A combination of the Hashin-Shtrikman bounds aimed at modelling electrical conductivity and permittivity of variably saturated porous media

Alessandro Brovelli

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 ...

Buffering soil-water acidity in chlorinated solvent bioremediation schemes

Christof Holliger, David Andrew Barry, Alessandro Brovelli, Clare Robinson, Elsa Marina Lacroix

Chlorinated solvents form a significant part of groundwater contamination worldwide. They are difficult to remove via physical means, and anaerobic source-zone remediation based on provision of fermentable e-donor is an attractive clean-up dechlorination o ...

Effect of raindrop splash and transversal width on soil erosion: Laboratory flume experiments and analysis with the Hairsine-Rose model

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The parameter consistency of the one-dimensional Hairsine-Rose (H-R) erosion model under conditions of significant rainfall splash was examined. To account for the splash characteristic length scale and its interaction with the transverse erosion width, ex ...

Recent developments in numerical modelling of subsurface flow constructed wetlands

Alessandro Brovelli

Numerical modelling of subsurface flow constructed wetlands (CWs) gained increasing interest during the last years. The main objective of the modelling work is, on the one hand, to increase the insight in dynamics and functioning of the complex CW system b ...

Bioclogging in porous media: Model development and sensitivity to initial conditions

Flavio Malaguerra, David Andrew Barry, Alessandro Brovelli

This work presents a numerical model able to simulate the effect of biomass growth on the hydraulic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled flow and reactive-transport code -- PHWAT -- was implemented. ...

Tidal influence on BTEX biodegradation in sandy coastal aquifers

David Andrew Barry, Alessandro Brovelli, Clare Robinson

A numerical study was conducted to investigate the influence of tides on the fate of terrestrially-derived BTEX discharging through an unconfined aquifer to coastal waters. Previous studies have revealed that tide-induced seawater circulations create an ac ...

Effective permittivity of porous media: a critical analysis of the complex refractive index model

Alessandro Brovelli

The availability of reliable constitutive models linking he bulk electric properties of porous media to their inner structure is a key requirement for useful quantitative applications of noninvasive methods. This study focuses on the use of dielectric meas ...

Numerical modeling of tidal influence on density-dependent contaminant transport

David Andrew Barry, Alessandro Brovelli

Transport of contaminants in coastal aquifers subject to tidal fluctuation is an important topic in hydrogeology as a consequence of the significant development of human activities near the shoreline. Despite this, relatively little work has been done to i ...
