Dynamic water allocation policies improve the global efficiency of storage systems

Water impoundment by dams strongly affects the river natural flow regime, its attributes and the related ecosystem biodiversity. Fostering the sustainability of water uses e.g., hydropower systems thus implies searching for innovative operational policies ...

Fine sediment routing in a cascade of alpine reservoirs: Influence of the inlet angle on settling of fine sediments

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

Reservoir sedimentation is, at present, one of the main concerns in the operational management of dams. The resulting reduction of storage capacity has negative impacts on the hydropower production, flood protection, and availability of water for irrigatio ...

BLOCKING PROBABILITY OF DRIFTWOOD AT OGEE CREST SPILLWAYS WITH PIERS: INFLUENCE OF WOODY DEBRIS CHARACTERISTICS

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Paloma Furlan

Spillways are designed to evacuate floods in a safe way. They should safely release water in order to avoid dam overtopping with its related damages. Nevertheless, it may be dangerous to assume that a flood is only carrying “clear” water. Large woody debri ...

Comprehensive power loss modelling to improve the performance of an Energy Recovery Station for water utility networks

François Avellan, Cécile Münch-Alligné, Loïc Andolfatto, Daniel Biner

The work presented in this paper details the methodology applied to inventory and estimate the power losses in a micro-turbine with counter-rotating runners. The separation between the impact of design parameters and operational parameters on each identifi ...

Chemical disinfectants

Tamar Kohn, Loïc Decrey

Safe water, sanitation, and hygiene provision and promotion are critical elements of emergency response to ensure human safety, health, and dignity. Disinfectants, such as chlorine, are widely used in emergency response to treat water for drinking. However ...

Fifteen years of microbiological investigation in Opalinus Clay at the Mont Terri rock laboratory (Switzerland)

Rizlan Bernier-Latmani, Alexandre Bagnoud

Microbiological studies related to the geological disposal of radioactive waste have been conducted at the Mont Terri rock laboratory in Opalinus Clay, a potential host rock for a deep geologic repository, since 2002. The metabolic potential of microorgani ...

First principle calibration of water vapor Raman lidars

Valentin Simeonov

A new method for calibration of water vapor Raman lidars based on first principles is proposed. The calibration constant of a Raman lidar is derived from a set of water vapor and nitrogen Raman backscatter signals measured with the lidar receiver in a cell ...

Influence of outlet discharge on the efficiency of turbidity current venting

Sabine Chamoun

Reservoirs created by dams are vital water infrastructures worldwide ensuring not only water, food and energy but also protecting against floods. Sedimentation endangers the sustainable use of these reservoirs. Fine sediments transported as suspension duri ...

Virus transfer at the skin-liquid interface

Tamar Kohn, Timothy R. Julian

Understanding virus transfer between liquid and skin is necessary to estimate transmission during water-related activities. In the present study, we modeled virus transfer from liquid-to-skin and skin-to-liquid. Specifically, we performed human subject stu ...

Open design of a fixed probe for water quality monitoring in rivers and lakes

Nils Pascal Bonfils

This bachelor project work aims to set up a prototype measurement station in the Sorge (a small river near the EPFL) to collect some data about the water and the environmental conditions. And also make the work reproducible so that someone, somewhere else ...
