Abstract | A study was carried out during the dry season of 1985 at the experimental site of Asian Institute of Technology, with no vegetation to determine the effect of nonuniform water advance in level basin irrigation on distribution uniformity and to develop a monograph for design and operation of this irrigation method. Level basins of sizes 4m x 10m, 10m x 10m and 20m x 20m with stream sizes 4 lit/sec, 7 lit/sec and 10 lit/sec were used. A depth of 10 cm water was applied to all basins and data were collected on advance of water front with photographs at selected time interval. Water distribution uniformity and uniformity coefficient were calculated. it was found that higher stream size gave highest distribution uniformity and uniformity coefficient with smaller basin size. Assuming water front advances uniformity, it was found that uniformity coefficient for uniform advance was higher than nonuniform advance. The effect of intake family on uniformity coefficient was also simulated. It was concluded that for higher intake families the effect of nonuniform advance on uniformity coefficient was likely to be less than 5% |
