Success story #3: Flood modelling & city drainage planning
Cities in Vietnam overly rely on traditional drainage systems to discharge surface-runoff. Often, when overflowing rivers concur with intense rainfall, this underground infrastructure does not have the capacity to drain the water in time. As a result, areas with high population density, critical infrastructure, such as hospitals and schools, and low-lying areas, where the poor and vulnerable often dwell, get flooded. In particular in the Mekong-Delta, urban flooding will increase due to climate change and other factors.
