Abstract

Abstract: In recent years, the excessive exploitation of groundwater resources caused a series of ecological and environmental problems, such as land subsidence, vegetation degradation, and soil salinization. The 3D groundwater aquifer model can intuitively show the spatial distribution of aquifer and provide decision and technical supports to water resource evaluation, prediction, and reasonable exploitation. By using GMS software, a 3D model of groundwater aquifers in some areas of Suzhou-Wuxi-Changzhou region is constructed based on the borehole data. The model is modified by partitioning the study area and by introducing virtual borehole and geological cross-section in the borehole sparse and stratigraphic pinch-out areas for enhancing the model precision. The results show that the accuracy has been significantly improved, and the 3D model revealed is basically consistent with the survey data. This model will be useful for guiding utilization of groundwater, optimization of planning structure, and development of water-saving irrigation measures.

Key words: groundwater, aquifer, 3D model, GMS software
