Impulse waves generated by snow avalanches falling into lakes

In recent years, the number of water reservoirs in high-altitude areas has increased. They are often used to provide water for various activities related with recreational (i.e. skiing) and production activities. Many of such reservoirs are threatened by s ...

Stochastic Modelling of Reservoir Sedimentation in a Semi-Arid Watershed

Nicolas Jean François Pascal Ghislain Adam, Michel Pirotton

Sedimentation in large reservoirs is a major concern in semi-arid regions characterized by severe seasonal water scarcity. As a contribution to improved sediment management, this study analyses the real case of the reservoir of Sidi Yacoub in the north of ...

Experimental generation of tsunami-like waves

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

In the context of a comprehensive research project investigating the hydrodynamic loading on structures with openings, this paper focuses on the wave generation techniques currently used and the test results associated with it, proposing a particular tsuna ...

River Flow 2014 - International Conference on Fluvial Hydraulics

Despite the mechanisms of reservoir sedimentation being well known for a long time, sustainable and preventive measures are rarely taken into consideration in the design of new reservoirs. To avoid operational problems of powerhouses, sedimentation is ofte ...

Hydraulische Bemessung des Klaviertastenwehrs

Anton Schleiss, Michael Pfister

The Piano Key Weir (PKW) is a hydraulically attractive alternative to linear overflow weirs, increasing the unit discharge for similar heads and spillway widths. This advantage allows for operating dam reservoirs on an increased level and thereby provides ...

Impacts by dams: From water quality modelling to management optimization

Alfred Johny Wüest

Dams are prone to causing negative effects on downstream ecosystems by their potential to alter riverine water quality. In the case of Itezhi-Tezhi Reservoir (Zambia), a nutrient-poor wetland located downstream is affected by low oxygen concentrations owin ...

Continuous Long-Term Observation of Suspended Sediment Transport between Two Pumped-Storage Reservoirs

Anton Schleiss, Giovanni De Cesare, Michael Müller

Transport of suspended sediment between the two reservoirs of a pumped-storage plant in Switzerland was monitored over an 8-month period. A turbidity probe was installed on the upstream end of the pressure shaft, in which real-time monitoring was ensured b ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Integrated flood forecasting and management system in a complex catchment area in the Alps—implementation of the MINERVE project in the Canton of Valais

Javier García Hernández, Bastien Roquier

A complex hydrologic-hydraulic model has been developed for the Upper Rhone River basin in Switzerland. It is currently operational in the Canton of Valais for real-time flood forecasting and management, providing automatic warnings to the crisis cell of t ...
