Satellite data use in the WEAP Model as an evaluation of Water Availability in Unda River Basin

Abstract

Unda river basin is one of the potential river basin in Bali Province of with a perennial river so that water availability is available every year. Even though it has a great potential, the river basin management is not optimal so that during the dry season there is still a lack of water. Water Evaluation and Planning (WEAP) is a model that can combine hydrological processes with management of water allocation in a catchment area. This model can evaluate the water availability in the Unda river basin. WEAP has a tool that is automatic delineation mode that can be used to automatically delineate catchment areas, land cover data and climate data based on satellite data which can make easier to modelling. The results of this study can be used as an evaluation in the water availability in the Unda River Basin so that the potential in the Unda River Basin can be optimal and sustainable.
