GEOSPATIAL ANALYSIS OF HYDROLOGIC RESPONSE UNITS OF FLOOD INUNDATION AT DIFFERENT SUB-BASINS PARAMETERS IN TERENGGANU WATERSHED, MALAYSIAhttps://keffi.nsuk.edu.ng/handle/20.500.14448/4606Flood is one of the natural events in our environment. It destroys and displaces naturally existing structures found within the Hydrologic Response Units (HRUs). These include the Land Cover/Land use, Soil structure and the topography or the terrain. The method applied was the used of ArcSWAT to determine those flooded sub-basins by simply delineating the whole watershed into different sub-basin parameters. The result proves that what determines the flood influence was the area of the sub-basin that contained the HRUs not the HRUs itself. Once the sub-basin was inundated, the flooded streams within the sub-basins were calculated as flood impact, in this analysis 5 number of sub-basins were flooded in the watershed of Terengganu. Sub-basin number 3 has the highest flood impact with 14,699 hectares and sub-basin number 5 has the lowest total flood impact of 968.82 hectare.enFlood Impact, Inundation, Sub-basins, HRUs, WatershedArticle
