Study on the groundwater vulnerability assessment in Tangshan plain area.
Zhang Si-cong · Acta Scientiae Circumstantiae · 2003
Depth to groundwater and other five parameters are selected to assess groundwater vulnerability in Tangshan plain area according to the specific conditions of this area. Numeric modelling is performed to obtain the rating system. Principal component analysis and factor analysis are used to get the weighting system. Based on the established assessment system and GIS technique, groundwater vulnerability assessment is conducted in this area and a groundwater vulnerability distribution map is developed which is a useful tool for groundwater protection. The assessment results are well consistent with the measured and predicted nitrate concentrations in this area.
