Accurate estimation of bed shear stress is crucial for understanding sediment transport and morphodynamic processes in fluvial and environmental flows. Shear plates offer a direct measurement approach that avoids the restrictive flow assumptions of many indirect methods. However, their broader use has been limited by misconceptions and concerns about measurement uncertainty. This study addresses these challenges by applying un...

Hydrodynamics of vegetated flows plays an essential role in fluvial morphodynamics since vegetation leads to significant changes in local bed load fluxes. The interactions between bed roughness and vegetation modify the near-bed flow field, hampering the application of bed load transport models, which rely on accurate estimation of bed shear stress. This paper addresses the impact of sparse arrays of rigid emergent vegetation...

Natural levees are wedge-shaped morphological features developing along the boundaries of mass flows. When they form in fluvial landscapes, they can have multiple implications for river management of trained inland rivers. This paper summarizes the present knowledge in regard to the formation and evolution of so-called fluvial levees of trained inland river sections and provides novel hypotheses in regard to the significance o...

The Pacific oyster ( Magallana gigas ) is an invasive species in the Wadden Sea transforming parts of it permanently. M. gigas , as an ecosystem engineer, builds reef structures that are characterized by highly complex and variable surfaces consisting of densely packed, sharp-edged individuals connected with cement-like bonds. To investigate the interactions between reef structure, shape and formation and wave as well as tidal...
