Benchmark of experimental techniques for measuring and controlling suction

The paper presents a benchmarking study carried out within the ‘Mechanics of Unsaturated Soils for Engineering’ (MUSE) network aimed at comparing different techniques for measurement and control of suction. Techniques tested by the eight ‘Mechanics of Unsa ...

Modern comprehensive approach to monitor the morphodynamic evolution of a restored river corridor

Paolo Perona

River restoration has become a common measure to repair anthropogenically-induced alteration of fluvial ecosystems. The inherent complexity of ecohydrologic systems leads to limitations in understanding the response of such systems to restoration over time ...

Tide-induced surface water and groundwater interactions in coastal wetlands

David Andrew Barry

Intertidal wetlands such as salt marshes are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on 3D, variably ...

Modelling and analysis of hydropeaking in alpine catchments equipped with complex hydropower schemes

Anton Schleiss, Martin Peter Bieri

High-head storage hydropower schemes in Alpine areas are required to produce peak energy and to regulate electricity grids. Nevertheless the unsteady turbine operations induce hydropeaking in the river downstream of the powerhouse. The developed hydrologic ...

An advanced calibration process for a thermo-hydro-mechanical triaxial system

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper presents an innovative double cell triaxial system developed for better understanding of the complex thermo-hydro-mechanical behaviour of soils. In addition to the conventional triaxial mechanical testing, the equipment is aimed to perform sucti ...

Modelling of biogeochemical transformations in riparian soils: lessons learned from the Thur river revitalization experiment and open questions

David Andrew Barry, Alessandro Brovelli

In recent years, the key environmental importance of natural, healthy riparian ecosystems and soils has been recognized and restoration of degraded lands towards their former natural state has become an area of active research worldwide. Land use changes a ...

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 ...

Influence of the moisture content on the shear strength of welded wood-to-wood connections

Yves Weinand, Bernhard Stamm, Benjamin Hahn, Georg Lorenz Rossmair

Friction welding of wood is an innovative process, able to join pieces of wood without additional adhesives. Because of its hygroscopic properties, the wood matrix absorbs humidity at the surface from the surrounding atmosphere. Its moisture content is str ...

Specification and site control of the permeability of the cover concrete: the Swiss approach

Emmanuel Denarié

It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (covercrete) determine the service life of the structure. S ...

Leaching and transformability of transgenic DNA in unsaturated soil columns

Unsaturated soil columns were used to examine the transport of the plasmid pLEPO1 and plant DNA (transplastomic tobacco DNA), both carrying an antibiotic resistance gene (aadA gene), and the capacity of bacteria to incorporate the gene in their genome afte ...
