By combining Doppler radar VWP and the observing data of 300 meters resolution,we would be able to interpret the evolution of one convective torrential rain occurred in Qingdao in 26th August 20.

The classification of radar echo in the strong convection rainstorm weather into four types helps to utilize the characteristic of radar echo for forecast of the strong convection rainstorm weather.

Research on Simulation Model of Storm Runoff in Tianjin Urban District;

A simulation of storm runoff treatment with three types of subsurface flow wetlands(SFS) of the pilot-scale bed of blank plant,Phramites communis and Zizania caduciflora was studied.

In order to investigate the characteristics of urban storm runoff pollution of combined sewer system, monitoring sections were arranged in four catchment areas to make continuous monitoring on quality and quantity of storm runoff during heavy rain period.

Effect of impervious surface on stormwater runoff pollution in urban tourist attractions;

The pilot study on the treatment of rural stormwater runoff by the zeolite and zizania caduuciflora combined bed technology through simulating the character of rural stormwater runoff, is carried out.

Nitrogen, phosphorus and suspended solid in stormwater runoff are suggested as important parts of non- point source pollution and lake eutrophication.
