Mapping of risk index is starting step before we take an action to reduce flood. Risk index map is analyzed by using hazard, vulnerability, and capacity index. Hazard index is analyzed by some parameters, there are depth, frequency, and flood duration parameter. Then flood map is get by result of HEC-RAS modelling. Capacity index is analyzed base percentage of well drainage. Then risk index can be analyzed base of equation in PERKA BNBP No. 2 in 2012.
