Abstract: Abstract The low impact development (LID) concept aims to control storm runoff and pollution through decentralized, small-scale source control to bring the development area as close to the natural hydrological cycle as possible. A large number of hardened pavement construction, so that the airport impervious area accounted for a high proportion, affecting the natural hydrological cycle. The low impact development of the sponge airport is favored by the Civil Aviation Administration of China and airports. Compared with the traditional airport drainage method, the drainage effect after the application of LID facilities needs to be further studied. In order to compare the effects of drainage schemes such as natural drainage, pumping station drainage and the combination of low impact development and pumping stations, three kinds of airport drainage schemes are designed. Then taking an airport along the southeast coast of China as an example, the simulation models of different drainage schemes are constructed and analyzed under the actual rainfall on May 11,2014. The results show that the drainage scheme combined with LID and pumping stations has the best effect on runoff. The application of rain barrels and permeable paving has greatly reduced the total inflow of Reservoir 2 in Catchment B, from 27.5 m3/s to 19.6 m3/s, with a reduction rate of 28.8%. For the multi-peak rainfall process, the reduction effect of rainfall peak flows decreases with the soil saturated gradually, and the reduction effect of the first peak and the second peak is better than that of the third peak. The study analyzes the drainage effect of different drainage schemes, and the number and the best opening scheme of pumping station for reservoirs are finally obtained. The results provide the theoretical basis for the design and operation management of the drainage scheme of sponge airports.
