Sheet erosion, Pullman, Washington, 1946 Sheet erosion or sheet wash is the even erosion of substrate along a wide area. [1] It occurs in a wide range of settings such as coastal plains, hill slopes, floodplains, beaches, [2] savanna plains [3] and semi-arid plains. [4]
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
The complexities involved in studying sheet flows, including the need for advanced modeling techniques to accurately simulate flow dynamics and sediment transport mechanisms.
Colluvium (also colluvial material or colluvial soil) is a general name for loose, unconsolidated sediments that have been deposited at the base of hillslopes by either rainwash, sheetwash, slow continuous downslope creep, or a variable combination of these processes.
Economic geology – Science concerned with earth materials of economic value; Engineering geology – Application of geology to engineering practice; Environmental geology – Science of the practical application of geology in environmental problems. Geochemistry – Science that applies chemistry to analyze geological systems
A downslope view of part of the eroding rill network from County Tyrone, Northern Ireland.See below for a close-up view of a single rill. In hillslope geomorphology, a rill is a shallow channel (no more than a few inches/centimeters deep) cut into soil by the erosive action of flowing surface water.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms. Depressions form by various mechanisms. Types
