River Corridor Development towards Water Quality Preservation in UTM River

Abstract

UTM River water quality is decrease due to increase of human activities in land used. This research study is conducted to investigate the status of water quality and develop river corridor in UTM River. 7 sampling station are determined along UTM River, which is upstream, middle-stream, and downstream; where the water are test for 6 physico-chemical parameter namely DO, pH, BOD, COD, SS, and NH₃N. The water are analysis based on APHA 2005 that divided into two categories, in-situ analysis for DO and pH, and laboratory analysis for BOD, COD, SS and NH₃N. Result indicates UTM River is majority in class 1 and class 2. However, uncontrolled and unmanageable of rapid development in land used activities will possibility and probability to cause river water pollution to increase into class 3 and class 4. Therefore, the corridor concept has possibility to control and prevent from further pollution. Several suggestions could also be taken into account, namely maintenance plan, widening and deepening the river, improving existing corridor, cleaning the river, etc. Therefore, if the river corridor development could be achieved, then the UTM River are possible to be improve from continuous polluted.
