Bottom-Pressure Development Due to an Abrupt Slope Reduction at Stepped Spillways

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

Fluctuating bottom-pressures on stepped chutes are relevant for the spillway design. An abrupt slope reduction causes a local alteration of the bottom-pressure development. Little information is available regarding the air–water flow properties near an abr ...

Searching for continuous phase transitions in 5D SU(2) lattice gauge theory

João Miguel Augusto Penedones Fernandes, José Pedro Gamito de Saldanha Calado Matos, Adrien Florio

We study the phase diagram of 5-dimensional SU(2) Yang-Mills theory on the lattice. We consider two extensions of the fundamental plaquette Wilson action in the search for the continuous phase transition suggested by the 4 + epsilon expansion. The extensio ...

Bottom pressure characteristics in a stilling basin downstream of a stepped spillway for two different chute slopes

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Ivan Stojnic

In the last decades numerous stepped spillways were built, mostly on the downstream face of roller compacted concrete (RCC) dams. Stilling basins are often used as an energy dissipater. Although the hydraulics of stepped chutes was extensively investigated ...

Redesigning Water Distribution Networks Using a Guided Evolutionary Approach

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos

The paper describes and discusses the application of a guided evolutionary approach for the optimization of water distribution networks. Initially developed for the Battle of the Water Networks II (BWN-II), the approach was adapted and improved for competi ...

Hydraulic Jump Downstream of a Stepped Chute: An Experimental Study

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Ivan Stojnic

The number of stepped spillways significantly increased in the past decades. Among other reasons, this is due to their energy dissipation potential leading to a reduction of the residual energy at the toe of the spillway. To date, only fragmentary designed ...

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, ...

Can satellite based pattern-oriented memory improve the interpolation of sparse historical rainfall records?

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

Ther is a standing challeng in obtaining long localized records of rainfall data in many large river basins of the developing world. Recent spaceborne instrumentation offers a constente source of rainfall information, but this information covers only a rel ...

Effect of an abrupt slope change on air entrainment and flow depths at stepped spillways

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

Several stepped spillways have been built in recent decades, mostly integrated in the downstream faces of roller compacted concrete dams. Among them, only a few have changing bottom slopes. Comprehensive information on the effect of a slope change on the f ...

Hydraulic–hydrologic model for water resources management of the Zambezi basin

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

The paper focuses on the development of the hydraulic–hydrological model used to simulate water resources management scenarios in the Zambezi River basin. The main challenges of the implementation of the model are the scarcity of continuous reliable discha ...

Hydrological modelling of the Zambezi River Basin taking into account floodplain behaviour by a modified reservoir approach

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

Floodplains are regions of great interest for environmental assessment as they constitute important ecological reserves and contribute efficiently to natural flood attenuation. However, the implementation of a model describing the basic hydrological behavi ...

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 ...

Bemessung von klassischen Tosbecken unterhalb von Treppenschussrinnen

Anton Schleiss, Giovanni De Cesare, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Ivan Stojnic

Aufgrund des Fortschritts im Talsperrenbau mit Walzbeton (RCC) werden weltweit häufig Treppenschussrinnen erstellt. Nach jeder Schussrinne ist ein hydraulisches Bauwerk zur Energiedissipation vorzusehen, beispielsweise ein Tosbecken. Obwohl die Hydraulik v ...

Entrainement de bois flottant dans un déversoir a crête standard avec piliers: Influence des caractéristiques de bois flottant en probabilités de blocage

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Paloma Furlan

Spillways are safety elements of dams that allow to release floods. They spill water to avoid overtopping with its potential structural damages at the dam and the downstream environment. Nevertheless it may be unsafe to assume that a flood only carries cle ...
