摘要
The DID （Department of Irrigation and Drainage） in Malaysia has produced a manual on urban stromwater management specifically for the Malaysia region with usage of infiltration method towards controlling the quantity and quality of surface runoff. With this method, the volume of surface runoff can be reduced and flood problems in major cities can be eliminated. The study areas of Sungai Kedah ungauged catchment are located at the northern region of Malaysia. The Kota Setar sub-catchment is located at the downstream of Sungai Kedah with the newly completed development of control barrage at the upper Kota Setar. This paper will describe the analyses of the infiltration curves at Kota Setar. The resulting infiltration maps have developed based on the infiltration capacities.
