Air Entrainment in Skimming Flow on Stepped Spillways: the Effect of an Abrupt Slope Change

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Mohammad Javad Ostad Mirza

Numerous stepped spillways were built during the last decades. In particular, a stepped spillway may be integrated economically into the downstream face of a RCC gravity dam, or on valley flanks besides embankment or rockfill dams, where slope changes may ...

Steep-slope Metal-Insulator-Transition VO2 Switches with Temperature-Stable High ION

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Michele Tamagnone, Wolfgang Amadeus Vitale, Antonio Paone

This work reports a detailed experimental investigation of the slope of the current switching between OFF and ON states exploiting the metal-insulator-transition in vanadium dioxide devices. The reported devices are CMOS compatible 2-terminal switches. We ...

Air entrainment and pressure development in skimming flow on an abrupt slope change on stepped spillways

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Mohammad Javad Ostad Mirza

Numerous stepped spillways were built to date, namely on RCC gravity dams or on valley flanks besides embankment or rockfill dams, while some others are currently under design or construction. In some cases, slope changes may be required on stepped chutes, ...

Entraining avalanches on slopes: results from experiments using PIV on viscoplastic gravity currents.

Christophe Ancey, Belinda Margaret Bates

In order to conduct experiments simulating entrainment by avalanches on slopes, it was necessary to select a material which could act as both a stationary entrainable layer, mimicking undisturbed mud or snow, and a flowing mass, representing the flowing av ...

Analytical approximation for the recession of a sloping aquifer

David Andrew Barry, Marc Parlange

An approximation is obtained for the recession of a sloping aquifer. The analytical approximation can provide a useful tool to analyze data and obtain physical properties of the aquifer. In contrast to the case of a horizontal aquifer, when plotting the ti ...

Digital holographic moiré for the direct and simultaneous estimation of strain and slope fields

Pramod Rastogi, Rishikesh Dilip Kulkarni

A novel method is proposed for the direct and simultaneous estimation of multiple phase derivatives corresponding to strain and slope fields from a single moiré fringe pattern in digital holographic moiré. The interference field in a given row/column is a ...

Hydraulics, Air Entrainment, and Energy Dissipation on a Gabion Stepped Weir

Davide Wüthrich

In the last decades the design of stepped spillways regained some interest because of their suitability with new construction methods including gabions. The hydraulic performances of gabion stepped weirs were investigated experimentally in terms of the flo ...

Abutment stability assessment of the Hongrin arch dam using 3D distinct element method

Azad Koliji, Jian Zhao, Thierry Bussard

The Hongrin north dam is a double curvature concrete arch dam located in western Swiss Prealps, which attains 125m high. The right bank abutment of the dam mainly consists of intensively jointed Neocomian limestone and exhibits zones of potential instabili ...

Modeling the Onset of Shallow Landslides in Partially Saturated Slopes Subjected to Rain Infiltration

Lyesse Laloui, Mathieu Nuth, John Eichenberger

Heavy rainfall can lead to shallow slips on slopes which are often initially in a state of partial water saturation. A multiphysics approach and advanced constitutive modeling are necessary to take into account the physical key processes in partially satur ...
