LSPIV implementation for environmental flow in various laboratory and field cases

Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different ...

Flood Management in a Complex River Basin with a Real-Time Decision Support System Based on Hydrological Forecasts

Javier García Hernández

During the last decades, the Upper Rhone River basin has been hit by several flood events causing significant damages in excess of 500 million Swiss Francs. From this situation, the 3rd Rhône river training project was planned in order to improve the flood ...

Sulfide oxidation and acid mine drainage formation within two active tailings impoundments in the Golden Quadrangle of the Apuseni Mountains, Romania

Linda Frei

Sulfidic mine tailings have to be classified as one of the major source of hazardous materials leading to water contamination. This study highlights the processes leading to sulfide oxidation and acid mine drainage (AMD) formation in the active stage of tw ...

Three-dimensional nonlinear seismic analysis of concrete faced rockfill dams subjected to scattered P, SV, and SH waves considering the dam-foundation interaction effects

Ali Seiphoori

In this study, the nonlinear seismic analysis of a typical three-dimensional concrete faced rockfill dam is reported. Three components of the Loma Prieta (Gilroy 1 station) earthquake acceleration time history are used as input excitation. The dam under st ...

Experimental parametric study for hydraulic design of PKWs

Anton Schleiss, Marcelo Leite Ribeiro

The implementation of a new type of labyrinth spillway, called PKW (Piano Key Weir) reveals as a performing alternative for increasing the overflow capacity of existing dams. The optimal hydraulic design of such structure is however not obvious due to the ...

Downstream relevance of reservoir management

Alfred Johny Wüest

The management of dams serves many purposes and goals all over the globe, and has important consequences for the downstream rivers and lakes. Among the more than 50,000 so-called large dams, the biggest are located in alpine regions. As a result, the water ...

Spillway discharge capacity upgrade at Gloriettes dam

Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel

In many countries dams are found to have insufficient flood discharge capacity with respect to updated design floods. Upgradig of spillway discharge capacity has therefore become a significant issue for operators of hydropower plants. The Gloriettes concre ...

Analysis of flow regime changes due to operation of large reservoirs on the Zambezi River

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

The Zambezi Basin, a semi-arid 1.4 Mio km2 catchment area spreading across eight countries, constitutes a highly complex system. With several large dams, namely Kariba, Cahora Bassa, Kafue Gorge and Itezhi-Tezhi, the basin’s hydrology is also influenced by ...

Toe protection for spill-through and vertical-wall abutments

Anton Schleiss, António Heleno Cardoso

This study addresses the design of riprap aprons as a scour countermeasure near abutments under clear-water conditions. It deals with the lateral extent of riprap aprons and the geometry of the scour hole prevailing at the apron edge. The study applies to ...

Dynamic analysis of anchored concrete linings of plunge pools loaded by high velocity jet impacts issuing from dam spillways

Anton Schleiss

A theoretical stochastic approach is presented for the structural analysis of plunge pool liners dynamically loaded by the impact of free-falling jets. Such an approach was used as the real behaviour of plunge pool liners is complex, and deterministic meth ...
