Distinct patterns of interactions between vegetation and river morphology

Van Oorschot, M. (author), Kleinhans, M. (author), Middelkoop, H. (author), Geerling, G. (author), Buijse, T. (author), Mosselman, E. (author)

Modelling vegetation and morphodynamics is often one-way traffic that either takes into account the effect of vegetation on morphodynamics or vice versa. The few models that do incorporate an interaction have until now represented vegetation as cylinders causing hydraulic resistance that do not change over time. We coupled a morphodynamic model...

Numerical simulations of upstream and downstream overdeepening

Van der Meer, C. (author), Mosselman, E. (author), Sloff, C.J. (author), Jagers, B. (author), Zolezzi, G. (author), Tubino, M. (author)

Local geometrical perturbations of alluvial channels can generate a pattern of non-migrating bars and pools. This phenomenon is known as “overdeepening”, because the pools locally enhance the scour in river bends. Overdeepening occurs only downstream of a perturbation if the channel is in the subresonant and subcritically damped regime, which...

A new approach to river bank retreat and advance in 2D numerical models of fluvial morphodynamics

Spruyt, A. (author), Mosselman, E. (author), Jagers, B. (author)

River bank retreat and advance are modes of morphological evolution in addition to bed level changes and changes in bed sediment composition. They produce planform changes such as width adjustment and meander bend migration. However, their reproduction in a 2D numerical model still remains a challenge. Defining bank-lines along the nearest grid...

Numerical nonlinear analysis of alternate-bar formation and overdeepening under superresonant conditions (poster)

Verbruggen, W. (author), Mosselman, E. (author), Zolezzi, G. (author), Sloff, C.J. (author)

Local geometrical perturbations in alluvial channels can generate a pattern of alternate bars called ‘overdeepening’. Previous linear analyses and laboratory experiments showed that these bars arise downstream of perturbations in the relatively narrow and deep channels corresponding to subresonant conditions, but both upstream and downstream of...

Bifurcation dynamics and avulsion duration in meandering rivers by one-dimensional and three-dimensional models

Kleinhans, M.G. (author), Jagers, H.R.A. (author), Mosselman, E. (author), Sloff, C.J. (author)

At river bifurcations, water and sediment are divided over two branches. The dynamics of the bifurcation determine the long-term evolution (centuries) of the downstream branches, potentially leading to avulsion, but the dynamics are poorly understood. The long-term evolution can only be studied by one-dimensional models because of computational...

Veldexperiment in de Hooge Raam: Winst voor beekherstel én wetenschap

Eekhout, J.P.C. (author), Hoitink, A.J.F. (author), Mosselman, E. (author), Kits, M. (author), Talsma, M. (author)

In de beek de Hooge Raam is een beekherstelproject gekoppeld aan een uniek veldexperiment. Het doel van het veldexperiment was om over een periode van drie jaar de temporele morfodynamiek te volgen van een rechte beekloop met een breed en ondiep dwarsprofiel. Ongeveer 8 maanden na aanleg zijn alternerende banken ontstaan. In eerste instantie...

Detailed simulation of morphodynamics: 3. Ripples and dunes

Nabi, M. (author), De Vriend, H.J. (author), Mosselman, E. (author), Sloff, C.J. (author), Shimizu, Y. (author)

We present a 3-D physics-based high-resolution modeling approach to the dynamics of underwater ripples and dunes. The flow is modeled by large eddy simulation on a Cartesian grid with local refinements. The sediment transport is modeled by computing pickup, transport over the bed, transport in the water column, and deposition of rigid spherical...

Experimental and numerical evidence for intrinsic nonmigrating bars in alluvial channels

Crosato, A. (author), Mosselman, E. (author), Desta, F.B. (author), Uijttewaal, W.S.J. (author)

Alternate bars in straight alluvial channels are migrating or nonmigrating. The currently accepted view is that they are nonmigrating if the width-to-depth ratio is at the value of resonance or if the bars are forced by a persistent local perturbation. We carried out 2-D numerical computations and a long-duration mobile-bed flume experiment to...
