(2015). A GIS-based water quality model for sustainable tourism planning of Bertam River in Cameron Highlands, Malaysia. Environmental Earth Sciences, 73, 6525-6537.https://repoemc.ukm.my/handle/123456789/1598Cameron Highlands is experiencing rapid development as a popular tourist destination in Malaysia. This causes a rapid boost in construction and other tourism-related activities, such as the growth of vegetables, fruits and flowers. Due to that, the water quality of rivers in the highlands has been adversely affected. In this study, Bertam River, as one of the main streams in Cameron Highlands, was monitored to assess its suitability for recreational activities and conservation. Seven sampling points were selected in the river and tributaries: dissolved oxygen, biochemical and chemical oxygen demands (BOD and COD), total suspended solids (TSS), ammonia nitrate (NH3-N) and pH were measured and the water quality index (WQI) was computed during high and average water flow.enRiver recreational useSustainable developmentWater conservationWater quality index (WQI)Journal
