Winds of opportunity: The effects of wind on intertidal flat accretion

Colosimo, I. (author), van Maren, D.S. (author), de Vet, P.L.M. (author), Winterwerp, J.C. (author), van Prooijen, Bram (author)

Intertidal ecosystems are threatened by sea level rise and anthropogenic pressures. Understanding the processes controlling the morphodynamic developments of tidal flats is crucial for sustainable management of these systems. Analysis of three extensive fieldwork campaigns carried out on two adjacent mudflats fringing the Dutch Western Wadden...

The Changjiang Estuary: A highly turbid estuary in transition

Lin, J. (author)

Estuaries are the core area of land-sea interactions and have significant ecological and economic value. In estuaries, hydrodynamics and sediment dynamics are the crucial processes governing geomorphology, navigability, and primary production. Since the turn of the 20th century, increased human activities (e.g., damming, dredging, and...

Source to sink reconstruction of a Holocene Fjord‐infill: Depositional patterns, suspended sediment yields, wind‐induced circulation patterns and trapping efficiency for Lake Strynevatnet, inner Nordfjord, Norway

Storms, J.E.A. (author), Beylich, Achim A. (author), Hansen, Louise (author), Waldmann, Nicolas (author)

This paper reconstructs the sedimentation volumes and patterns, suspended sediment yields, wind‐induced circulation patterns and sediment trapping efficiency of Lake Strynevatnet, western Norway as an integrated source to sink system. The lake became deglaciated ca 11 ky cal bp, with glacio‐isostatic uplift isolating the basin from the nearby...

An integrated optic and acoustic (IOA) approach for measuring suspended sediment concentration in highly turbid environments

Lin, J. (author), He, Qing (author), Guo, Leicheng (author), van Prooijen, Bram (author), Wang, Zhengbing (author)

Accurate measurement of suspended sediment concentration (SSC) in highly turbid environments has been a problem due to optical or acoustic signal saturation and attenuation. The saturation returns a limited measurement range, and the attenuation raises an ambiguity problem that a low optical or acoustic output could mean a low or a high SSC....

The Effect of Small Density Differences at River Confluences

van Rooijen, Erik (author), Mosselman, E. (author), Sloff, C.J. (author), Uijttewaal, W.S.J. (author)

Remarkable 3D flow structures occur at river confluences with small density differences due to differences in sediment concentration or temperature. We explain these by comparing numerical simulations for an idealized confluence with aerial photographs of several river confluences where color differences express the pattern of density...

Can the Scheldt River Estuary become hyperturbid?: A model analysis of suspended sediment concentrations and transport in response to channel deepening

Dijkstra, Y.M. (author), Schuttelaars, H.M. (author), Schramkowski, G.P. (author)

We investigate the hypothesis by Winterwerp and Wang (Ocean Dyn 63:1279–1292, 2013) that channel deepening in the Scheldt River Estuary could lead to a large increase in suspended sediment concentrations, with subsequent severe consequences to primary production and navigation. To this end, we use an idealised model to investigate the long...

The mean suspended sediment concentration profile of silty sediments under wave-dominant conditions

Zuo, L. (author), Roelvink, D. (author), Lu, Yongjun (author)

Suspended sediment concentration (SSC) is one of the fundamental topics in sediment study. The parameterization of the SSC profile of silty sediments is still under-researched. This study focuses on the mean SSC profile for silty sediments under non-breaking wave-dominant conditions. First, inspired by a 1DV model, different types of the...
