Samplinghelper a web-based tool to assess the reliability of sampling strategies in sewers and receiving waters

David Andrew Barry, Luca Rossi, Nathalie Chèvre Rossi

Sampling is a key step in the analysis of chemical compounds. It is particularly important in the environmental field, for example for wastewater effluents, wet-weather discharges or streams in which the flows and concentrations vary greatly over time. In ...

Experimental parametric study for hydraulic design of PKWs

Anton Schleiss, Marcelo Leite Ribeiro

The implementation of a new type of labyrinth spillway, called PKW (Piano Key Weir) reveals as a performing alternative for increasing the overflow capacity of existing dams. The optimal hydraulic design of such structure is however not obvious due to the ...

Investigation of micropollutants in two laboratory-scale constructed wetlands: experimental data and modeling

Pierre Claude Jean Queloz

In recent years, new types of water contaminants have emerged. More and more focus is notably set on pharmaceuticals, personal care products or pesticides, as it has been observed that these substances are commonly found in surface water. This contaminatio ...

Probabilistic risk assessment of urban stormwater discharge

David Andrew Barry, Luca Rossi, Nathalie Chèvre Rossi

Urban stormwater is an important source of detrimental impacts for receiving waters. Discharges from separated or combined sewer systems are recognized as a major contamination input to the environment. Moreover, these discharges may impact the morphologic ...

Probabilistic environmental risk assessment of urban wet-weather discharges: an approach developed for Switzerland

Luca Rossi, Nathalie Chèvre Rossi

Technical solutions aimed at limiting the impacts of urban wet-weather discharges are historically based on an end-of-pipe approach. The characteristics of wet-weather discharges, e. g. intermittent pollution loads, high variations in pollutant concentrati ...
