Abstract (2. Language): 
For irrigation projects with limited water resources, or restricted supplies from pump capacities irrigation management decisions need to be taken well before the irrigation season. Irrigation managers need to anticipate crop selections, plan for crop rotations, and project water deliveries to each crop. To take such decisions a water allocation model has been built to determine optimal crop area to cultivate by each crop among crop mix of two to six crops under the constraint of prevailing climate conditions, available water resource and critical command area with the objective of attaining the optimum critical area. The mathematical model of the problem is linear in nature subject to various constraints due to availability of total land area, water. Consequently, linear Programming was used in this study to make decisions about irrigation water management options in conjunction with optimal cropping patterns to ensure optimal use of water. The developed model is also capable of matching scheme water demand and supply through many different scenarios including: staggering of the sowing date, increasing scheme water supply, changing the operational criteria of the scheme, changing crop variety and eventually increasing the overall irrigation efficiency. The computer model’s accuracy has been validated by taking different water management scenarios under the prevailing conditions of Rahad Irrigation project.
