Application of methods for evaluating aquifer-system parameters: case of soil in My Thuan bridge, Vinh Long province

Abstract

Determining hydrogeological parameters is one of the important tasks of groundwater dynamics, in which the storage coefficient is anindispensable parameter to predict subsidence. Compaction and water-level data were assumed to collect data from a boreholeextensometer recorded and groundwater pumping test in My Thuan bridge, Vinh Long province to estimate elastic and inelasticspecific coefficient (S) in aquifer-system. The purpose of this study is to estimated and compared specific storage by three methodssuch as Theis’s method, Riley’s method and Galloway’s study in My Thuan bridge site, Vinh Long province. The final value of thestorage coefficient is 0.00052. The results of this study also are the basis for calculating settlement and the impact that mining mayhave on regional groundwater flow systems.
