Development of spatial similarity-based modeling to support integrated lake water quality management: recreational lakes in Klang Valley, Malaysia

Due to recent climate factors which lead to long dry spells and affect normal water distribution from the reservoir, there is a high potential for tapping water from recreational lakes as a resource alternative for high population density states in Malaysia such as Selangor and Kuala Lumpur. The cha...

Anthropology. Recreation Due to recent climate factors which lead to long dry spells and affect normal water distribution from the reservoir, there is a high potential for tapping water from recreational lakes as a resource alternative for high population density states in Malaysia such as Selangor and Kuala Lumpur. The challenges, however, are due to severe data limitations, no formation of a regular water quality monitoring programme and segregated catchment planning. This paper intends to discuss the application of similarity- based modeling as the alternative technique for integrated lake water quality management under the circumstances of severe data limitation issues and a limited programme of continuous lake water quality sampling and monitoring.

The majority are in class three of medium water quality status, with only four lakes considered as having a good condition of water quality and the remainder of thirty-five lakes are considered to have poor water quality.
