About the project
This study focusses on the physical mechanisms determining the hydro- and morphodynamic effects of LTD construction, including the (re-)generation and evolution of subaqueous dunes. Polystyrene granulates will be used in physical scale experiments designed to study the effects of the geometrical properties of the gaps between successive LTDs. Moreover, a unique large-scale, high-resolution morphological dataset will be analysed to obtain valuable insights into dune (re-)generation in lowland rivers controlled by humans. Finally, the potential of a state-of-the-art numerical model (Delft3D) to study the hydrodynamics and morphodynamics around artificial structures such as LTDs will be established. In this context, the importance of advective fluxes relative to turbulence-induced transport is subject to investigation, both experimentally and numerically. Read two-pages overview >>
