Description
Summary:The purpose of this research is the use of a Digital Elevation Model (DEM) was used in conjunction with a Geographic Information System to compute morphometric factors influencing flooding vulnerability. These causal factors were subjected to a weighted overlay analysis in order to categorize areas based on their flooding vulnerability. The research location is in Sitiarjo Village Malang District East Java Indonesia. The flood disaster that most harmed the community in Sitiarjo village occurred in 1983, 2003, 2007, 2010, 2013 and 2017. Sitiarjo village is crossed by two major rivers, namely the Panguluran river and the Mbambang river which meet at the river in the southern part of the village.. The results showed that the flood vulnerability of sitiarjo village has a high level in the center of the village (flood plain and fluvial landforms). The greatest flood hazard is at the bottom of the confluence of the Pangluran and Mambang rivers in Rowo Terate Sub Village.
