Abstract
Many small earthen structures were damaged by the Hanshin-Awaji Earthquake, while large-scale dams did not suffer serious damage. As dams near an epicenter must be inspected immediately after an earthquake, it is necessary to construct a dam information database in order to maintain a large number of dams efficiently to mitigate damage resulting from earthquakes. In this paper, I will discuss database system for irrigation dams of at least 15m in height.
