Application of two-dimensional stochastic model of water quality in simulating pollution zone;

Concentration distribution of oil droplets beneath a finitely-long oil slick at water surface and pollution zone;

The pollution zone distribution is simulated under a coupled pollutant superposition condition by using high precision mesh in a 21km river reach;and analysis is made to find whether the pollutant will have great influence on the water intakes in the reach,and so as to .

Study on phenolic contaminated zone of the Changjiang River in Wuhan;

Considering natural decrease, boundary limit and national standard of water quality,a calculation method for the range of the contaminated zone is presented in this paper.

Factors affecting the pollution belt at tidal estuaries;

The pollution belt of Yuehe River was calculated according to consider the irregularity of river and apply the cumulative flows coordinates method with two-dimensional water quality model.

The effects of channel diameter,perforation depth,damage zone depth,formation anisotropy and penetrating type were compared for penetrating through damage zone and not through.

The drilling damage zones and compacted zones of conventionally perforated wells have seriously harmful effects on the productivity.

Based on the present situation of water quality investigation and prediction of pollution sources, the 2-D steady-state water quality model was adopted for prediction of the length of polluted belts caused by pollutants discharged from various outlets into the river.

The diffusion characteristics and formation of polluted belt have to be considered for an accurate calculation of capacity of aquatic self purification in polluted river.
