Abstract

Development plans for new cities will be held in the Walini area, Cikalong Wetan District, West Bandung Regency. The purpose of this study is to provide geological information, engineering geology and re-evaluate the development location a new city based on a map of engineering geological capabilities. The research methode used is collected the physical properties in field includes soil / engineering properties, geomorphological conditions, geological structure and depth of groundwater level, then collected maps of geological disaster and landuse maps, the preparation of engineening capability map is carried out by weighting and overlaying maps in ArcGIS. Based on geomorphological conditions, the study location is consists of volcanic landforms (30 - 90) and steep structural hills (170 - 270). The engineering geological unit of the study location is divided into intercession of sandstone-claystone, breccia, gravel sandstone and clay silt units. The depth of the groundwater level ranges from 5 m - 20m. Geological disaster maps are used to support the preparation of a engineering geological capability map which include a vulnerability map of soil movements, earthquake vulnerability maps, volcanic hazard zones and flood vulnerability maps. The zone of technical geology capability at the study location consists of very low, low, medium and high engineering geological capabilities zones.
