On the other hand,when human activities vary groundwater states obviously,which include buried depth of groundwater table,mineralization degree of groundwater,moisture content and salt content of aeration zones,positive or negative eco - effect would yield.

on the basis of analyzing all-round the present situation and the existing problems of monitoring system for dynamic state of groundwater in Jilin Province,by the comparison and analysis among abroad and domestic monitoring systems for dynamic state of groundwater,the authors put forward planning scheme of monitoring system for dynamic state of groundwater in Jinlin Province in this paper .

Study Of The Mid-deep Groundwater Dynamics In Zhengzhou City

Based on analyses of groundwater level and water quality from 1963 to 2005,the groundwater dynamics of the water-filled aquifers in Feicheng colliery was studied.

Application of LM arithmetic in groundwater regime forecast;

Utilizing BP neural network to forecast groundwater regime;

This paper is to classify the groundwater regime according to projection function value through turning multi-dimensional data indexes into low-dimensional space by using projection pursuit cluster (PPC) model, and meanwhile optimizing its projection direction by immune evolutionary algorithm (IEA).
