Application of pcswmm for the 1?d and 1?d�2?d modeling of urban flooding in damansara catchment, malaysia
Coupled with climate change, the urbanization?driven increase in the frequency and intensity of floods can be seen in both developing and developed countries, and Malaysia is no exemption. As part of flood hazard mitigation, this study aimed to simulate the urban flood scenarios in Malaysia�s urbani...

Coupled with climate change, the urbanization?driven increase in the frequency and intensity of floods can be seen in both developing and developed countries, and Malaysia is no exemption.

The flood simulation was performed using the Personal Computer Storm Water Management Model (PCSWMM) modeling of the Damansara catchment as a case study. An integrated hydrologic?hydraulic model was developed for the 1?D river flow modeling and 1?D�2?D drainage overflow modeling.
