Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [17]

Attrition erosion of the coast in Langeland, Denmark, shows how high impact energy of sediment particles affect ocean-land contact points. The rising of sea levels has led to an increase in coastal erosion. This causes concern to policymakers, coastal researchers, and real estate planners due to erosions effect on flooding. [24]
Kiss the Ground is a 2020 Netflix original documentary film. It focuses on regenerative agriculture; the movie profiles scientists, farmers and environmentalists as they explore the important role healthier soil plays in better human and planetary health.
A mountain road in Ladakh that shows signs of mass wasting and erosion that result in bedrock exposure. Satellite images that show the extreme erosion in the Betsiboka Estuary in Madagascar due to deforestation, which results in rapid denudation and one of the fastest changing coastlines.
Mass wasting is a general term for any process of erosion that is driven by gravity and in which the transported soil and rock is not entrained in a moving medium, such as water, wind, or ice. [2] The presence of water usually aids mass wasting, but the water is not abundant enough to be regarded as a transporting medium.
Beach evolution is a natural process occurring along shorelines where sea, lake or river water erodes the land. Beaches form as sand accumulates over centuries through recurrent processes that erode rocky and sedimentary material into sand deposits.
Map of Cape Cod showing shores undergoing erosion (cliffed sections) in yellow, and shores characterized by marine deposition (barriers) in blue. [1]Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass.
