Abstract

The Sangkulirang-Mangkalihat area has tremendous natural resources one of them is water resources. The availability of water in karst area needs to be recognizing in order to fulfill the water demand of the community around karst area. This study aims to identify water availability and water demand in karst area. Water availability identified by Thornthwaite-Mather water balance method and calculation of water demand performed for domestic water demand, agricultural water demand and livestock water demand. The result shows that annual rainfall of karst area is 2036 mm/year. The amount of water availability is 177.6 million m3/year, while domestic water demand is 1.33 million m3/year, agricultural water demand is 73 million m3/year and livestock water demand is 142.8 thousand m3/year. Comparison between the availability of water and the water demand of karst area shows that the water conditions are still able to meet the needs of the community.
