Land use conducted in accordance with its ability to protected areas or farm area in a watershed will provide benefits for the benefit of the water system and the welfare of society. Land use do not match the capabilities and purposes may increase the risk of floods. Balitbangda South Kalimantan (2010) states that the period from 2007 to 2010, in Banjar Regency flood inundates 10 districts and 65 villages. This study aims to determine the land capability class and determine the direction of land use to control flood vulnerability, while the benefits are not expected to be a reference control flood vulnerability to short-term and long-term. Determination of land capability class is done through a spatial approach by utilizing Geographic information systems. The study results obtained: 1) domination of the land capability class parameters: a) slope, > 65% area of 31.46%; b) drainage, either 94.2%; c) The volume of surface rocks, lots of 36.5%; d) the erosion was 49.7%; e) the soil depth in 66.6%; f) soil texture, subtle bit; sandy clay, clay 57.95%. 2) land capability class sub-watershed Riam Kiwa sub watershed Martapura III to VIII. 3) the direction of land use to control the flood vulnerability appropriate land capability.
