| Summary: | Wateros considered as one of the most important componentmf the ecosystem. The
conditions of the water resource within and flows through the drainage systems of
the Similajau National Park determine the long~term ecological intergrity of the
Park. The appropriate planning approach and desired management interventions
must be designed and aligned towards the maintenance of envirmUllent water
quality requirement for sustainability of the overall ecosystem functions.
A study was undertaken from the month of May to August 2001 to characterize the
watershed geomorphology and hydrology of the Sebubung and Seroba Watersheds,
and assessment of water quality of the two rivers namely Sebubung River and
Seroba River. The rivers flow through the Park prior to discharging their waters
into the South China Sea. The upstream and the headwaters of the two rivers lie
outside the Park, one within the newly established oil palm plantation and the other
logged over area, respectively.
Thirty water samples were collected and analyzed for Total Suspended Solids
(TSS) Suspended Solids, Total Coliform, fecal Coliform, Biological Oxygen
Demand (BOD), Chemical Oxygen Demand (COD), and Nutrients (Ammonical
Nitrogen and Phosphate). In~ Situ measurements for Dissolved Oxygen (~O),
Temperature, pH, Total Oisolved Solids (TDS), Salinity, Oxidation Reduction
Potential (ORP), and Turbidity were conducted at eight sampling points, five along
Sebubung River and three along Seroba River.
This study indicates that the TSS, Turbidity, BOD, and COD of the water of
Sebubung River whose upstream zone and head waters currently under active
establishment stage of conversion to oil~palm plantation, exhibited higher mean
values relative to the water of Seroba River. Mean TSS and Turbidity under low
flow recorded at sampling points WSB I 158.67 mg/L, WSB3 188.67 mg/L, WSB5
52.0 mglL, and WSB6 72.0 mglL. However, comparative analysis between water
quality of Sebubung River and Seroba River indicated that only turbidity and TSS
were significantly different at 95% confident level. |
