Sustainable Urban Drainage System (SuDS)

Potential climate/ disaster impacts addressed by approach & Justification for approach:

The climate in Dong Hoi is characterized by hot and dry summers, followed by periods of heavy rainfall and tropical typhoons. When rainfall is unable to infiltrate into the ground, runoff water accumulates in low lying areas, which frequently results in large-scale flood events and localized, short-term flooding of infrastructure. The large extent of sealed areas intensifies the problem. The SuDS model is a ‘green-grey’ infrastructure intervention that reduces the impacts of floods in urban areas.

Process of Implementation:

The project followed the following steps: (1) approach selection, (2) urban planning review, (3) site survey, (4) project location agreement with local government, (5) economic technical report, (6) construction, (7) operational manual, (8) upscaling
