Non-Stationary Hydrologic Transport in the Vadose Zone: Experimental Results of Multiple Tracer Injections in Lysimeters

Andrea Rinaldo, Pierre Claude Jean Queloz

Travel and residence times are well-known descriptors of hydrologic and solute transport in the vadose zone. It has been observed that their probability density functions are stationary only under specific conditions, rarely encountered in natural catchmen ...

Reclamation of low fertility soils using by-products and fast-growing trees

Marc Adami

The world population being increasing, a good energy production management is therefore necessary. Biomass production through short forest rotation by using fast-growing trees appears as a sensible way to limit fossil fuel uses. In Mediterranean regions of ...

The relationship between plant species richness and soil aggregate stability can depend on disturbance

Alexandre Buttler

Plant diversity has been shown to significantly increase topsoil aggregate stability of machine-graded ski slopes. We hypothesise that this effect is specific for these disturbed sites and that at sites of low and no disturbance the effect decreases. ...

Impact of flood deposits on earthworm communities in alder forests from a subalpine floodplain (Kandersteg, Switzerland)

Claire Guenat, Géraldine Michèle Bullinger, Jean-Michel Gobat, Renée-Claire Le Bayon

In many ecosystems, bioindication is a tool to estimate biodiversity and quality of environment. In soils,invertebrates are generally suitable bioindicators, especially earthworms. In floodplains, young alluvial soils are exposed to sedimentation and erosi ...

Soil mapping using electro-magnetic methods: development of a unified constitutive model.

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 ...

Hydrologic controls on equilibrium soil depths

Andrea Rinaldo, Ludovico Nicotina

This paper deals with modelling the mutual feedbacks between runoff production and geomorphological processes and attributes that lead to patterns of equilibrium soil depth. Our primary goal is an attempt to describe spatial patterns of soil depth resultin ...

An Innovative Device for Determining the Soil Water Retention Curve Under High Suction at Different Temperatures

Lyesse Laloui, Simon Salager, Marta Rizzi

In order to characterize the water retention behavior of fine soils, very high suction values have to be applied. In this range of values, the vapor equilibrium technique is usually used. This paper presents an innovative device, a sorption bench, which pe ...

Rainfall thresholds for shallow landslides based on a numerical analysis

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Shallow landslides in Alpine regions frequently occur during heavy precipitation events or extremely fast snow melting processes. Early-warning is mostly based on simple empirical rainfall intensity and duration curves indicating probable critical climatic ...

Carbon and nitrogen dynamics in a soil profile: Model development

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

In order to meet demands for crops, pasture and firewood, the rate of land use change from forested to agricultural uses has steadily increased over several decades, resulting in an increased release of nutrients towards groundwater and surface water bodie ...
