Meandering rivers and streams are a common planform in the world’s populated areas. Furthermore the recent increased focus on renaturalization projects has lead policy makers to also consider the partial remeandering of previously trained rivers. Economic ...
The temporal variability of streamflows is a key feature structuring and controlling ecological communities and ecosystem processes. The magnitude, frequency and predictability of streamflows, and thus of velocity and near-bed shear stress fields, control ...
Hydrodynamical, morphodynamical and ecological river processes and their multiple linkages occur in an infinity of different configurations and over a wide range of spatial and temporal scales. This paper illustrates a research methodology that consists in ...
High-head storage hydropower plants operate their turbines during periods of high energy demand. The starting and stopping of turbines results in rapid fluctuations of discharge and water levels in rivers called hydropeaking, which are unfavorable from an ...
Many alpine torrents convey regularly debris flows of high destructive hazard. After several granular events observed in Bruchji?s torrent near the Blatten village in the Swiss Alps, it was decided to manage the risk of similar debris flows by designing an ...
In the framework of a research project focusing on mitigation measures for hydropeaking, a lateral embayment at the channel bank is studied as a fish refuge. Systematic experiments with different refuge configurations were carried out. The basic configurat ...
High-head storage hydropower plants mainly operate their turbines during periods of high energy demand. The sudden starting and stopping of turbines (hydropeaking) lead to highly unsteady flow in channels and rivers. Besides hydropeaking, other anthropogen ...
[1] The theory of stochastic differential equations driven by multiplicative Markovian dichotomous noise and a number of geomorphological relationships of river basins are used to investigate the geomorphological patterns of the width of riparian zones and ...
We investigate the entrainment, deposition and motion of coarse spherical particles within a turbulent shallow water stream down a steep slope. This is an idealization of bed-load transport in mountain streams. Earlier investigations have described this ki ...
We perform an analysis of the observational morphological structure of a tidal landscape aimed at examining key assumptions on the geomorphological evolution of wetlands, lagoons, estuarine areas and tidal environments in general. The issues addressed pert ...
