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 an
indispensable parameter to predict subsidence. Compaction and water-level data were assumed to collect data from a borehole
extensometer recorded and groundwater pumping test in My Thuan bridge, Vinh Long province to estimate elastic and inelastic
specific coefficient (S) in aquifer-system. The purpose of this study is to estimated and compared specific storage by three methods
such as Theis’s method, Riley’s method and Galloway’s study in My Thuan bridge site, Vinh Long province. The final value of the
storage coefficient is 0.00052. The results of this study also are the basis for calculating settlement and the impact that mining may
have on regional groundwater flow systems.
