Abstract
Cambodia has been actively developing its land use from forests to farmland or plantations. As a result, population, plantations, and agricultural land are increasing and the water resources must depend on groundwater. Therefore, the importance of groundwater as a water resource is increasing. Annual fluctuations of simple water cycle processes, with transitions from vapor in the atmosphere to groundwater, and transpiration processes that release soil water to the atmosphere are interesting to consider when assessing stable use of groundwater. The results of the monitoring data of simple water cycle processes I Kampong Thom, central Cambodia, show that the annual precipitation depends on the number of high-precipitation events rather than on the number of annual precipitation observation days and the dry evergreen forest examined for this study was judged as consuming water to the greatest extent potential with no restrictions. It is concluded that groundwater is useful for stability even if dry evergreen forests are developed into plantations and agricultural lands.
