calculate seepage losses, the level of evaporation losses were deducted from the total ones. Based on the results, the level of efficiency stood between 95. 9 and 99. 7 and on the average it was 98. 9 percent. The total losses in the canals were determined between 3. 3 to 13. 8, and on the average 11. 5 lit/s per kilometer. From total losses, between 3. 3 (Zaiandeh-rood) and 16. 2 (Kerman) and on the average some 7. 1 percent was due to evaporation and the remainder due to seepage from geomembrane lining. The seepage losses in evaluated canals was between 0. 03 (KC in Kerman plain) 0. 16 (EC4 in Zaiandeh-rood) and an average of 0. 1 m3/m2/day (17 times below the concrete lining). The results of the study showed remarkable impact of geomembrane lining in control of water losses from irrigation canals and the advantages as compared with the conventional concrete lining.
