Abstract

The paper describes the use of spatial analysis on Geographical Information System (GIS) in analyzing the impact of flash flood to the properties damages. Flood is a natural disaster in this country and many other parts of the world. Flood damages/losses is essential for the flood victims for insurance claiming purposes. For the authorities it is also importance n order to decide whether the flood mitigation of the affected area is worth spending. The common practice of flood damage estimation was through ground survey, which was very laborious and time consuming, where usually it would take around several months to years to complete the survey. Onthe other hand GIS technology would provide alternative method of such flood damage estimation through its spatial analysis capable features. This study was conducted at Kg. Melayu Subang and Taman Subang Jaya, at the outskirt of KualaLumpur, Malaysia. These two areas which are located in the river basin of Sg. Damansara and are prone to flash flood. The parameters applied for the estimation were average hous hold belonging, number of houses or offices, number of infrastructures involved and flood Annual Recurrence Interval (ARI). GIS techniques of overlaying, intersecting layers, spatial analysis and attributes matching with layers have been used in this the analysis. The estimated value of the flood damage derived from this method is comparable to those estimated by conventional method but cumbersome ground survey method. Hence, this study has revealed an alternative method that could provide faster flash flood damage estimation.
