Component: Geoform

Unique Identifier: 77

Geoform Origin Geologic
Geoform Delta
Geoform Type Flood Tidal Delta

Definition Equivalent to an Ebb Tidal Delta, except that this delta occurs on the landward side of a tidal inlet (modified from Boothroyd et al. 1985; Davis 1994; Ritter et al. 1995). Flood tides transport sediment through the tidal inlet, over a flood ramp where currents slow and dissipate before entering the lagoon (Davis 1994). Generally, flood tidal deltas along microtidal coasts are multi-lobate and unaffected by ebbing currents (modified from Davis 1994).
