摘要：Landslide, debris flow, snow-slide arise every year in Japan, and precious property and life have been lost. Ministry of Construction and local government of Japan hurry up the installation of the sand control facilities ,for example soil saving dam, by the sand control plan in order to prevent the disaster. However, it is also necessary to consider the natural environment, when soil saving dam is constructed . The purpose of the research is that management and sand control plan of the sand control facilities simulates by using the Geographic Information System(GIS). On the simulation, digital map data which could cheaply and simply obtain was used. Enormo us funds are required they in that 1/500 vector data (contour line) are made. It is one of the reason why we starts the rescerch. In the study, the following data were used. There are digital map data of 50m mesh (elevation) and 1/25000 raster maps. One of the reasons for utilizing digital data is because there is a prediction that will come to be able to utilize the high resolution satellite data in the near future. As a result of the simulation using the 50m mesh data (elevation), transferable sediment and transportable sediment were more dangerous than actual plan. Sedimentary depth of the average calculated by the 50m mesh was very small value. By this receiving result, we made 10m mesh data from 50m mesh data. The most remarkable result of the research is to obtain vector data of the contour line from 50m mesh and original 10m mesh digital data. It is possible to estimates that number of soil saving dam and constructing place automatically decide using the geographic information system, when developed algorithm is used
