Construction of Urban Water Secure Landscape Under Extreme Rainfall Conditions
With the acceleration of urbanization,an increasing number of people in China are gathering in cities,and the built-up area of cities is expanding.Correspondingly,from the perspective of urban hydrology,the area and proportion of water-proof underlying earth surface are also increasing.When a rainfall event occurs in a city,due to the existence of a large number of hardened underlying earth surfaces in the city,the rainwater that cannot seep down in the short term will form runoff,and the risk of flooding in the city will continuously increase.In fact,in Europe and other countries and regions,there have been practical studies on extreme rainfall landscape at the site scale,and these design concepts will have a great guiding and inspiring effect on China's water secure landscape design under extreme rainfall.
