| dc.description.abstract | This study was carried out aiming at determining the suitable crops that can be grown in the upstream catchments of Pangani basin based on the available water so that the downstream demand especially for power production can be met. The amount of water that could be flowing into the reservoir without irrigation abstractions was estimated using Linear Perturbation model. The amount of water that could be safely abstracted upstream without affecting the supply downstream was then estimated by deducting the downstream firm demand and reservoir evaporation from the output of the model. Estimation of the reservoir evaporation was done using Morton’s complimentary relationship. Irrigation water requirement for the existing crops in the area was estimated using the Penman Monteith equation, which is incorporated in the FAO program for irrigation management, and planning known as CROPWAT. The comparison between the present demand and the estimated available water in the area indicated that the estimated available water could not meet the present demand in the area. An attempt was then made to see if by varying the areas occupied by the existing crops the demand could be met. The results obtained indicated that, the demand could not be met. Other suitable crops for the area were determined using the procedure proposed by FAO. Among the selected crops sorghum and wheat were proposed instead of rice and sugarcane and it was found that, with these crops the demand downstream can be met. | en_US |
