A Study On Rainfall-Runoff Characteristics Of Urban Catchment Of Sungai Kerayong.

Abstract

Tadahan Sungai Kerayong telah dipilih sebagai tadahan kajian bandar untuk mengkaji proses penjanaan air larian di bawah pengaruh iklim topika. Tiga objektif kajian telah ditentukan; pertama, untuk menghasilkan perhubungan antara hujan dan air larian menggunakan kaedah regresi linear; kedua, menentukan peratusan permukaan tidak telap dan dibandingkan dengan keputusan daripada perhubungan hujan-air larian, dan ketiga untuk menganggar masa tumpuan air. Sungai Kerayong catchment was selected as an experimental urban catchment in order to study the runoff generation processes in tropical climate. The study sets three objectives, the first is to establish a reliable relationship between rainfall and runoff; the second is to estimate the percentage of impervious surface and compared the estimate with result from the rainfall-runoff correlation, and the third objective is to estimate the time of concentration of the catchment.
