Synergies entre la production hydroélectrique et la protection contre les crues : cas d'étude de la Sihl en Suisse

Anton Schleiss, Pedro Filipe De Almeida Manso, Frédéric Jordan, Fränz Zeimetz

Située à la confluence de deux cours d'eau – la Limmat et la Sihl – la ville de Zurich a toujours dû faire face aux crues. Suite aux crues de 2005, un projet de dérivation de la Sihl vers le lac de Zurich en amont de la ville a été lancé. En alternative à ...

Swiss Rainfall Mass Curves and their Influence on Extreme Flood Simulation

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme flood estimates for dam safety are routinely obtained from hydrologic simulations driven by selected design storms. The temporal structure of such design storms can be obtained from Rainfall Mass Curves (RMCs), which are adimensionalized curves of ...

New Approach to Identifying Critical Initial Conditions for Extreme Flood Simulations in a Semicontinuous Simulation Framework

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme flood simulation with synthetic extreme precipitation events raises unavoidable questions about the choice of initial conditions. State-of-the-art extreme flood estimation frameworks propose to address these questions with the help of semicontinuou ...

Development of a methodology for extreme flood estimations in alpine catchments for the verification of dam safety

Fränz Zeimetz

In the context of dam safety, reliable safety flood estimation methods are necessary to guarantee a sufficiently designed spillway capacity. Todayâ s state of the art allows to approach this topic under different angles. Statistical extrapolations are com ...

Relevance of the correlation between precipitation and the 0 C isothermal altitude for extreme flood estimation

Anton Schleiss, Javier García Hernández, Bettina Schaefli, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme floods are commonly estimated with the help of design storms and hydrological models. In this paper, we propose a new method to take into account the relationship between precipitation intensity (P) and air temperature (T) to account for potential ...

Impacts du changement climatique sur la production hydroélectrique alpine : comment une nouvelle retenue à Oberaletsch pourrait garantir la gestion durable des installations existantes

Anton Schleiss, Pedro Filipe De Almeida Manso, Fränz Zeimetz, Jonathan Fauriel

Suite à décision du Conseil Fédéral de sortir du nucléaire, l’hydroélectricité suisse jouera un rôle central pour réussir la transition énergétique. Cependant, le changement climatique semble avoir un impact négatif sur la production hydraulique à long ter ...

Extreme flood estimations on a small alpine catchment in Switzerland, the case study of Limmerboden

Anton Schleiss, Javier García Hernández, Fränz Zeimetz

In this paper, a case study on the estimations of extreme floods is described. The watershed chosen for the analysis is the catchment of the Limmernboden dam situated in Switzerland. Statistical methods and the simulation based "Probable Maximum Precipitat ...

Characterization of structural disturbances in peats by X-ray CT-based density determinations

Alexandre Buttler, Pascal Turberg, Fränz Zeimetz

Bulk densitywas determined indirectly in peat samples by X-ray computed tomography (X-ray CT) and compared with density values obtained by standard laboratory methods. Five Histosols were collected in the same cut-over peatland, representing various degree ...
