Modeling at this scale can provide essential information for policy makers in their decisions on allocation of resources. Simulation and optimization are two principal approaches to river basin modeling. This study performs a detailed simulation of the Mun River Basin situated in the northeastern part of Thailand. The Mike Basin model, developed by the Danish Hydraulic Institute, is used to simulate the system. The technique used in the model is a basic water quantity mass balance approach. The output of the model is analyzed in terms of event-based reliability. Based on the availability and utilization of water resources in the Mun River Basin, a monthly simulation is applied using hydrological data from 1965 to 1997. Various scenarios of water resources development of irrigation projects, and domestic and industrial water supply projects are considered in the simulation. It was found that overall reliability of the irrigation system is 42 percent and water supply system is 38 percent. The low reliability is due to the very high variation between dry season and wet season water availability. Water availability in the wet season was found to be almost six times more than that in the dry season. Sensitivity analysis on cropping intensities of irrigation schemes indicates that reliable wet season cropping across the basin is 79 percent, and reliable dry season cropping across the basin is only 12 percent. The analysis also indicates that dry season cropping in most of the areas (mainly in the central part) is not feasible. Finally, based on the above findings, some water management plans for the Mun River Basin are recommended.
