District scale influence of waste heat on the subsurface conditions: a numerical investigation for Chicago

Stéphane Hartmann

Since the 20th century, the rate of urbanization in the world has been increasing exponentially and will reach 68% in 2050. In parallel with this expansion, the size and activities of cities are also greatly growing. As a result, cities are depleting avail ...

Examination of the seepage face boundary condition in subsurface and coupled surface/subsurface hydrological models

Damiano Pasetto

A seepage face is a nonlinear dynamic boundary that strongly affects pressure head distributions, water table fluctuations, and flow patterns. Its handling in hydrological models, especially under complex conditions such as heterogeneity and coupled surfac ...

Streamwater pCO2in an Alpine Headwater Catchment

Tom Ian Battin, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

Boreal and alpine streams are highly sensitive to climate change. Previous studies have shown the relevance of streams for carbon cycling in boreal landscapes. Less work has been done on alpine streams, and we do not understand the contributions from these ...

Shear velocity estimates in rough-bed open-channel flow

Ulrich Lemmin, Fereshteh Bagherimiyab Hunkeler

Shear velocity u(*) is an important parameter in geophysical flows, in particular with respect to sediment transport dynamics. In this study, we investigate the feasibility of applying five standard methods [the logarithmic mean velocity profile, the Reyno ...

Effect of Groundwater on Landslide Triggering

Cornelia Sara Brönnimann

Landslides belong to the most important natural hazards in all mountainous regions. It is wellknown that water is one of the major triggers of landslides. Numerous landslide studies discuss different effects that water may have on slope stability: decreasi ...

Using geotypes for landslide hazard assessment and mapping: a coupled field and GIS-based method

Aurèle Parriaux, Séverine Bilgot

Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduces in 1997 a method to realize landslide hazard maps. It is routinely u ...

Geological heterogeneity in landslides

Boris Matti

Significant progress has been made these last decades in the development of hydrogeological numerical flow modelling for describing the hydrodynamic behaviour of landslides. However, these new sophisticated methods are still very seldom used in the problem ...

Application de la méthode des géotypes à la cartographie des secteurs de protection des eaux souterraines ainsi qu'à la détermination de la susceptibilité aux instabilités de versants

Séverine Bilgot

The aim of this study is to develop new methods for landslides mapping and water resources protection and management using geotypes and GIS. The first part of this report deals with the conception and the use of a new methodology for groundwaters’ protecti ...
