Self-organization of tidal deltas

WebDec 19, 2024 · Tide-dominated deltas develop where a large range between the high and low tides leads to strong tidal currents. On these coasts, the wave height is moderate to low, and wave-induced currents along the coast are weak. These deltas resemble estuaries because of their embayed setting of salt marshes, swamps, and tidal flats.

Tidal fluxes are inherently linked to the tidal prism (i.e., the volume of water that enters the delta during one tidal cycle), which, to a first approximation, can be simply computed by multiplying the planimetric submerged area of the delta by the local tidal amplitude (8). Therefore, critical for delta dynamics WebSep 9, 2024 · In a wave-dominated delta, the movement of waves controls a delta's size and shape.
