Study on combining flood control with rainwater utilization of airports in China

Abstract

For an airport, on one hand it is necessary to make flood control and drainage in rainy seasons; on the other hand, it is also often faced with the shortage of water resource problem. Therefore it is very important to study on combining flood control with utilization of rainwater resource for airports. This paper makes analysis and study on the present situation of flood control and rainwater utilization of airports, and then proposes to combine engineering measures with non-engineering measures for the airport flood control and rainwater utilization. The applications of Changbei Airport and Qingyang Airport are analysed, both of them locate in the south of China. Based on establishing relevant policies and increasing investment, some feasible methods are adopted, such as building storage tanks for collecting rainwater. That not only can control the flood and drainage effectively, but also provide water for the airport grassland and landscape and achieve beautification of the airport surrounding landscape. Application of these measures provides practical solutions to flood controlling and rainwater collecting problems of airports, therefore has certain reference significance to other airports for flood control and rainwater utilization.
