| Abstract | A study was conducted in the Ganges-Kobadak (G-K) irrigation
project of Bangladesh during the Kharif-I (dry) season of 1978.
Different aspects of water use for lowland rice and the corresponding irrigation water supply in the selected areas of the project were studied.
Results of the study revealed that seepage and percolation
losses varied from 3.88 to 6.96 mm/day and the net water use i.e. evapotranspiration plus seepage and percolation ranged from 7.82 to 10.90 mm/day in different areas. Water supplied through the canals was found
to be much more than the actual requirement and comparatively higher water supply was observed at the upstream areas. Aiso, no definite schedule of water supply was found to exist in the system. High water use efficiency was found at the downstream areas compared to the upstream areas indicating excessive loss of the supplied water at the upstream areas. On the other hand, the water adequacy was observed to be higher in the areas nearer to the source of water. |
