of LoL predictions of the raster method will be calibrated by the empirical equations of regression results from the number of catastrophic collapse events in Indonesia and the world. If the results are not significantly different, then the prediction of the amount of LoL can be considered close to and can be an additional reference in risk assessment in the Modified ICOLD method. 3. RESULTS 3.1 Basic Map Preparation The base map is a spatial data that is important in the final decision-making process. The completeness of the base map will have an indirect effect on the final result to be obtained. The basic map used in this paper is the result of running simulated dam and software with ZhongXing HY-21. For example used dam break innundation map at the Cacaban Dam in Central Java, Indonesia.
