Flood impact analysis of wetland project in flood storage and detention area based on Mike 21 model
The wetland project will divert part of the river water to the constructed wetland for purification,which can effectively improve the water quality of the Daqing River and keep the water quality of the Taitou cross-section stably at Class Ⅳ.Taking the wetland project in the flood storage and detention area as an example,this paper uses Mike 21 software to establish a model to simulate the impact of flood flow on the flood storage and detention area before and after the construction of the project,so as to provide reliable data for flood control and scheduling.
