Erosion and sedimentation in agricultural ditches modelled using HEC-RAS the variations of particle-bound phosphorus in the runoff water from modeling
So, water erosion is the detachment and transport of soil material by water. This process could be natural or facilitated by human activity. For example, when humans cut down too many trees and plants, the soil remains bare and loose and hence more easily moved by water. Water erosion wears away the surface of the earth.
Inter-rill Erosion. Inter-rill erosion describes the movement of topsoil by rainfall and its resultant surface flow. 2. Rill Erosion. Rill erosion results from the concentrated flow of water in small streams. These small streams are 3. Gully Erosion.
2020-08-19 https://www.patreon.com/freeschool - Help support more content like this!The landscape around us may look permanent, but it is really changing all the time. Soil erosion by water (aka 'water erosion') is the result of rain detaching and transporting vulnerable soil, either directly by means of rainsplashor indirectly by rill and gully erosion. Rainsplash. A close-up view of a single raindrop as it redistributes soil and water. Rain may move soil directly: this is known as 'rainsplash erosion' (or just Soil erosion by water is a widespread problem throughout Europe. The processes of soil erosion involve detachment of material by two processes, raindrop impact and flow traction; and transported either by saltation through the air or by overland water flow. Erosion by Water.
The paper presents the results of the analysis of the water erosion processes of soil occurring in forestry mountain catchment area in the region of West Sudetes
Water erosion wears away the earth ’s surface. A laboratory erosion apparatus has been used to follow the development of erosion damage in copper and other metals by repeated impacts of water drops at velocities up to 300 m/s. Erosion by water creates a wide range of landforms.

Alluvial Fan. A fan-shaped pile of sediment that forms where a rapidly flowing mountain stream enters a relatively flat valley. As water slows down, it deposits sediment (alluvium) that gradually builds a fan. Sometimes flooding and severe weather can damage a property severely.

2005-06-01 · This review reveals that the decrease in water erosion rates with increasing root mass is also exponential, according to the equation SEP e b RP where SEP is a soil erosion parameter (e.g., interrill or rill erosion rates relative to erosion rates of bare topsoils without roots), RP is a root parameter (e.g., root density or root length density Water erosion. Moving water is the most important natural erosional agent.
In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location. Erosion is distinct from weathering which involves no movement. Water erosion occurs when rain, spring run-off, or floodwater carry soil particles away.

Soil erosion by water is the detachment, transport and deposition of soil particles by flowing water. After intense rainfall and runoff events, it can take the form of concentrated flow. The effects are less conspicuous following regular rainfall events, where small amounts of soil are removed. Soil erosion is a key form of soil degradation.
