Abstract

This study was performed to estimate surface erosion and suspended yield in the forested catchment of Sungai Anak Bangi using USLE and numerical analyses from September-November 2006. The value of erosion rate, as dominated by Serdang and Prang series is moderate at 84.88 tons/ha/yr. Meanwhile, three major data were measured namely the rainfall depth, the suspended sediment concentration and river discharge (Q) at two sampling stations along the river. 12 rainfall events were recorded with highest rainfall of 36.7 mm was received on October 02, 2006 while the lowest rainfall depth was recorded on October, 08, 2006 (1.9 mm). Almost all the rainfall events occurred within the short and moderate durations (< 7 hours). Meanwhile, the daily Q sampled range from 172.8 m3/day to 6220.8 m3/day or 172, 800 and 6220, 800 L/day. The average suspended sediment concentration values recorded for both stations are considered low with 19.47 mg/l and 25.23 mg/l were recorded at Station 1 and Station 2, respectively. When converted to average suspended sediment yield per day, Sungai Anak Bangi was recorded of 75.0415 kg/day at Station 1 while at Station 2 was 103.256 kg/day. When converted into per square km, the gross value of suspended sediment yield leaved from Sungai Anak Bangi is estimated about 27.907 kg/ km2/day or 10, 186 kg/ km2/yr-1.
