Seasonal, Neap-spring and Tidal Variation of Cohesive Sediment Concentration in the Scheldt Estuary, Belgium

A geometric method to study water and sediment exchange in tidal harbors

“…The horizontal gradient in the Lower Sea Scheldt in front of Deurganckdok, combined with a tidal excursion of the salinity front, yields a small tidal salinity variation. Fettweis et al (1998) found an average tidal salinity amplitude of 4.5 ppt at Prosperpolder, a measurement station downstream of Deurganckdok. The salinity in the dock also has a tidal salinity variation, which lags behind to the salinity in the Scheldt.…”

Control of sediment deposition rates in two mid-Atlantic Coast tidal freshwater wetlands

“…Zhuraleva and Morozova (1999) found that the turbidity maximum usually occurred at a salinity of approximately 2 in the Lower Dnieper River, Russia. The turbidity maximum may shift seasonally as a result of freshwater discharge (Fettweis, Sas, & Monbaliu, 1998), and well-developed turbidity maxima tend to be established during periods of low river discharge (Nichols & Biggs, 1985). If the freshwater/salt water interface was located near Gleason during the study period, the turbidity maximum would have provided large amounts of suspended sediment that was not available at the Walkerton site located 19 km upriver where the fluvial influence was greater.…”

Estuarine Turbidity Maxima and Variations of Aggregate Parameters in the Cam-Nam Trieu Estuary, North Vietnam, in Early Wet Season

“…Because of the strong influences of marine water, tide and river discharge, the occurrence of ETMs is complex and difficult to predict [1,2]. They are trapping a lot of suspended matter and encompass a huge range of SPM concentrations with maximum values from less than 100 mg L −1 like in the Kennebec Estuary, USA [3,4] to >200 g L −1 like in the Severn Estuary, UK [5].…”
