Sedimentary processes on an intertidal mudflat in the upper macrotidal Seine estuary, France

Sudden Clearing of Estuarine Waters upon Crossing the Threshold from Transport to Supply Regulation of Sediment Transport as an Erodible Sediment Pool is Depleted: San Francisco Bay, 1999

“…Regulation may also vary seasonally and fortnightly. For example, in San Francisco Bay and other estuaries, there is a seasonal cycle of sediment inflow during the wet season and winnowing and redistribution of sediment by tides and waves during the dry season (Deloffre et al 2005;Krone 1979;Lesourd et al 2003;Ryu 2003). Thus, suspended mass may be transport-regulated after delivery of sediment from the watershed and supply-regulated at the end of the dry season.…”

“…Thus, suspended mass may be transport-regulated after delivery of sediment from the watershed and supply-regulated at the end of the dry season. In addition, SSC in San Francisco Bay and other estuaries varies with the spring/neap tidal cycle (Brennan et al 2002;Grabemann et al 1997;Schoellhamer 2002;Wolanski et al 1995), and the depth of bed sediment reworking decreases during neap tides (Brennan et al 2002;Deloffre et al 2005). Thus, suspended mass may be transportregulated during neap tides and supply-regulated during spring tides.…”

Morphological responses of an estuarine intertidal mudflat to constructions since 1978 to 2005: The Seine estuary (France)

“…1c) is mainly made up of silty-clay particles, sometimes associated with fine or coarse sands (Hoyez and Cuvilliez, 2001;Lesourd et al, 2003;Deloffre et al, 2007). The sedimentary dynamics of this mudflat has been examinated for several decades (Avoine, 1981;Lesourd et al, 2001;Deloffre et al, 2005) as well as its hydrodynamics (Verney, 2006). This work has led to the modelling of the hydro-sedimentary evolution of the zone (Brenon, 1997;Le Hir et al, 2001).…”

Modeling sorting dynamics of cohesive and non-cohesive sediments on intertidal flats under the effect of tides and wind waves

“…River inflow has been reported to affect the flow field and the suspended sediment transport pattern and its influence on intertidal flats depends on the magnitude of discharge and associated sediment source (Zhou et al, 2014a). Based on field observations of the Seine estuary, Deloffre et al (2005) found that accretion of intertidal flats occurred during high river inflow and erosion during low river inflow. This trend might reverse over short time scales depending on local dynamics and specific estuarine conditions (e.g., Deloffre et al, 2006).…”
