| Summary: | One of the most important elements in developing an area is a reliable water supply.
In Pulau Sebatik water supply is an essential and critical issue as there is not enough
water supplies to fill the demand for the settlers there. A study was carried out to
assess the water resources at Sungai Pendikar to find another reliable water supply for
the settlers in the island. All the sub catchments and major rivers in the island were
demarcated and the land covers were classified. Analyses of water quality and water
quantity were done at three water sampling stations based on their land cover classes.
Fourteen sub-catchments were successfully delineated from the topography map ad
six different land cover classes were classified from Landsat TM 2003 satellite image
which are: (i) bare lands. (ii)degraded forest and scrub, (iii) large scale agriculture,
(iv) primary or largely undisturbed forest. (v) rural areas and (vi) wetland-undisturbed.
The length of Sungai Pendikar is 59.97 km with the total acreage of 1930 hectares.
Station 1 which (wetland-undisturbed) and station 2(degraded forest and scrub) are
classified under the class III which defined as water supply with extensive water
treatment, aquaculture of tolerant species and livestock consumption. Station 3 (large
scale agriculture is classified under class IV and categorized as irrigation. All of three
stations are having low discharge estimation and enough for the settlers in Pulau
Sebatik. The results of the study determine that the water resources at Sungai Pendikar
are reliable as the water supply for the settlers with extensive care of the water quality. |
