The purpose of in this study to develop of the dam safety management assessment tool based
risk assessment for the dam safety management paradigm shift. As the purpose of the dam safety management
assessment tool is to develop the next generation dam safety management decision-making support system.
Traditionally dam is considering non-risk structure, however recently natural disasters and the risk components
are increasing. So, there has been increased interest for the dam vulnerability. Accordingly, the risk components
of the dam are carried out systematically organized and analyzed. Directly on structures major load, such as
floods and earthquakes, the probability of failure and the system response probability for the theoretical and
analytical method are described. Therefore in this study is to develop hydrological and geotechnical analysis
module and risk analysis and assessment tool for the development of the dam safety management decision-making
support tool D-SMART. Analysis module is composed of two parts. One is the initial load probability result
part to the hydrological and an earthquake characteristic, the other is system response probability result part.
Risk analysis and assessment tool is composed of the based event tree analysis method. In this year, risk
assessment tool is developed β-version with basic framework. It is including analysis module, development
algorism of risk analysis and assessment based MS Excel add in. In the future, is planning to develop a
separate program for enhancing practically.
