Moreover, mouth bar deposits offer a strategic location for the research projects regarding estuarine and delta restoration which makes them ideal for studying the effects of river sediment reduction and relative sea level rise and for estimating the evolution, including land loss and inundation, of the river deltas.
The older sequence of the deltaic deposits traces back to the first cycle of marine regression and transgression during the last interglacial period, which occurred between 130,000 and 115,000 years ago. [24] The more recent sequence of the deltaic deposits pertains to the second cycle of marine regression and transgression.
A tidal freshwater delta [33] is a sedimentary deposit formed at the boundary between an upland stream and an estuary, in the region known as the "subestuary". [34] Drowned coastal river valleys that were inundated by rising sea levels during the late Pleistocene and subsequent Holocene tend to have dendritic estuaries with many feeder tributaries.
The Mississippi River major deltaic cycle began over 7,000 years ago, eventually forming six delta complexes which are major depositional elements of a delta plain. The Mississippi River Delta complexes consist of smaller areas known as delta lobes, which contain the basins and other natural landscapes of the coastline. [13]
A cuspate deltaic lobe involves the creation and subsequent abandonment of deltaic lobe cusps to create unique linear delta formations. The cuspate deltaic lobe is defined by its abrupt rate of discharge from river to body of water, and the creation of multiple cusp systems built up into separate but active distributaries.
The Gran Desierto sand sheets and dunes are located atop deltaic deposits of the Pleistocene Colorado River. The lower Colorado River was captured by the Gulf of California 1.2 million years before present. [9] This event places an upper bound on the age of the Gran Desierto with the Colorado's major clastic sediment sources.
