| Summary: | Suspended sediment yield from Sg Chini, which is one of the active feeder river in Chini Lake,
Pahang was studied for two different seasons, namely the normal and rainy seasons at three
selected stations. In this study, the data was observed on 16/08/08, 31/08/08 and 13/09/08 which
representing normal season, while 4/12/08, 25/12/08 and 25/01/09 are rainy season. Two
parameters were measured at each station, namely the river discharge (Q) (m3/s) and sediment
concentration (mg/L). The result shows that, the estimation of Q values for normal day ranged
between 48,608,640 L/day, 86,875,200 L/day and 95,264,640 L/day. Meanwhile during rainfall
season, the Q estimation ranged between 66,795,840 L/day, 381,801,600 L/day and 300,888,000
L/day. Average of suspended sediments concentration (SSC) based on three sampling stations
show different values for the two different seasons. The sampling on 16/08/08 indicates that average SSC is 17.2 mg/L, 42 mg/L and 22.4 mg/L, on 31/08/08 was recorded 32.8 mg/L, 37.6
mg/L and 36.8 mg/L, 17.6 mg/L, 38.4 mg/L and 38.8 mg/L was recorded o 13/09/08. Meanwhile,
the SSC during rainfall is 28.8 mg/L, 56 mg/L and 71.2 mg/L was recorded on 4/12/08, while the
sampling on 25/12/08 indicates that the average SSC is 21.6 mg/L, 19.6 mg/L and 39.2 mg/L, and
also 20.8 mg/L, 42.8 mg/L and 36 mg/L on 25/01/09. When converted to the average suspended
sediment yield in term of square km, the estimation value for suspended sediment yield that
transported from Chini river is 20,984.52 kg/km2/year (20.65 tonnes/km2/year) during normal day
and 86,248.68 kg/km2/year (84.88 tonnes/km2/year) during rainfall |
