Modelling of groundwater-vegetation interactions in a tidal marsh

Wetting and drying due to tidal fluctuations affect soil conditions and hence plant growth in tidal marshes. Here, a coupled one-dimensional model was developed to simulate interacting groundwater flow and plant growth in these wetlands. The simulation res ...

Moisture and energy dynamics in fields soils

Francesco Ciocca

Soil moisture is crucial to water-cycle as it affects infiltration, runoff and land-atmosphere interactions. In dry soils the role of water vapor fluxes becomes essential and causes a tight coupling between soil moisture dynamics and heat transfer, which m ...

The origin of the pozzolanic activity of calcined clay minerals: A comparison between kaolinite, illite and montmorillonite

Karen Scrivener, Rodrigo Fernandez Lopez

This paper investigates the decomposition of three clayey structures (kaolinite, illite and montmorillonite) when thermally treated at 600 degrees C and 800 degrees C and the effect of this treatment on their pozzolanic activity in cementitious materials. ...

Axisymetrical infiltration in soil imaged by non-invasive electrical resistivimetry

Jordi Batlle-Aguilar

To progress in the monitoring and understanding of soil water processes, geophysical methods can be helpful because they are non invasive and as such do not disturb either the structure or the water dynamics of the soil. In this study we attempt to image w ...

Calcined clayey soils as a potential replacement for cement in developing countries

Rodrigo Fernandez Lopez

Concrete is the building material with the greatest potential for meeting the increasing housing demand in developing countries. Locally available materials should be considered as cement replacement in order to lower the costs and the environmental impact ...

Effect of mineral reactions on the hydraulic properties of unsaturated soils: Model development and application

David Andrew Barry, Laurin Wissmeier

The selective radius shift model was used to relate changes in mineral volume due to precipitation/dissolution reactions to changes in hydraulic properties affecting flow in porous media. The model accounts for (i) precipitation/dissolution taking place on ...

Fonctionnement hydrique de différents types de placages sableux dans le sahel burkinabè

Dial Niang

The study was performed in the Sahelian part of Burkina Faso. The country is subject to difficult climatic conditions, a strong demographic growth and a continuous decrease in soil fertility. The resulting degradation affects the processes which govern eco ...

Axysimetrical water infiltration in soil imaged by non-invasive electrical resistivimetry

Jordi Batlle-Aguilar

Axisymetrical infiltration of water in soil has been largely studied since the development of tension disc infiltrometers. Procedures have been developed to derive the hydraulic properties of soils from axisymetrical infiltration measurements but rely on s ...

Aggregate bed Deformation and Hydraulic Conductivity

Dani Or

The frequent use of earth materials for hydraulic capping and waste containment requires improved understanding of relationships between soil mechanical dynamics and its hydraulic and transport properties. We study deformation of pores embedded in viscopla ...
