Study of Oos River Basin characteristics for sustainable water availability

Abstract

Oos River Basin is one of the perennial river basin in Bali, whose water potential is widely used as raw water and irrigation water mainly for the Gianyar Regency. Even though it has great water potential, according to the BWS Bali-Penida (2012), 18.84% of its area is classified as critical land and 81.16% is classified as very critical. If it is not managed in an integrated manner, then this will have an impact on the sustainability of existing water availability. This study will examine the characteristics of river basins that are very important to be used to determine the condition of the river basin and how to maintain the sustainability of the existing water potential. The data needed in this research is Oos river basin boundary map data, Oos river basin river network map, topographic data, land use and maps of soil types. The results of this study will be in the form of Oos River Basin characteristics and river basin management recommendations for the sustainability of its water potential.
