摘要：
The paper discusses the sediment balance and transport characteristics of an urban river basin in the humid tropics -Kelang River, Malaysia. Soil erosion, estimated by dividing the basin into sectors and using the Universal Soil Loss Equation to calculate erosion in each sector, was found to range from 0.04-114.6 tonnes/ha/yr. Suspended sediment yield, estimated in 13 sub-basins using sediment rating and flow duration curves, was found to range between 165-2283 tonnes/km2/yr. The specific erosion in the sub-basins was calculated to range from 656-5,961 tonnes/km2/yr. The study also revealed that the sediment delivery ratio ranges from 27-45%. Sediment delivery ratio regressed against basin area and relief-length ratio resulted in both a negative and a positive correlation respectively. Sediment balance of the basin also indicated that a small percentage of the sediment is stored within the channel system.
