Abstract

The purpose of this study is to generate and evaluate the landslide hazard map for Gua Tempurnng area using Geographical Information System (GIS) and remote sensing techniques. GIS mapping is generated and integrated with landslide potential database in order to construct landslide hazard map. Landslide locations were identified in the study area from imagery and aerial photograph interpretations followed by field surveys. The topographic and geologic data were collected, processed and created into a spatial database using GIS and image processing. Factors that influence landslide occurrence at the study area was identified and analyzed based on literature review, landslide history and field observation. Data acquisition for factors such as slope gradient, slope aspect, slope curvature, river and landuse were retrieved from topographic database. Data acquisition for rainfall intensity vegetation coverage, mineralogy and lineament were retrieved from remote sensing database. The image processing task will be performed using Adobe Photoshop while the analysis and map generation process will be carried out using ArcGIS and ERDAS Imagine software This project is vitally required in order to avoid any possible landslide occurrence and to determine the safety level for any development along the terrain slope. Landslides embodied one of the major geological hazards that cause losses in lives and property. The natural condition of the hilly side such as steep slope, poor consolidated loose soil and water movement have tremendously induce landslide occurrence. Its occurrence can be triggered and accelerated by human activities such as land development and deforestation. In recent days, the increasing development of recreational and residential area along the slope terrain and continuous development at hilly side have increase the unstable soil condition. along the hill slope. This phenomenon will increase the potential of slope failure that can cause major disaster in expense of life and property losses. This project can identified potential landslide areas thus prevent any insignificant land development, accident and negative consequences at the study area.
