Abstract

Water supply and demand is one of the hot topics discussed in the community today. Higher growth rate of the population has drawn heavily on the natural resource base in Malaysia. Trend of supply and demand in the Langat catchment, water availability assessment and water storage capacity to supply and demand were investigated using a new accounting concept and analytical approach, Water Evaluation and Planning (WEAP) system. The assessment model is computed based on three scenarios—Scenario 1: Higher Population Growth, Scenario 2: Water Year Method and Scenario 3: Extended Dry Climate Sequence. The study found that Langat catchment is relatively sensitive to the growth of demands, suggesting that slight changes in population growth will alter the present water availability. Furthermore, the populations increase to 7 % with the increment of climate variation of the current condition, thus exposing the study area with water scarcity problem.
