Planning of Qingdao Jiaodong International Airport
The airport is located at the intersection of Bigou River, Nanjiaolai River and Dagu River, 11 kilometers northeast of jiaozhou city, Qingdao, with low terrain. In addition, the Dagu River section at the airport is a water source protection site and water storage reservoir in Qingdao, which is less than 10 kilometers away from the sea. A rubber dam for water storage is built downstream of it, and the normal water level of the river in rainy season is affected by many factors. According to the plan, a flood control dam is designed around the new airport in Qingdao. The designed terrain elevation of the airport side in the flood control dam is more than 6m, while the 100-year flood level of the river outside the flood control dam is more than 11m. To sum up, the design of airport drainage, flood control and drainage is extremely important because it involves airport safety.
