| dc.description.abstract | The main purpose of this study is to assess landslide hazard zones for Jima Geneti Woreda using Geographic Information system (GIS) and remote sensing by applying multi criterial analysis. The causative factors considered to landslide analysis in the area was, slope, aspect, drainage density, lineament density, geology, land use land cover and soil type. The thematic data layer representing various factors were, generated by using GIS and remote sensing techniques. Using Analytical Hierarchy Processes the weight of each factor were calculated and assigned in GIS. To add these factors and produce landslide hazard map weighted linear combination was, used. Landslide hazard map prepared was, categorized in to very high, high, low and very low hazard zone. The result of analysis were verified using landslide inventory data. The result showed that the landslide hazard map agreed with areas that had recently experienced landslide and using this mode was very suitable in predicting landslide hazard and generating landslide hazard maps. The landslide hazard map shown that southwestern region of study area was prone to landslide. The correlation between landslide occurrence and causative factors was, correlated to examine their relationship. Based on landslide hazard zone various mitigation measure was, taken for stabilization of unstable slope. The present study determine that multi criterial analysis with GIS is a powerful tool in predicting landslide hazard mapping in the area. The future landslide hazard analysis and landslide intervention in Jima Geneti Woreda suggested for further researcher, land management and concerned body should have based on the present finding | en_US |
