| Abstract | The study aims to attempt to give a critical state-of-the-art review of previous models in irrigation planning. Critical issues in irrigation planning has been presented and its relationships to irrigation water management as a framework for irrigation development planning. The Lam Pao Project was used as a case study to identify problems in irrigation planning and use LP approach to solve these problems The command area experienced maldistribution of irrigation water among farms. To solve this problem lies on the equitable distribution of water among farms. This can be achieved by a continuous control of water delivery based on the approved cropping pattern, improvement on the controllable distribution of water from the point of diversion to the service area. A LP model was formulated and applied to Lam Pao command area. This linear optimization model maximizes the total net benefit from all crops under consideration subject to total water available for diversion, irrigation land classes, and crop diversification constraints. The land area t o be allocated to each crop and surface water diverted were the decision variables. Results from this area-allocation model include optimal cropping pattern, total net benefits of crops, surface water supplied. Sensitivity analysis was performed to study the changes in cropping intensities, adding crop constraints and irrigation fees in terms of area and volume basis to study the effect of changes on area-allocation on the optimal results. |
