Downstream relevance of reservoir management

The management of dams serves many purposes and goals all over the globe, and has important consequences for the downstream rivers and lakes. Among the more than 50,000 so-called large dams, the biggest are located in alpine regions. As a result, the water ...

Natural streamflow regime alterations: Damming of the Piave river basin (Italy)

Andrea Rinaldo, Gianluca Botter

A novel approach is proposed to estimate the natural streamflow regime of a river and to assess the extent of the alterations induced by dam operation related to anthropogenic (e. g., agricultural, hydropower) water uses in engineered river basins. The met ...

Pharmaceuticals and Personal Care Products (PPCPs) in Effluent Matrices: A Survey of Transformation and Removal during Wastewater Treatment and Implications for Wastewater Management

Tamar Kohn

Pharmaceuticals and personal care products (PPCPs) represent pollutants of emerging concern, originating in surface and drinking waters largely from their persistence in wastewater effluent. Accordingly, a wealth of recent investigations has examined PPCP ...

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 ...

Hydrologic and biogeochemical controls of river subsurface solutes under agriculturally enhanced ground water flow

Janet Gordon Hering

The relative influences of hydrologic processes and biogeochemistry on the transport and retention of minor solutes were compared in the riverbed of the lower Merced River (California, USA). The subsurface of this reach receives ground water discharge and ...

Modelling carbon and nitrogen turnover in variably saturated soils

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

Natural ecosystems provide services such as ameliorating the impacts of deleterious human activities on both surface and groundwater. For example, several studies have shown that a healthy riparian ecosystem can reduce the nutrient loading of agricultural ...

MNA as a remedy for arsenic mobilized by anthropogenic inputs of organic carbon

Janet Gordon Hering

The potential application of monitored natural attenuation (MNA) as a remedy for ground water contaminated with arsenic (As) is examined for a subset of contaminated sites, specifically those where naturally occurring As has been mobilized due to localized ...

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 ...

Depuration of highway runoff water into grass-covered embankments

Pascal Boivin

The management of polluted road runoff water is an important issue in environmental protection. A strategy could be to perform local depuration by infiltration into the soils of the embankment, but knowledge for designing such systems is lacking. This stud ...
