In geology, a bed is a layer of sediment, sedimentary rock, or volcanic rock "bounded above and below by more or less well-defined bedding surfaces". [1] A bedding surface or bedding plane is respectively a curved surface or plane that visibly separates each successive bed (of the same or different lithology ) from the preceding or following bed.
The Exner equation describes conservation of mass between sediment in the bed of a channel and sediment that is being transported. [1] It states that bed elevation increases (the bed aggrades) proportionally to the amount of sediment that drops out of transport, and conversely decreases (the bed degrades) proportionally to the amount of sediment that becomes entrained by the flow.

CBM – coal-bed methane; CCHT – core chart log; CCL – casing collar locator (in perforation or completion operations, the tool provides depths by correlation of the casing string's magnetic anomaly with known casing features) CCLBD – construction / commissioning logic block diagram; CCLP – casing collar locator perforation
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid.
Roseburg's elevation is approximately 500 feet (150 m). Its highest point is Mount Nebo, a 1,200-foot (370 m) hill to the west of Interstate 5. Through the 1980s, it was known for its band of 10-20 feral angora goats. Residents said they could predict the weather by watching where the goats were on the mountain; if they were high, the weather ...

A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
