Fine sediment transport into the hyperturbid lower Ems River: The role of channel deepening and sediment-induced drag reduction

Van Maren, D.S. (author), Winterwerp, J.C. (author), Vroom, J. (author)

Deepening of estuarine tidal channels often leads to tidal amplification and increasing fine sediment import. Increasing fine sediment import, in turn, may lower the hydraulic drag (due to a smoother muddy bed and/or sediment-induced damping of turbulence), and therefore, further strengthen tidal amplification, setting in motion a process in...

Estimation of bed protection damage using numerical flow modelling

Hoan, N.T. (author), Booij, R. (author), Hofland, B. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)

The current research is aimed at evaluating the applicability of a numerical flow model to predict bed damage. First, an experimental study was carried out to get more inside into the relation between flow forces acting on a bed and the bed response (damage). The experiments were then used as the basis for the evaluation. Second, the flow was...

Swell across the continental shelf

Ardhuin, F. (author)

The transformation of surface gravity waves propagating through shallow regions is investigated with extensive field data from the North Carolina continental shelf. A spectral energy balance equation is derived for a bidimensional bottom topography with random small-scale irregularities, in which bottom friction is introduced heuristically whith...

A sensitivity analysis applied to morphological computations

De Vries, M. (author)

In river engineering morphological predictions have to be made to study the implications of changes in a river system due to natural causes or human interference. It regards here time-depending processes. Characteristic parameters of the river have to be forecasted both in time and space. The morphological processes, however, are extremely...
