Field determination of runoff coefficients for differrent urban conditions in the humid tropics / Zolkefli Zakaria

This project is about an urban hydrology study in Taman Mayang subcatchment. The main aim of the project is to obtain the field runoff coefficients for different urban conditions in the humid tropic, such as open spaces, residential and commercial. Taman Mayang is chosen for this study because it is a fully developed urban area with mixed development setup primarily housing and some commercial activities and also some opens spaces. These activities may represent the required setup necessary to determine field runoff coefficients under different urban conditions. The study area is also equipped with required instrumentation necessary to carry out field measurement. Rainfall and streamflow data needed for this project are either obtained from direct measurement in the field or obtained from Drainage and Irrigation Department (DID). Field measurements are organized to represent storm events but in most cases field measurement cannot be conducted due to dry weather condition. The finding of this study are very useful because the runoff coefficients obtained can be used to verify the values used by many engineers in Malaysia to design urban drainage system
