<p>The transport of contaminants has been a problematic issue for many years, mainly due to the adverse impact of the contaminants on the quality of groundwater. In order to analyse this, this study has developed a prediction model that allows the early detection ...

The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. Therefore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid ...

This paper provides theoretical background, laboratory data and full-scale measurements useful in understanding the interaction between soils and geosynthetics under unsaturated conditions. It also includes an evaluation of the current state of knowledge regarding ...

The objective of this paper is to examine the influence of correlation length and hydraulic conductivity distribution on the probability of failure of a clay liner system. To achieve this objective, a two-dimensional (in plan) clayey liner system is simulated ...

<p>Nine issues of importance to the use of geomembranes (GMs) and geosynthetic clay liners (GCLs) as part of composite liners in geoenvironmental applications are examined. These issues include the effect of: GCL-leachate compatibility on hydraulic conductivity; ...

<p>An alternative procedure to determine the hydraulic conductivity function (k-function) based on relationships between saturated hydraulic conductivity and void ratio and between air-entry value and void ratio is proposed. The procedure was applied to determine ...

<p>Packer test data and tunnel inflow observations are used to show that the distribution of equivalent hydraulic conductivity obtained for a rock mass from borehole packer testing will be biased if the orientations of the planned tunnel and testing borehole ...

A literature survey was conducted and fracture influences on engineering behavior of glacial till are summarized, specifically with regard to saturated hydraulic conductivity, consolidation potential, and shear strength

This paper presents the experience of a specialty contractor from a number of projects, where an incompatibility was discovered and alternate materials were used to find successful solution for slurry cutoff wall ground water blocking. Monitoring results from ...

<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. ...
