Semi-empirical model for channel bed evolution due to lateral discharge withdrawal

Anton Schleiss, Burkhard Rosier

Side weirs and overtopable levees are widely used to increase flood routing along a channel or river. The lateral loss of water reduces the sediment transport capacity leading to the formation of a local sediment deposit close to the overflow. Since the ex ...

Meander dynamics: A nonlinear model without curvature restrictions for flow in open-channel bends

Koen Blanckaert

Despite the rapid evolution of computational power, simulation of meander dynamics by means of reduced and computationally less expensive models remains practically relevant for investigation of large-scale and long-term processes, probabilistic prediction ...

Flow and bathymetry in sharp open-channel bends: Experiments and predictions

Koen Blanckaert, Serban George Constantinescu

This paper focuses on experiments and simulations conducted in very sharp open-channel bends with flat and equilibrium bathymetry, corresponding to the initial and final phases of the erosion and deposition processes, respectively. The study of flow in cur ...

Hierarchy of models for meandering rivers and related morphodynamic processes

Paolo Perona

We review the importance of the physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof. Such models are hierarchically derived from a common and general mathematical framework and then analyzed with ...

Transnational concept for the provision of streambank erosion hazard information

John Beck

Streambank erosion is an aspect of flood hazards that has been largely neglected to date due to its complexity. The INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER) has recognized its importance by including this aspec ...

On the long-term behavior of meandering rivers

Paolo Perona

In spite of notable advances in the description of river morphodynamics, the long-term dynamics of meandering rivers is still an open question, in particular, regarding the existence of a possible statistical steady state and its scaling properties induced ...

Tidal landforms, patterns of halophytic vegetation and the fate of the lagoon of Venice

Andrea Rinaldo

We review recent advances in the study of tidal landforms and their embedded vegetation patterns within the lagoon of Venice, aiming at clues on the coevolution of their morphodynamic and ecological features. The observation and analysis of network and veg ...

Sand bars in tidal channels part 2. Tidal meanders

Andrea Rinaldo

Careful analysis of new field observations on the geometry of meandering tidal channels reveals that the values of meander wavelengths as well as curvatures, conveniently scaled by local channel width, fall within a fairly restricted range, suggesting the ...
