2004 UC Proceedings Abstract
 Preparation of Geotechnical Database of Mountainous Cities With ArcGIS Track: Environmental Management Author(s): Binod Tiwari, Binod Tiwari, Hideaki Marui, pankaj Bhattarai, Kiyomichi Aoyama, Gyanu Tuladhar ArcGIS was used to make existing landslide distribution maps of three towns in Niigata, Japan. Soil samples were collected from highly weathered and unweathered rocks of various geological formations to measure the variation in friction angle, consistency limits and mineralogical composition. Those point data were useful to distribute the soil strength throughout the area using DEM, prepared from high resolution scanning of topographic maps, soil strength and estimation of ground water distribution pattern based on the piezometer information. An automated 3D slope instability map was prepared based on the safety factor values and compared with the existing situation.
