The Upper Citarum Watershed is an area that replaces the annual flood. The annual flooding experienced by the Upper Citarum watershed is influenced by several factors, such as changes in land use. From these annual flood events, there will be a level of loss experienced by communities affected by floods. Floods that occur in the Upper Citarum watershed can be seen from the results of the visual model of the upstream Citarum watershed, so that the information can be obtained on the areas affected by flooding and large floods from each affected areas. The purpose of this study is to determine losses due to flooding obtained from flood risk level data, which is the result of an overlay of the level of flood hazard and flood vulnerability. The level of flood hazard can be obtained from the processing of the digitized flood model and field survey. While the rate of flood returns is obtained from the processing of land use data which is the economic value of each land use. This research resulted in a level of flood risk which is dominated by a moderate level of flood risk of 44.15%, then the high-risk level is 42.25%, and the low flood risk level is 13.6%. The extent of the flood risk level is then converted to the economic value of each land use, to get the value of the loss rate. Determination the level of loss, in addition to taking into account the level of the parameters of flood risk, the extent of each region level of risk also influences the determination of the level of flood losses in the Upper Citarum Watershed. This research is carried out as an effort to develop disaster mitigation in the annual flood prone area tobe used as a reference in the development planning process.
