Located in reservoir area of Dahuaqiao Hydropower Station Lancang River, the Dahua ancient deposit landslide exhibits high possibility reactivation due to impoundment. In this study, physical model tests are conducted investigate variations groundwater, deformation, and failure process under different fluctuation speeds water level. Influence groundwater on stability when level fluctuating is a...

Abstract This study describes the results of groundwater table variation in Thanjavur District before and after monsoon seasons. Groundwater-level data acquired by field measurement elevation have been obtained from topographic survey. Groundwater is major source for different sectors this region, portion was used irrigation. The impacts geology, soil types, elevation, land-use changes were cri...

Karst aquifers have a high degree of heterogeneity and anisotropy in their geologic and hydrogeologic properties which makes predicting their behavior difficult. This paper evaluates the application of the Equivalent Porous Media (EPM) approach to simulate groundwater hydraulics and contaminant transport in karst aquifers using an example from the North Coast limestone aquifer system in Puerto ...

This paper presents an efficient method to analyze the aquifer response to periodic forcing. A complex transformation is used to change the time-dependent linear aquifer model into an equivalent time-independent problem of a complex function (referred to as the ‘‘complex amplitude’’ hereafter). The magnitude of the complex amplitude represents the amplitude of the sinusoidal fluctuation of the ...
