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 ...

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

Giovanni De Cesare, Anton Schleiss, 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 ...

Pattern-oriented memory interpolation of sparse historical rainfall records

Anton Schleiss, Théodora Cohen Liechti, José Pedro Gamito de Saldanha Calado Matos

The pattern-oriented memory (POM) is a novel historical rainfall interpolation method that explicitly takes into account the time dimension in order to interpolate areal rainfall maps. The method is based on the idea that rainfall patterns exist and can be ...

Bulk velocity measurements by video analysis of dye tracer in a macro-rough channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Steep mountain rivers have hydraulic and morphodynamic characteristics that hinder velocity measurements. The high spatial variability of hydraulic parameters, such as water depth (WD), river width and flow velocity, makes the choice of a representative cr ...

Pressure tunnels in non-uniform in situ stress conditions

Anton Schleiss

The bearing capacity of prestressed concrete-lined pressure tunnels is governed by the in situ stress of rock mass, which generally has different magnitudes in the vertical and horizontal direction. Two cases were distinguished, based on whether the vertic ...

Vortex interaction in patches of randomly placed emergent cylinders

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Ana Margarida Da Costa Ricardo

The flow field of multiple-cylinder configurations exhibits complex interactions between shear layers, vortexes and wakes. For high stem-Reynolds numbers, the flow is turbulent and, low and intermediate areal number-densities of cylinders, and turbulence i ...

Mitigation measures for fish habitat improvement in Alpine rivers affected by hydropower operations

Anton Schleiss, Armin Julius Peter, Émilie Person, Martin Peter Bieri

In mountainous areas, high-head-storage hydropower plants produce peak load energy. The resulting unsteady water release to rivers, called hydropeaking, alters the natural flow regime. Mitigating the adverse impacts of hydropeaking on aquatic ecosystems ha ...

Surge Wave Propagation in a Common Tailrace Channel for Two Large Pumped-Storage Plants

Giovanni De Cesare, Anton Schleiss, Martin Peter Bieri, Stéphane Christian Olivier Terrier

Sudden starting and stopping of turbines and pumps lead to highly unsteady flow in tailrace channels of hydropower plants (HPP). Submergence of Pelton turbines and air entrainment in pumps due to surge waves must be avoided by technical measures. The exist ...

Influencing Flow Patterns and Bed Morphology in Open Channels and Rivers by Means of an Air-Bubble Screen

Koen Blanckaert, Anton Schleiss, Violaine Dugué

The ability of a bubble screen to redistribute the flow field and bed morphology in shallow rivers and open channels has been investigated in laboratory experiments. Rising air bubbles generated by a pressurized porous tube situated on the bed induced seco ...

Bed load fluctuations in a steep channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Bedload transport rate fluctuations have been observed over time in steep rivers and flumes with wide grain size distributions even under constant sediment feeding and water discharge. The observed bedload transport rate pulses are periodic and a consequen ...

Flow restoration in Alpine streams affected by hydropower operations—a case study for a compensation basin

Anton Schleiss, Michael Müller, Martin Peter Bieri

Hydropeaking, resulting from rapid starting and shut-down of turbines, is one of the major hydrological alterations in Alpine streams. The upper Aare River basin in Switzerland comprises a complex high-head storage hydropower scheme. The significant turbin ...

Three-dimensional numerical modeling of flow field in rectangular shallow reservoirs

Anton Schleiss

Flow field in shallow waters, which is characterized by its complex mixing process and inherent dynamic nature, is interesting mainly due to its practical importance (e. g. in free flushing operation and sedimentation in large reservoirs). 3D numerical mod ...

Effects of rock mass anisotropy on deformations and stresses around tunnels during excavation

Anton Schleiss

rock mass where the in situ state of stress is uniform. The rock mass was assumed to behave elastically and two cases were examined: whether the rock mass has an isotropic elastic property or not. A two-dimensional plain strain elastic-plastic Jointed Rock ...

Stress–strain analysis of a toric pipe for inner pressure loads

Anton Schleiss, David Ferràs Segura

This research aims to enhance the knowledge on stress–strain states of a coiled pipe used for Hydraulic transient experiments. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an in ...

Effet de la rugosité du fond d’un réservoir rectangulaire à faible profondeur sur le champ d’écoulement

Anton Schleiss

La sédimentation de la charge en suspension dans les réservoirs est un phénomène assez complexe à gérer. Des solutions existent pour maitriser ou réduire l’alluvionnement mais elles ne sont généralement pas faciles à expliquer, surtout dans les retenues tr ...

Morphodynamic changes in a natural river confluence due to a hydropower modified flow regime

Anton Schleiss, Marcelo Leite Ribeiro, Simon Wampfler

River channel confluences form important morphological components of any river system. This article presents the results of an investigation on a natural river confluence in Switzerland. The aim of the field work performed at the confluence of the Sarine ( ...
