| Summary: | Hydrological evaluation and sediment loading of the Chini Lake catchment was investigated. Sediment loads and water discharge from seven selected feeder rivers were measured over a period of one year (January to December 2006). Suspended sediment concentration was measured by the standard method. The annual rainfall from 1984 to 2006 at the Chini Lake catchment ranged from 1487.70 mm (1997) to 3071.40 mm (1994), with the annual rainfall for 2006 being 2544.50 mm. Stream flow rate during the sampling periods was relatively slow, ranging from 0.001 to 1.31 m3s-1 (or an average of 0.21 m3s-1). The highest and lowest stream flow discharges were recorded from the Gumum River and Cenahan River subcatchment. The amount of sediment load ranged from 0.49 to 166.02 kg/km2/day (or an average of 30.57 kg/km2/day) in the study area. The highest sediment load was recorded in the wet season and the lowest in the dry season. Human activities have significantly affected the hydrological functions and deposition of sediment and thus influenced the variation in sediment loading. |
