An analytical model is presented for the analysis of constant flux tests conducted in a phreatic aquifer having a partially penetrating well with a finite thickness skin. The solution is derived in the Laplace transform domain for the drawdown in the pumpi ...
Significant progress has been made these last decades in the development of hydrogeological numerical flow modelling for describing the hydrodynamic behaviour of landslides. However, these new sophisticated methods are still very seldom used in the problem ...
Most contaminated sites related to past industrial activities in Europe are adjacent to rivers and urbanized areas. These sites pose a major problem for water authorities and policy makers in terms of contaminants mobility, natural attenuation (or degradat ...
As geosynthetic clay liners (GCLs) are becoming integral components of modern municipal solid waste landfill lining systems, increased interest is directed at investigating their behaviour under different environmental stresses such temperature, chemical c ...

The continuous demand on new residential and economic areas of the modern society has to face up with problems posed by polluted sites related to former industrial activities, typically located in suburbs areas. These sites, known as brownfields, are often ...
Capillary pressures encountered in composite processing are often evaluated by measuring infiltration rates as a function of applied pressure. Such data are generally interpreted assuming slug-flow. Using the Brooks-Corey correlations we relax this assumpt ...
Changes in hydraulic properties of soils and aquifers as a result of biogeochemical transformations, such as bacteria growth and mineral phase precipitation/dissolution, may lead to significant modifications of the groundwater flow field. This affects in t ...
In unsaturated soil mechanics testing, total volume change of the specimen is related to both water and air volume changes and cannot be measured with the same techniques as in conventional saturated soil mechanics. Over the years, several methods have bee ...
Evaluation of aquifer yields with the conventional time- drawdown method is based on the assumption of Theisian or infinite radial flow (IRF) of ground water to a well. However, long-term aquifer yields are controlled by heterogeneities and boundary condit ...
Numerous industries have been using chloroethenes (CEs), mainly tetrachloroethene and trichloroethene, as non-flammable solvents since the beginning of the 20th century. Massive usage, along with careless handling and storage, made CEs one of the most abun ...
