| الملخص: | The Sungai Sarawak Regulation Scheme (SSRS) is the ftrst of its kind in South East Asia
and could be one ofthe very few "three in one" infrastructure-combining barrage, lock and
bridge. This scheme aimed to improve and maintain the water quality to the quality
standard acceptable as a reservoir for water supply for Kuching City and its surrounding
areas besides improving the aesthetic value of the river. The effectiveness of SSRS as a
tool for water resource management in Kuching area was evalu~ted by comparing the
water quality data ofthe pre~barrage era against the post~barrage e~. The data were tested
first for nonnality by using One~Sample Kolmogorov Smimov test followed by a
descriptive statistics, ANOVA (analysis of variance), Paired Samples T-Test and Trend
Analysis. This study concluded that the installation of the barrage across Sarawak River
has brought about significant improvement to the dissolved oxygen (00) levels,
biochemical oxygen demand (BOD) levels, salinity, turbidity and the bacteria counts, to
the section of the river upstream of the barrage. Other water quality parameters such as
chemical oxygen demand (COD) and ammoniacal nitrogen (NH3~N) were deteriorated
after the installation. |
