ABSTRACT
A linear programming simulation model and a multi-objective analysis model have been developed and applied to a large irrigation system, Phitsanulok Irrigation Project, Thailand, to optimize water resources release planning from a reservoir during the dry season. The simulation model carries out sensitivity analysis to sort out promising pareto-optimal irrigation policies in terms of the system's primary objectives: net economic benefit, equity and security. The multi-objective analysis model analyzes the trade-offs between the contrasting, conflicting and non-commensurable objectives. The irrigation policy, ranked top by the model, is compared with the observed and preseason planned irrigation policy. For the effective implementation of this optimized irrigation policy, empirical relationships are developed analyzing the historical data to quantify the water availability at the field from a particular reservoir release. These empirical relationships enable prediction of the necessary reservoir release required to satisfy the irrigation system demand.
