The U.S. Army Corps of Engineers Bay Model is a working hydraulic scale model of the San Francisco Bay and Sacramento-San Joaquin River Delta System. While the Bay Model is still operational, it is no longer used for scientific research but is instead open to the public alongside educational exhibits about Bay hydrology.
A river delta is so named because the shape of the Nile Delta approximates the triangular uppercase Greek letter delta.The triangular shape of the Nile Delta was known to audiences of classical Athenian drama; the tragedy Prometheus Bound by Aeschylus refers to it as the "triangular Nilotic land", though not as a "delta".

An aerial view of the model. The Mississippi River Basin Model was a large-scale hydraulic model of the entire Mississippi River basin, covering an area of 200 acres. [1] It is part of the Waterways Experiment Station, located near Clinton, Mississippi. The model was built from 1943 to 1966 and in operation from 1949 until 1973.
One modeling begins, sea level rise, storm surge, and flood flows should be taken into account with regards to both the North Delta intakes and South Delta pumps. The modeling should also include a variety of tunnel operational scenarios in regards to different levels of water quality and diminished amount of river inflow.
The modern configuration of the Pearl River Delta emerged during the second marine transgression, which took place approximately 7500 years ago. [3] To elucidate the factors driving the evolution of the present delta, a three-stage evolutionary model has been proposed.

On the other hand, hydraulic models require the gathering of a lot of data related to river geometry and morphology and consume a lot of computer resources in order to solve the equations numerically. [17] [18] [19] However, semi-distributed models such as Muskingum–Cunge family procedures are also available. Simple physical concepts and ...
The modern Mississippi River Delta formed over the last approximately 4,500 years as the Mississippi River deposited sand, clay and silt along its banks and in adjacent basins. The Mississippi River Delta is a river-dominated delta system, influenced by the largest river system in North America.
