Application of 3D GIS flood simulation to investigate the source of inundation at Pekan sub-district

Flood is usually caused by heavy precipitation that eventually lead to river spillage. In some rare cases, inundation could happen due to the accumulation of water on land cover resulting in stagnant flooding. Pekan sub-district is chosen as the ideal study area to determine the type of flood in thi...
