Journal Title: Academic Research International - Year 2014, Vol 5, Issue 6
Abstract
Watershed Batulicin South Kalimantan Province is a watershed with handling priority in Indonesia (Ministry of Forestry Decree No. SK. 328 / Menhut-II / 2009). In Government Regulation No. 37 Year 2012 on Watershed Management it was stated that the priority watershed is the watershed whose carrying capacity needs to be restored. Floods in South Kalimantan province including in Watershed Batulicin in the period from 2007 - 2010 was increasing. Based on those facts mentioned above, it is necessary to carry out a study on controlling flood vulnerability in Watershed Batulicin. The purposes of this study were to find out the characteristics of watershed hydrology that became the parameters to determine the flood vulnerability level, and as a reference to determine the direction of policy priorities of Watershed Batulicin management, in order to obtain optimal results for flood control. It was a descriptive quantitative study, providing a spatial overview of watershed characteristics, which was measured quantitatively. This study used a watershed ecological region approach, where the analysis process and the presentation were conducted spatially. The results of the study indicated that the characteristics of watershed comprised of: a) the shapes of the watershed consisting of two rounded sub-watersheds and five elongated sub-watersheds; b) the dendritic drainage pattern; c) the river networks, namely 3 lower density sub-watersheds and 4 medium density sub-watersheds; d) the land covers dominated by 33.1% of secondary dryland forest, 23.6% of dry-land agriculture and 14.1% of plantation, e) coefficient of river regime in 1995 - 2004 between 1:2 to 1:15, and in 2014 1:21, f) very critical land of 8,257.44 ha (5.78%).
