Abstract

Water quality in Cameron Highlands has significantly diminished due to agricultural activities. This research aims to analyse water quality in the urban and agricultural area by conducting water sampling and in situ analysis. Water quality index (WQI), total nitrogen (TN) and total phosphorus (TP) were calculated and compared among different areas. Results for WQI shows that water quality at W7 deteriorates at class IV (33.5) compared to class II for another agriculture area. Meanwhile, another results showed that the WQ_02_AG transported significantly higher (14.9 mg/L) loads of TN than the urban area, but the phosphorus load was considerably lower (1.58 mg/L). Results for the urban area are slightly polluted and unsuitable for recreational purpose. In agricultural areas, water quality deteriorates due to sediment transport and nutrient infusion caused by agricultural activities. Therefore, powerful agricultural management practices for effective reservoir sedimentation management as one of the non-structural measures are recommended.

金马伦高原水库有效沉积管理的城市水质趋势分析

由于农业活动，金马仑高地的水质明显下降。本研究的目的是通过对城市和农业地区的水质进行采样和原位分析。计算并比较了不同区域的水质指数(WQI)、总氮(TN)和总磷(TP)。WQI的结果表明，与另一个农业区的II级相比，W7级的水质在IV级(33.5)恶化。与此同时，WQ_02_AG的TN转运量显著高于市区(14.9 mg/L)，而磷转运量显著低于市区(1.58 mg/L)。市区的污染程度较轻，不宜作娱乐用途。在农业地区，由于农业活动引起的泥沙输送和养分输注，水质恶化。因此，建议采取强有力的农业管理措施，作为有效的水库沉积管理措施之一。
