Combined estimation of effective electrical conductivity and permittivity for soil monitoring

The mapping of moisture content, composition and texture of soils is attracting a growing interest, in particular with the goal of evaluating threats to soil quality, such as soil salinization. Fast non-invasive geophysical surveys are often used in this c ...

Constitutive models for the joint estimation of electrical conductivity and permittivity of variably-saturated soils

Alessandro Brovelli

In the context of sustainable development, there is a growing interest in mapping soil characteristics and land use, in particular to evaluate threats to soil quality. Fast non-invasive geophysical surveys have been used to estimate the areal distribution ...

Effect of stone cover on rainfall-driven soil erosion with negligible surface roughness

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Numerous studies have shown that, for soils with sparse vegetation cover, stones/rock fragments are an important factor controlling the hydrological response and soil erosion yields. Additionally, it has been observed that this effect is complex and ambiva ...

Stochastic modeling of soil salinity

Andrea Rinaldo, Samir Suweis, Amos Maritan

A minimalist stochastic model of primary soil salinity is proposed, in which the rate of soil salinization is determined by the balance between dry and wet salt deposition and the intermittent leaching events caused by rainfall events. The long term probab ...

The diffuse infiltration of road runoff: an environmental improvement

Aurèle Parriaux, Michaël Bensimon, Pascal Piguet

The Laboratory of Engineering and Environmental Geology (GEOLEP) has been mandated by Swiss authorities (Swiss Federal Road Office FedRO) to test a new road runoff management concept. This concept promotes the diffuse infiltration of road runoff into infil ...

Basin-scale soil moisture dynamics and the probabilistic characterization of carrier hydrologic flows: Slow, leaching-prone components of the hydrologic response

Andrea Rinaldo, Gianluca Botter

This paper aims at a first theoretical step toward the probabilistic modeling of nutrient contents in catchment-scale soil states. To this end, we wish to characterize probabilistically the slow, leaching-prone component of the hydrologic response, which c ...

Modeling the role of partitioning substrates in DNAPL column studies

David Andrew Barry

SABRE (Source Area BioREmediation) is a public/private consortium of twelve companies, two government agencies, and three research institutions whose charter is to determine if enhanced anaerobic bioremediation can result in effective and quantifiable trea ...

Conjugation of atrazine in vetiver (Chrysopogon zizanioides Nash) grown in hydroponics

Jean-Paul Schwitzguebel, Sylvie Vullioud-Marcacci

The resistance mechanism of vetiver (Chrysopogon zizanioides Nash) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazine rely on hydroxylation mediate ...

Modelling solute transport in structured soils: Performance evaluation of ADR and TRM models

David Andrew Barry

The movement of chemicals through the soil to the groundwater or discharged to surface waters represents a degradation of these resources. In many cases, serious human and stock health implications are associated with this form of pollution. The chemicals ...

Etude des processus hydrologiques par l'application du traçage environnemental

Abstract The main objective of this research is to improve the comprehension of the hydrological behaviour of natural catchments. This study is based essentially on the observation and the measurement of hydrological processes on the Haute-Mentue experimen ...
