stratigraphy are similar. The Mississippi Delta complex, Nile
Delta, Niger Delta, São Francisco Delta, Klang Delta, and
Fly Delta are examples of large open coastal deltas (Allen,
1970; Coleman et al., 1970; Gould, 1970; Summerhayes
et al., 1978; Dominguez, 1996; Baker et al., 2009). Such
deltas have been classified as to their plan geometry in
response to their hydrodynamic setting as fluvial-dominated
deltas, tide-dominated deltas, and wave-dominated deltas
(Galloway, 1975) or by their depositional architecture and
facies (Postma, 1990). For completeness in the descriptions
of deltas, the reader is referred to geomorphic and stratigraphic descriptions of such open coastal deltas in Scruton
Deltas, Figure 2 Idealized diagram showing a range of estuary types, from an incised single valley to rias, a flooded valley on
a coastal plain, a barred estuarine coastal lagoon and a compound estuary, and the occurrence of intra-estuarine deltas (black)
therein.
Deltas, Figure 3 Idealized diagram showing the dual concepts of an estuary within a large delta and a delta within a large estuary
(or an intra-estuarine delta). In each example, the field of salinity is freshwater ¼ black, brackish water ¼ gray, and marine
water ¼ white.
