ABSTRACT
Through the a combination of social survey and numerical modeling, this chapter aims to evaluate the applicability of Sustainable Urban Drainage Systems (SUDS) in Ho Chi Minh City as adaptive measures for inundation mitigation as well as urban environment improvement. In order to obtain the preference of local people for SUDS solutions, face-to-face interviews were conducted using questionnaires. The chapter considers four types of SUDS: Rainwater Harvesting, Green Roofs, Urban Green Space, and Porous Pavements. The survey revealed that different opinions regarding the desirability of various SUDS options. Interestingly, the model simulation results gave different assessment for SUDS. More specifically, Green Roofs and Urban Green Space are the best technologies followed by Pervious Pavements and Rain Water Harvesting. By changing the concept of handling storm water from a nuisance to an utilizable resource, not only can the flooding problem be solved, other benefits also can be captured. This mind-set change is where the concept of SUDS emerged.
