Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...

Role of microbial cell properties on bacterial pathogen and coliphage removal in biochar-modified stormwater biofilters

Stormwater biofilters are distributed stormwater control measures for managing urban runoff. Recent work has shown that adding biochar to biofilters can reduce stormwater contaminant concentrations, including fecal indicator bacteria (FIB). However, the po ...

Hydromechanically coupled analysis of transient phenomena in a rainfall-induced landslide

Lyesse Laloui, Mathieu Nuth, John Eichenberger

Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall ev ...

Road runoff management using over-the-shoulder infiltration: real-scale experimentation

Aurèle Parriaux, Michaël Bensimon, Pascal Piguet

A new management policy regarding road runoff was proposed in 2002 by the Swiss Federal Office for the Environment (FOEN). This new concept is based on the diffuse infiltration of road runoff into embankment slopes, where soils will filter particles and co ...

Recyclage des eaux usées en irrigation : potentiel fertilisant, risques sanitaires et impacts sur la qualité des sols

Yeli Mariam Sou

The present study takes place in Ouagadougou (Burkina Faso), a typical Sub-Saharan city where water shortage and food crisis necessitate wastewater reuse in urban agriculture. Different issues linked to this practice were studied in two components separate ...

Vision-based system for the control and measurement of wastewater flow rate in sewer systems

David Andrew Barry, Luca Rossi, Daniel Sage, Laurent Son Nguyen, Salim Kayal

Combined sewer overflows and stormwater discharges represent an important source of contamination to the environment. However, the harsh environment inside sewers and particular hydraulic conditions during rain events reduce the reliability of traditional ...

The diffuse infiltration of road runoff: an environmental improvement

Aurèle Parriaux, Michaël Bensimon, Pascal Piguet

The Laboratory of Engineering and Environmental Geology (GEOLEP) has been mandated by Swiss authorities (Swiss Federal Road Office FedRO) to test a new road runoff management concept. This concept promotes the diffuse infiltration of road runoff into infil ...

Road runoff over the shoulder diffuse infiltration : real-scale experimentation and optimization

Pascal Piguet

A new concept of road runoff management, based on diffuse infiltration over the shoulder, was tested in a real-scale experimentation site located near Grandson, Switzerland. This new concept consists in diffusely infiltrating the road runoff in the infiltr ...
