Success story #1: Sustainable urban drainage systems (SUDS)
Floods occur frequently in Viet Nam’s cities. In addition to seasonal flooding, random extreme flood events have disastrous economic and civilian impacts. The flood in the year 2000 alone took over 800 lives. Of all natural hazards present in Viet Nam, flooding is the most frequent, the most economically damaging and the deadliest. Sustainable urban drainage systems (SUDS) are systems designed to efficiently manage the drainage of surface water in the urban environment.
