In maintenance of hydropower station, adequate management of unstable slopes surrounding the hydropower station equipment is one of the important subjects. It is necessary to correctly grasp the slope condition of the collapse and landslide around the hydropower station equipment, and moreover, it is asked for a quick action from a new collapse, which occurs suddenly. Although such management of a slope was performed by the inspection check by the engineer engaged in the observation and the everyday maintenance business by the meter etc., in order to perform this efficiently and effectively, the slope management database system, which used Web-browser, was developed. This system can be used if the software as which Web-browser, PDF, and CAD file are regarded is contained in the personal computer. The data of each slope consists of a slope chart, photographs, and previous investigation and measurement, aerial photo interpretation result, publication geologic maps of the slope circumference etc., and can be accessed these data now from a map top or a slope table. Moreover, renewal of data after inspection check shall also be easily performed in the maintenance spot so that the newest information on a slope can always be grasped. This system uses the Internet technology and enables system development and maintenance at low cost.
