While scientists are wracking their brains to find ways to improve the accuracy of flood forecasting under the changing climate, there are architects who have accepted the future uncertainty and begun to make their own projections.
“Flooding is inevitable in the future. It is time to think how to adapt to it,” said Liao Kuei-hsien, assistant professor in the School of Architecture of the Chinese University of Hong Kong, suggesting that the manmade surroundings be designed to be floodable and that more public space, especially in urban areas, be multi-functional so it can be opened during rainfall for storm-water storage.
Liao clarified the differences between flooding, a natural phenomenon, flood hazard, a potential threat of flooding to human beings, and flood disaster, which causes damage to residents and the economy.
As the current flood control systems are insufficient to sustain future flood disasters, it is important “to increase the resilience of the city and to prevent flood hazards from becoming flood disasters”, Liao said, explaining that resilience means a city in flood recovers quickly and continues to operate normally.
“We’ ll be living in an environment where flooding is natural. So we need to get used to it. Just let it flood,” she said, anticipating an environment which adapts to floods.
