The Horseshoe Falls, one of the three Niagara Falls.The falls are a knickpoint, formed by slower erosion above the falls than below. In geomorphology, a knickpoint or nickpoint is part of a river or channel where there is a sharp change in channel bed slope, such as a waterfall or lake.
Horseshoe-shaped falls focus the erosion to a central point, also enhancing riverbed change below a waterfall. [15] A process known as "potholing" involves local erosion of a potentially deep hole in bedrock due to turbulent whirlpools spinning stones around on the bed, drilling it out.
A plunge pool (or plunge basin or waterfall lake) is a deep depression in a stream bed at the base of a waterfall or shut-in. It is created by the erosional forces of cascading water on the rocks at the formation's base where the water impacts. [ 1 ]
Although somewhat related to a pothole in origin, a plunge pool (or plunge basin or waterfall lake) is the deep depression in a stream bed at the base of a waterfall. It is created by the erosional forces of turbulence generated by water falling on rocks at a waterfall's base where the water impacts. [ 2 ]
Capote Falls is a waterfall on Capote Creek in the Sierra Vieja mountains in northwestern Presidio County, Texas, United States. At up to 175 feet (53 m) tall, it is the highest waterfall in Texas. At up to 175 feet (53 m) tall, it is the highest waterfall in Texas.
Hydraulic action, most generally, is the ability of moving water (flowing or waves) to dislodge and transport rock particles.This includes a number of specific erosional processes, including abrasion, at facilitated erosion, such as static erosion where water leaches salts and floats off organic material from unconsolidated sediments, and from chemical erosion more often called chemical ...
Lake bed downcutting is the erosion of cohesive material such as clay or glacial till from a shoreline by wave action. When the sand cover is stripped away and the cohesive layer is exposed, cohesive material is lost to the water column. Unlike sand, cohesive material cannot be replenished by natural events such as bluff erosion. This can ...
River rejuvenation can lead to a number of changes in landscape. These include the formation of waterfalls and rapids, knick points, river terraces and incised meanders. [1] Rejuvenated terrains usually have complex landscapes because remnants of older landforms are locally preserved.
