To study the impact of urbanisation on water quality of a river: a case study Sg. Damansara, Petaling Jaya / Anding Unchi

The process of urbanisation is invariably accompanied by great changes to the natural landscape, with consequent impacts on the hydrologjcal processes. As the original pervious and rough natural ground surfaces are being transformed into less permeable and smoother paved-up areas, rainfall abstraction losses due to infiltration and depression storage are reduced, resulting in an increase in the vollume of surface runoff. As a result this will increase the volume of pollution discharge to the river water course as urban runoff. This thesis presents analysis on the potential impact of urbanisation on water quality of a river in Malaysia, This thesis is a case study of Sg. Damansara in Petaling Jaya. This river is being selected as a case study since it is situated at centre of development and urbanisation. This study results win be necessary in order to identify the standard of water quality of Damansara river. Water samples are taken from various point along the river. The samples are analysed based on the selected water quality parameters to identify the degree of water quality.
