Abstract

Abstract Sintang Residence is a region which has susceptible region of natural disaster mainly landslide and flood. As the result of that vulnerability, it is needed to do the research to determine zonation of susceptibility of disaster. Zonation of landslide is based on four parameters such as slope, annual rainfall, geology factors and land use. Zonation of flood is based on monthly/daily rainfall, land use, topographic condition and flood terrains. Based on secondary data and primary data, Sintang residence can be divided into three susceptibility landslide zones, i.e. intermediate, low and very low susceptible landslide zones. Susceptible flood zones are divided into three zones i.e. high, intermediate and low susceptible flood zone. Landslides in that area are happened due to some factors; among other things are the rocks weathered, high slope direction and no retaining wall. Flood is happened mostly due to the position of residences which straight forward or less height toward river water level and that location near with the rivers. Flood occupied the residences mostly pass terrain edge river or pass by Sub River or rubbish ditch that ended in the main river. The purposes of mitigation those disasters based on the land use Keywords : flood, landslide, geographic information system
