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. WebNov 5, 2024 · The self-organization theory has proven to be an effective method to describe the beach topography evolution (e.g., the formation of beach cusps and crescent sandbars) (Coco et al., 2000; Stive and Reniers, 2003; Smit et al., 2008; Werner and Fink, 1993 ).
