Stratigraphy of North Edisto Inlet, SC based on sediment cores and shallow seismic data (After Imperato et al. 1988).

delta is very similar to Bolivar Roads delta (see

; Siringan and Anderson
1993
, Rodriguez
et al. 1998). The coarsening upward nature of the
Barataria delta sequence is explained by the long-term
increase in tidal energy resulting from the enlarging
tidal prism (FitzGerald et al.
2004
) .
The similarities in facies architecture of the Texas
and Barataria coast ebb deltas result from similar
low-energy hydrographic regimes and the same overall
muddy character of the surrounding sedimentary envi-
ronments. These depositional systems contrast with
sand-rich ebb-tidal deltas in which the stratigraphy is
