| Summary: | In recent years, monitoring quality of water body or reservoir has become a
main concern for the determination of current condition and long-term pattern
for future management. This study focused on hydrology properties and water
quality of Sembrong Dam in Johor, Malaysia. The Sembrong dam reservoir
is constructed on large lowland rivers with gradually sloping banks, it can be
characterized by inundation of large areas, extreme horizontal variability with
extensive shallow riparian vegetation and shallow reservoir. The secondary
function of the dam was to provide a clean water supply to 240,000 consumers in
Kluang district area were used for daily activities. Extrapolation beyond the data
is often necessary to provide information needed for dam safety risk assessments.
Thus, quality of the water from Sembrong dam important for future. The rainfall
data were sourced from the Environmental Impact Assessment (EIA) report
and the Department of Irrigation and Drainage, Malaysia whilst reservoir inflow
data were extracted using a water balance equation. For water quality study,
there were a total of 17 water quality sampling stations. The result indicated
that Sembrong River Dam slightly shows high soil loss (487.12 kg/km2/day)
where is consist of soft fine grained silty clay material with organic matter, tree
roots and decaying timber. For rainfall and evaporation records are 1862 mm
and 1098 mm. Sembrong River (Zone A) generally slightly polluted compared
Merpoh River (Zone B) where is clear from pollution in Sembrong Dam. Due to
Biological parameter where the Sembrong River shows a high of Total Coliform
rather Merpoh River. The chemical parameters show that Sembrong River was
not a good condition. According to Water Quality Index, Sembrong River
was truly slightly polluted compared Merpoh River in Sembrong Dam. As a
conclusion, Sembrong dam categorized as Class III according to NWQS |
