Characteristics of Suspended Solids Concentration in Well-Mixed Estuary

Clay fabric of fluid-mud deposits from laboratory and field observations: Potential application to the stratigraphic record

“…In the area of the river mouth, the maximum tidal range during spring tide is up to 5 m, and salt-water intrudes up to 29 km upstream from the river mouth (Futawatari et al, 1992). The overall geometry and relative intensity of tides and waves at the mouth (Fujimoto and Watanabe, 1988;Futawatari et al, 1992) indicate that the estuary is tide-dominated. The nature of spatial and temporal variations in salinity throughout the estuary indicates that a salt wedge is not developed (Futawatari et al, 1992).…”

The nature of spatial and temporal variations in salinity throughout the estuary indicates that a salt wedge is not developed (Futawatari et al, 1992). The turbidity maximum of the estuary is well developed from the river mouth to about 20 km upstream, and is characterized by a high concentration of suspended sediment (up to 30 g/L), resulting in the development of fluid mud (Futawatari et al, 1992).…”
