<p>Estimation of groundwater table by hydrogeologists in Ghana over the past decades has proven to be difficult due to the dearth of data on piezometric heads from the very few boreholes present to access this data. The importance of this information in infrastructure ...

The essential processes and mechanisms of the transport of contaminants from a river to a well field via a flood water retention area are presented.

<p>Autoregulation between groundwater flow and karst aquifer properties, duality of karst, nested model of geological discontinuities, scale effect on hydraulic parameters and use of numerical finite element models to check the interpretation of the global ...

This report provides an overview of some of the common approaches used to scientifically determine the important factors controlling the vulnerability of ground-water resources to contamination.

<p>Diavik Diamond Mines Inc. proposes to develop a diamond mining project at Lac de Gras in the Northwest Territories. As part of the Environmental Assessment, and mine design, estimates of mine water inflow quantity and quality were required. This paper describes ...

This brief overview of the hydrogeology and geohydrology of basin-fill aquifers in the northern Rio Grande Basin covers a large region that extends from the San Luis Valley of southcentral Colorado to the Hueco Bolson southeast of El Paso and Ciudad Juare ...

This paper presents the value of a good geotechnical model for underground works and how this can be achieved.

<p>Theoretically, three types of flow systems may occur in a small basin: local, intermediate, and regional. The local systems are separated by subvertical boundaries, and the systems of different order are separated by subhorizontal boundaries. The higher ...

Conceptual geological models of urban areas are an essential component of groundwater investigations as well as of urban groundwater management. For sustainable urban groundwater management there must be a coherent understanding of the local groundwater and ...

<p>In this study, a 2D finite-element analysis, using the SEEP/W program, was carried out to estimate the amount of groundwater flowing into a tunnel, as well as the groundwater tables around wetland areas during and after tunnel excavation through rock mass. ...
