Comparison of hydraulic design equations for Type A Piano Key Weirs
Anton Schleiss, Michael Pfister
Piano Key weirs (PKWs) are a hydraulically attractive alternative to linear overflow weirs, increasing the unit discharge at the unregulated spillway inlet for similar heads and spillway widths. This advantage, allowing for operation of dam reservoirs on e ...
2013Influence of dam operation on water resources management under different scenarios in the Zambezi River Basin considering environmental objectives and hydropower
Worldwide, almost 50,000 dams over 15 m height have been built during the last six decades with an aggregated storage capacity of 6,000 km3. The fact that large dams, by increasing irrigation and hydroelectricity production, can sustain development and red ...
EPFL2013Perimeter and boundary flow control in multi-reservoir heterogeneous networks
In this paper, we macroscopically describe the traffic dynamics in heterogeneous transportation urban networks by utilizing the Macroscopic Fundamental Diagram (MFD), a widely observed relation between network-wide space-mean flow and density of vehicles. ...
Elsevier2013Influence of dam operation on water resources management under different scenarios in the Zambezi River Basin considering environmental objectives and hydropower
The hydropower potential in Africa is only very few exploited. The large rivers like Zambezi River still have considerable possibilities for installing further hydropower projects including the creation of reservoirs by large dams. The main African watersh ...
EPFL - LCH2013Debris-Blocking Sensitivity of Piano Key Weirs under Reservoir-Type Approach Flow
Anton Schleiss, Michael Pfister, Blake Tullis
The collection of floating woody debris at flow control structures, such as spillways and weirs, can potentially result in reduced discharge efficiency (higher upstream head for a given weir discharge). Compared to less hydraulically-efficient control stru ...
Asce-Amer Soc Civil Engineers2013Influence of pumped-storage operation on reservoir sedimentation
Anton Schleiss, Giovanni De Cesare, Michael Müller
In Europe, renewable energy sources are rapidly growing but are often linked to a highly volatile production, as for solar and wind energy. Pumped-storage plants have become very important since they can ensure grid stability and safe power supply at any m ...
2013Coupling satellite rainfall estimates and machine learning techniques for flow forecast: application to a large catchment in Southern Africa
Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Théodora Cohen Liechti
Accurate river flow forecasting is an important asset for stream and reservoir management, being often translated into substantial social, economic and ecological gains. This contribution aims at coupling satellite rainfall estimates and machine learning t ...
TPU2013Optimizing the operation of the Qingshitan Reservoir in the Lijiang River for multiple human interests and quasi-natural flow maintenance
For reservoir operation, maintaining a quasi-natural flow regime can benefit river ecosystems, but may sacrifice human interests. This study took the Qingshitan Reservoir in the Lijiang River as a case, and developed an optimization model to explore a trad ...
2012Rainfall-discharge model of the Aubonne karst watershed (Swiss Jura)
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 ...
2012Hydraulic 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 ...
