Abstract: he application of 3D GIS has enabled better representation and visualization of flood events than previous 2D maps. Flooding is common in the Terengganu basin. Flash floods occur most of the year during the monsoon season, which lasts from November to January. Flooding along riverbanks is mainly affected by heavy rainfalls of 2500mm to well over 3500mm per year. This has significant impacts on environmental resources such as land use/land cover, local soil types and slopes. The study area of Kuala Terengganu was particularly affected by heavy rains and flash floods during the monsoon season. ASTER DEM resolution 5m converted to ArcScene 10.3 using ArcGIS 10.3 and 3D software. In recent years, flood monitoring methods have been developed that can predict water flow and associated risks and hazards. 3D visualization techniques include remote sensing such as satellite imagery and geographic information systems “GIS”. and LiDAR modeling
