Dec 20, 2021 · The ebb shield is the flood-tidal deltas equivalent of the terminal lobe and helps to divert ebb-currents along the margins of the flood-tidal delta. The flood currents follow the shallowing flood ramp and the flood channels that continue from the flood ramp.

Ebb-tidal delta. The evolution of the ebb-tidal delta of the Eastern Scheldt between the 16th and 20th century is mostly governed by the continuous increase in tidal prism after the 1530 storm event.

Jan 14, 2021 · An ebb-tidal delta is the giant pile of sand located at the mouth of a tidal inlet like this one. This may not sound glamorous, but understanding the way it moves around is extremely important for ensuring safe navigation and for predicting erosion and flooding of adjacent coasts.

Ebb strength: The EBB CURRENT at the time of maximum velocity. Ebb tidal delta: The bulge of sand formed at the SEAWARD mouth of TIDAL INLETS as a result of interaction between tidal currents and waves.

Jan 1, 2014 · Tidal deltas at inlets develop as flood deltas (landward of inlet) and ebb deltas (seaward). The more common delta—the flood delta—may range in shape from irregular sand shoals to the typical deltoid shape (Fig. 1).

Dec 20, 2021 · There is usually a distinct ebb-dominated current (i.e. averaged over the tide the flow is in the ebb-direction) over the outer delta, and often there are flood channels near the tips of the islands. In the Wadden Sea, well-developed flood deltas are hardly found (the entire basin acts as a flood delta, and the corresponding flood-residual ...

Nov 16, 2019 · Two different types of cyclic behavior were modeled, namely, ebb tidal delta breaching and outer delta breaching. The typical time scale of modeled cyclic behavior generally increases with increasing tidal prism and decreasing littoral drift.

Jan 1, 2013 · The ebb-tidal delta has segregated areas of landward versus seaward sediment transport that are controlled primarily by the way water enters and discharges from the inlet as well as the effects of wave-generated currents.

Dec 20, 2021 · The volume of sand stored in the ebb-tidal delta has empirically been related to the tidal prism of the back-barrier system (Fig. 9.21). The relationship in Fig. 9.21 was first derived for outer deltas in the USA and reads:

Based on the historical development combined with specific information of the tidal inlet, ebb-tidal delta, channel-shoal interaction, sediment exchange and the lessons learnt. The Rhine-Meuse-Scheldt delta, also called the south-western delta of the Netherlands, is shown in the figure.
