Abstract

Urbanisation is a dynamic process which involves the expansion of urban related areas with definite environmental impacts, one of which is the alteration of the urban micro climate including the frequency and magnitude of rainfall events. This article analyses the effects of urbanisation on the changing rainfall pattern of highly urbanised Kuala Lumpur. For the purpose of comparison, Mantin rainfall station was chosen to represent the area with the least urbanisation. The diurnal rainfall data for both Kuala Lumpur and Martin stations were collected for the 20 years period of 1981 to 2000. They were then divided into two extreme intensity categories viz. light and heavy rainfall. The overall results showed that the yearly average rainfall for Kuala Lumpur displayed an upward trend since 1990. This was different from the more fluctuating trend before the 1990 period. In conclusion, the Kuala Lumpur Cityhall would do well to heed this finding as an important hydrometeorological barometer, especially in reducing the frequent occurrances of flash flood in Kuala Lumpur. Not only must urban climate issues such as urban rainfall be included in the city's 'green' and sustainable development policies, but that more importantly such policies must be enforced in the subsequent course of Kuala Lumpur urban landscape planning.
