LAND SLIDE ANALYSIS USING DIGITAL ELEVATION MODELS

Landslides almost every year occur in Indonesia, this rare landslide that can be detected early. because so far the prediction of slope slope is difficult. To predict the calculation requires the analysis and stability of the slope manually. This manual calculation process is quite long and long process. The calculation data and slope stability analysis are in the form of slope measurement, the work is quite tiring and risky for the researcher, and also the scope of the slope that can be measured is only narrow. In addition to slope inclination data, for slope analysis also requires soil data to be sampled and testing in a geotechnical laboratory. This study investigated slope stability by creating landslide models using Digital Elevation Models (DEM), and Geoslope programs. Slope model was analyzed from DEM and landslide stability analysis using Geoslope. From this concept we are expected to analyze landslide / stability slope quickly and accurately without risk for researcher. The results of lab tests were obtained:water content (wN), wN1 = 39.47%, wN1 = 40.54%, wN1 = 38.89%.
