Flood maps are a vital tool to provide various valuable information for reducing flood damage and spatial planning purposes. Only the flood risk map provides the consequences information of flooding, which used as a primary tool to initiative a holistic flood risk management project. Geospatial data such as satellite image and LiDAR data as well as hydrological data are used to produce flood maps with using integrated one and two dimensional hydraulic model. Risk is a production of hazard and vulnerability. Flood Risk is expressed as loss in term of monetary and flood risk zone for quantitative map and qualitative map, respectively. Three different depth damage functions were adopted to estimate the flood damage for three different physical elements. The average flood damage for residential areas is RM 350/m2, RM 200/m2 and RM 100/m2 using United States, The Netherlands and Malaysia damage functions. This study successfully produces flood risk but further study is needed for improve the results.
