Muon Collider Forum report

Théodora Cohen Liechti, João Miguel das Neves Duarte, Andrea Wulzer, Wei Li, Xiao Wang, Christoph Herwig

A multi-TeV muon collider offers a spectacular opportunity in the direct exploration of the energy frontier. Offering a combination of unprecedented energy collisions in a comparatively clean leptonic environment, a high energy muon collider has the unique ...

Waves generated by ship convoy: Comparison of physical and numerical modeling with in-situ measurements

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Robin Amacher, Théodora Cohen Liechti

A part of the domestic waste of the city of Geneva (Switzerland) is transported with ship convoys on the Rhone River to the waste incineration station. These convoys generate waves, which partially endangers the stability of the river banks and the riparia ...

Wave-reducing Stern Flap on Ship Convoys to Protect Riverbanks

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Robin Amacher, Théodora Cohen Liechti

Inland navigable waterways are significant in cargo transport and leisure activities. In parallel, these channels and rivers often suffer from the ship traffic, as the generated waves may damage waterway banks, along with their riparian fauna. As a consequ ...

Influence of Hydropower Development on Flow Regime in the Zambezi River Basin for Different Scenarios of Environmental Flows

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

As the need for energy is increasing, the challenges in the future are to operate existing large hydraulic schemes in more sustainable ways and to develop future water resources projects that are able to achieve a better balance between environmental and s ...

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 ...

Pattern-oriented memory interpolation of sparse historical rainfall records

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

The pattern-oriented memory (POM) is a novel historical rainfall interpolation method that explicitly takes into account the time dimension in order to interpolate areal rainfall maps. The method is based on the idea that rainfall patterns exist and can be ...

Coupling satellite rainfall estimates and machine learning techniques for flow forecast: application to a large catchment in Southern Africa

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

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 ...

Influence of dam operation on water resources management under different scenarios in the Zambezi River Basin considering environmental objectives and hydropower

Théodora Cohen Liechti

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 ...

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 ...
