For many years, during the monsoon period the River (Sungai) Terengganu catchment in Malaysia has been flooding and causing flood risk problems to the inhabitants as well as the environment. This study uses the realtime simulation in ArcGIS 10.3 and 3D in ArcScene 10.3, and the variables obtained from the soil and water assessment tool SWAT such as the land use, soil and slope are the parameters measured to induce the flood. the application of soil water assessment tool (SWAT) has produced the demarcation or boundary called delineation of the whole Terengganu watershed. When certain portions of the Hydrologic response unit HRU; land use, soil or slope is changed due to temporal adjustment and climate change, then the model can predict zones of low, moderate and high flood risk. The 3D simulations appear to produce a visual model for decision-making, planning, management, and mitigation. The simulation helps in determining the extent of the flood by using animation in ArcScence 10.3, to visualize the simulated flood water level.
A proper understanding of beach processes must include the adjacent shallow marine waters or nearshore environment. This paper focused on the sedimentological and morphological investigation of Terengganu coastal area stretch lies between Dungun and Kemaman. The study area comprised five beaches and 36 nearshore stations. The present investigation attempts to study the time variation of the grain-size along the coast and in order to observe one-year cycle of the perpendicular profile of the beach. Teluk Lipat beach faced a huge modification compared to other beaches. The severely-eroded beaches in the study area characterized by coarse sand. Sediments from backshore and upper beach zone decreased in mean size and became poorly sorted towards surf zone area. Meanwhile, superficial sediment distribution of nearshore area revealed that silt is the most dominant component and the sediment size became coarser towards the shoreline. The results favor an alternative explanation, indicating that the river is the main source for the coastal sands, which are probably reworked by longshore currents on opposite directions apart from the river mouth, resulting on coastal propagation.
Flood is one of the natural disasters that occurs mostly due to climate characteristics and locations. The application of SWAT has categorized the subbasins and identify them on the basis of parameters. The use of GIS technology produces the flood risk zone through the 3D ArcScene 10.3. the ArcGIS 10.3 and ArcSWAT 2012 were employed for the analysis of the result. The remote sensing data from ASTER DEM was also been used for providing the highresolution platform. One of the significance of this study is the identification of 25 different sub-basins with their individual parameters that make easiear to classify and explore. The 3Dsimulation produces different categories of flood risk zone from very high vulnerability of flood to no flood risk zone. All these are confined within the 25 subbasins parameters obtained from the catchment area of Terengganu. The model designed in this study is clearly going to be useful for planning as well as management not only in Terengganu but entire Malaysia or similar environment.
