The shallows around the point bar can become treacherous when the stream is rising. As the water depth increases over the shallows of the point bar, the vortex flow can extend closer toward the convex bank and the water speed at any point can increase dramatically in response to only a small increase in water depth.
The Sphinx water erosion hypothesis is a fringe claim, contending that the Great Sphinx of Giza and its enclosing walls show erosion consistent with precipitation.
Globiferous pedicellariae also end in a three-valved claw-like grasping appendage, like they do in ophicephalous pedicellariae, but they are much larger. [19] [22] The valves are connected to each other by a distinctive circular membrane around 4 to 5 mm (0.16 to 0.20 in) in diameter. They are pinkish-white to yellowish-white in color with a ...
Robert Milton Schoch is an American associate professor of Natural Sciences at the College of General Studies, Boston University.Following initial work as a vertebrate paleontologist, Schoch co-authored and expanded the fringe Sphinx water erosion hypothesis since 1990, and is the author of several pseudohistorical and pseudoscientific books.
Therefore, bulk erosion rates are difficult to control since it is not zero order. [1] To determine whether a polymer will undergo surface or bulk erosion, the degradation rate of the polymer in water (how fast the polymer reacts to water) and the rate of diffusion of water penetrating through the material must be considered. If the degradation ...

Bioerosion describes the breakdown of hard ocean substrates – and less often terrestrial substrates – by living organisms. Marine bioerosion can be caused by mollusks, polychaete worms, phoronids, sponges, crustaceans, echinoids, and fish; it can occur on coastlines, on coral reefs, and on ships; its mechanisms include biotic boring, drilling, rasping, and scraping.
Incredible video emerged this week showing severe erosion of homes in Jupiter Inlet Colony in Jupiter, Florida, north of Palm Beach. About 70% of the county's 47 miles of coastline is considered ...
