Research Of Filed Scale Experiment And Water Environment Management Scheme On River Network In Plain Area

Based on the planning of water environmental protection in plain river network areas, this paper mainly studies on the calculation methods of water environmental capacity and projects of water quality improvement.This paper takes Changshu City as an example. Near by the Changjiang River,this aera has good condition of transferring water.Based on field scale transferring water experiment ,this paper establishes hydraulics and water quality numerical modeds of Changshu area .Using the models, this dissertation focuses on the deep research of the two projects of water quality improvement and also a quantitative analysis of the way of obstructing contamination.Then this paper studies water environmental capacity of the aera and the methods to increase invironmental capacity.This research provide reasons for optimizing projects of transferring water in river network areas and steps of obstructing contamination.
