Flood inundation modelling in the Kuantan River Basin using 1D-2D Flood Modeller coupled with ASTER-GDEM

Topography dataset is an important input in performing flood inundation modelling. However, it is always difficult to obtain high resolution topography that provide accurate elevation information. Fortunately, there are some open source topography datasets available with reasonable resolution such a...

As a conclusion, ASTER-GDEM can be used as one alternative topography datasets for flood inundation modelling.
