The low-lying delta plain
is only about 1 metre above present sea level.
The lithofacies include: 1) Thick bedded sandstone (DLF-I), representing deposition in a delta front setting, 2) Channelized sandstone and alternate black shale (DLF-2), deposited in a delta plain
setting, 3) Carbonaceous clays (DLF-3), indicating deposition in pro delta setting, and 4) Laterite (DLF-4) representing prolonged exposure of the platform under oxidizing conditions.
Flood risk of natural and embanked landscapes on the Ganges-Brahmaputra tidal delta plain
5 m above Canadian Gravimetric Geoid at Reindeer Channel exceeds maximum elevations of the outer delta plain
and suggests that the surge inundated most alluvial terrain within 20 to 30 km of the coast.
The Kernave Fm has been interpreted as shallow marine tidal flat and tidal bar deposits intercalated by tide-dominated deltaic formations (Kleesment 1997) or as being deposited in a tide-dominated deltaic setting that consists of prodelta mudstones, delta front tidal bar deposits intercalated by delta plain
tidal flat and distributary channel deposits, which is also the characteristic depositional environment for the Arukula Fm (Tanavsuu-Milkeviciene & Plink-Bjorklund 2009).
The Arlington Archosaur Site preserves a diverse coastal ecosystem within the interbedded coals, mudstones and sand lenses of a delta plain
Bangladesh lies in a vast fertile delta plain
fed by three of the largest rivers in the world, the Ganges, the Brahmaputra, and the Meghna.
There's just not enough sediment to sustain the delta plain
," study author Michael Blum of Louisiana State University in Baton Rouge, told National Geographic News.
Third, formed more than 15,000 years ago from an ice sheet during the last interglacial period, the Mississippi Delta plain
was "influenced by variations in sediment and meltwater discharge" (Rittenour, Blum, & Goble, 2007).
Along the Louisiana coast, in the delta plain
, much of the land is only a few feet above sea level.
In fact, the estuaries in the delta plain
are considered perhaps the most productive in the country.
On southern Roberts Bank, this sediment distribution pattern changes from a dominant sandy delta plain
that continues and coarsens well out onto the delta slope, but becomes finer grained at the base of the slope (Fig.
