Abstract

The irrigation diversion requirement (IDR) refers to the quantity of water needed to satisfy the farm irrigation requirements and to replenish the amount of water lost during diversion. The IDR aids in the design and evaluation of the capacity of irrigation canals and estimation the irrigable area (IA). The IDR in Division I of the UPRIIS was evaluated using the engineering cropping pattern and the FAO-Cropwat 8.0. The IDR depends upon the growth stage of the crop and the climatic conditions in the area. In general, IDR was observed to the higher in dry season than in wet season. The estimated IDR from the engineering cropping pattern varied from the actual IDR with 61% (dry season) and 34% (wet season) difference. On the other hand, the FAO-Cropwat exhibited closer estimates with 9% (dry season) and 25% (wet season) difference from the actual. The IA varies according to the estimated IDR and the actual discharge in the area. The IA was observed to be generally lower in dry season than in wet season. The IA computed from the engineering cropping pattern varied from the actual at 37% (dry season) and 57% (wet season) difference while as the IA from the FAO-Cropwat 8.0 varies from the actual at 8% (dry) and 40% (wet) difference. The computation of accurate IDR may require a lot of effort but correct IDR value is needed in order to obtain the realistic irrigable area.
