Review of a Green Infrastructure Approach in Urban Flood Management and Its Possible Application in Binh Duong Province

Abstract

Green Infrastructure (GI) is a concept that incorporates vegetation, natural processes, and land use into the built environment. This concept is considered an effective intervention for stormwater runoff minimization in urban flood management. In the context of increased flooding in many Vietnamese cities, the paper has carried out an overall review on GI, its advantages and constraints in urban flood management. Then, it tried to identify possible applications in the urban areas of Binh Duong province. The literature review shows that GI can bring many positive effects, such as reducing stormwater runoff, improving water quality, mitigating the impacts of climate change, and maintaining healthy and sustainable communities. However, the practical utilization of GI in urban flood management is still overwhelmed by traditional gray infrastructure such as roads, drainage pipe networks, and sewage treatment or water treatment systems, etc., which generally offer low sustainability, as shown in the literature. The main reasons are the uncertainties of GI hydrological performance, service delivery, and lack of appropriate decision-making supports for its multiple-benefit assessment. A review of the current situation on policy, authorities, and community awareness, along with the natural conditions of Binh Duong, was proposed to define the possibilities for applying GI in the province. There is a need for further studies on the technical deployment of GI solutions through experiments, methods, and tools for their performance assessment compared to the traditional gray solutions.
