Flood is one of the most common hazards and the events have often occurred in the Garut Regency, which can cause loss of property and human lives. Eighteen-four sub-watersheds has divided The Upper Cimanuk Watershed based on three-order, selected as DTA01 to DTA84, for prioritization purpose. In this study a flood hazard model in Upper Cimanuk watershed is examined based on the morphometric aspect, combined land use analysis and the supplementary information regarding slope and rainfall. Each sub-drainage basin was ordered into grades based on the considered compound parameter (Cp). These results define the area flood hazard in prioritization map were divided into three zones: high, medium and low classes. Three distinct measurements such as basic, linear (Rb, Dd, Lof, and T), and shape (Re and Rf) aspects obtained the morphometric characterization over the 84 sub-watersheds. The prioritization results based on the connection of morphometric aspects and land use only 12 sub-drainage basin considered as First priority, 9 sub-watersheds considered as medium and 5 sub-watersheds considered as low priority. The result of this study can exact the action to fix the possible hazard from floods in the study area.
