The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...
In this paper we propose a novel theoretical model for the dielectric response of variably saturated porous media. A model is constructed for fully saturated porous media as a combination of the well established Hashin and Shtrikman [1962] bounds and Archi ...
This paper is an overview of known and new results about the coupling of Navier-Stokes and Darcy equations to model the filtration of incompressible fluids through porous media. We discuss coupling conditions and we analyze the global coupled model in orde ...
A software tool for the simulation of one-dimensional unsaturated flow and solute transport together with biogeochemical reactions in the vadose zone was developed by integrating a numerical solution of Richards' equation into the geochemical modelling fra ...
Numerous industries have been using chlorinated ethenes (CEs), mainly tetrachlorethene 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 ...
The behavior of As in the subsurface environment was examined along a transect of groundwater monitoring wells at a Superfund site, where enhanced reductive dechlorination (ERD) is being used for the remediation of groundwater contaminated with chlorinated ...
This paper investigates the morphologic impacts of the widening of tributaries in confluence zones by means of systematic hydraulic tests performed in a confluent laboratory flume. The confluent channels are connected with an angle of 90° and the main chan ...
Chlorinated ethenes (CEs) represent a major environmental concern in most industrialized countries. These compounds, used as solvents and degreasing agents since the 1940s, have been released accidentally into the environment. Being recalcitrant to aerobic ...
Motivated by mechanical analysis of bones and bone-implant systems, a 3D constitutive law describing the macroscopic mechanical behaviour of both cortical and trabecular bone in cyclic (not fatigue) overloads is developed. The proposed model which mathemat ...
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 ...
