Determination of Catchment Area Using DEM Delineation in Bakri Drainage Network

Abstract

The flood disaster had been an issues for all country around the globe including Malaysia. This impact can be observed through the economic activities, social, environmental and psychology aspect. In this studies, the flood prone areas that had been investigate were at Bakri, Muar. The drainage system at Bakri, Muar had been observed and navigate by using the Unmanned Aerial Vehicle (UAV) for delineate the watershed. Then, the uses of online tools had fully utilized and practice in order to obtain the accurate output product which is watershed delineate. The online tools such as QGIS, Google Earth and GPS Visualizer had been adapt through the process of producing final output product. Thus, the QGIS plays an important role in in this studies to obtaining the accurate and reliable data for the watershed delineate.
