A study of river flow in Kerteh River, Terengganu using arcview soil and water assessment tool (AVSWAT)

Abstract

The area for this study is Kerteh River catchment area that located at Kemaman, Terengganu which have the total area of the watershed is approximately 27 500 hectares. The catchment area consists of rural area, urban area, agriculture area and industry area. The industry activities and the behavior of urbanization bring much strain on utilization of land and river system in Kerteh River catchment. Oil and gas industries area that nearby the catchment area give a significant impact on the generation of runoff and other water fluxes, pollutant transport to water courses and rates of erosion. The main aim of this study was to determine the river flow rate of Kerteh River catchment area and to create a new model of river flow simulation of Kerteh River. The study was done by using in-situ sampling where a current meter was deploy in two sampling station to get the data of flow in Kerteh River. This study also needs the Soil and Water Assessment Tool (SWAT) to predict the impact of land use on water flow. The SWAT model were simulated the watershed process for IO years (2000-2009). The correlation analysis is being analyzed from the In-situ data and data from A VSWA T. The analysis show that the good relationship which is 0.91. This model is very important for study and predicts the river flow in the future.
