Stepped Spillways: Technical Advance from 1900

Stepped spillways are currently a standard design in hydraulic engineering. Whereas these spillways were hardly employed until the advent to the Roller-Compacted Concrete (RCC) Technology in the 1980s, they were of particular interest from the 1990s for sp ...

Hydraulic design of A-type Piano Key Weirs

Anton Schleiss, Michael Pfister, Marcelo Leite Ribeiro

Piano Key Weirs (PKWs) are an alternative to linear overflow structures, increasing the unit discharge for similar heads and spillway widths. Thus, they allow to operate reservoirs with elevated supply levels, thereby providing additional storage volume. A ...

Preliminary Study on the Influence of an Air-Bubble Screen on Local Scour around a Bridge Pier

Anton Schleiss, Violaine Dugué, Sylvain Rigaud, Elham Izadinia

Flow interactions with a bridge pier and movable river bed result in local scour which can endanger bridge pier foundations. This scour is initiated by the downward flow and amplified by the so-called horseshoe vortex. A new method to reduce scouring aroun ...

Hydrodynamics of a Pump-Turbine Operating at Off-Design Conditions in Generating Mode

Vlad Hasmatuchi

Modern pump-turbines are subject to frequent switching between the pumping and generating modes with extended operation under off-design conditions. Depending on the specific speed of the pump-turbine, the discharge-speed as well as torque-speed generating ...

Characterization and modelling of low-pressure rf discharges at 2–500 MHz for miniature alkali vapour dielectric barrier discharge lamps

Nico de Rooij, Herbert Shea, Yves Pétremand, Vinu Lalgudi Venkatraman

Low-pressure dielectric barrier discharge (DBD) alkali vapour lamps are of particular interest for portable atomic clocks because they (1) could enable low-power operation, (2) generate the precise required wavelength, (3) are planar simplifying chip-level ...

Rainfall-discharge model of the Aubonne karst watershed (Swiss Jura)

Flavio Finger

The goal of this study was to develop a reservoir model for the Aubonne karst watershed in the Swiss Jura using the systems approach. The Aubonne karst aquifer drains towards two main springs at different altitudes. Three models with different structures w ...

Balancing current drive and heating in DIII-D high noninductive current fraction discharges through choice of the toroidal field

Holger Reimerdes

In order to maintain stationary values of the stored energy and the plasma current in a tokamak discharge with all of the current driven noninductively, the sum of the α-heating power and the power required to provide externally driven current must be equa ...

Experimental Evidence of Rotating Stall in a Pump-Turbine at Off-Design Conditions in Generating Mode

François Avellan, Mohamed Farhat, Vlad Hasmatuchi, Steven Roth, Francisco Botero

An experimental investigation of the rotating stall in reduced scale model of a low specific speed radial pump-turbine at runaway and turbine brake conditions in generating mode is achieved. Measurements of wall pressure in the stator are performed along w ...

Tidally driven multiscale pore water flow in a creek-marsh system

David Andrew Barry

Intertidal wetlands are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on three-dimensional, variably satur ...
