How do subordinate and dominant species in semi-natural mountain grasslands relate to productivity and land-use change?

Alexandre Buttler, Pierre Rémi Mariotte, Thomas Spiegelberger

Changes in agricultural practices of semi-natural mountain grasslands are expected to modify plant community structure and shift dominance patterns. Using vegetation surveys of 11 sites in semi-natural grasslands of the Swiss Jura and Swiss and French Alps ...

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 ...

Analysis of acidity production during enhanced reductive dechlorination using a simplified reactive transport model

David Andrew Barry, Alessandro Brovelli, Clare Robinson

Build-up of fermentation products and hydrochloric acid at a contaminated site undergoing enhanced reductive dechlorination can result in groundwater acidification. Sub-optimal pH conditions can inhibit microbial activity and lead to reduced dechlorination ...

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. ...

Ecohydrological Footprints

Samir Suweis

Ecohydrological footprints are defined as the response of ecosystem functions or services to changes in their hydrologic drivers. In this thesis, several diverse footprints are addressed: noise-driven effects on storage-discharge relations and catchment st ...

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 ...

Prescription-induced jump distributions in multiplicative Poisson processes

Andrea Rinaldo, Samir Suweis, Amos Maritan

Generalized Langevin equations (GLE) with multiplicative white Poisson noise pose the usual prescription dilemma leading to different evolution equations (master equations) for the probability distribution. Contrary to the case of multiplicative gaussian w ...

Predictive hydrogeochemical modelling of bauxite residue sand in field conditions

David Andrew Barry, Laurin Wissmeier

The suitability of residue sand (the coarse fraction remaining from Bayer´s process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth ...

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 ...

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 ...
