Feasibility analysis of wetland restoration by using floodwater

摘要

The northeast of China spans monsoon precipitation zones. Asymmetrical precipitation distribution causes the heavy flood disaster and great demand of water supply. Flood control system of the Songhua River Basin (SRB) needs some flood detentions or retentions, and fortunately, the wetlands in SRB can be used to store floodwater and improve their ecological environment. Through a comprehensive analysis, the paper programs a research subject with two aspects: (1) using wetlands to regulate floods and mitigate flood damage, and (2) using floodwater to restore wetland ecological environment.
