Due to the complexity and effect of various uncertain factors of water diversion projects,the effect of water diversion measures on improvement of water environment has certain risk.

Elementary framework of economic benefit evaluation on water diversion projects

This paper makes a detailed discussion on the advantages and disadvantages of bioremediation and water division in trying to regain the quality of the polluted lake water.

Study on clean water diversion in Shanghai City;

The necessary and favorable conditions for clean water diversion are as follows: the tidal characteristic of the river network, the formation of regionalized comprehensive regulation pattern, the good water quality of water sources, and the research and practice of water diversion experiment.

As the water level in tidal area is changing fast, it is very important to choose a scientific gate operation scheme and a diversion and drainage scheme in the course of clean water diversion, and this will help to control scouring downstream the gate and to get better effect on the water quality improvement.

Based on statistical data,three different dynamic mathematical models were established and used to determine the environmental water demand under different sewage treatment rates and water diversion sources.
