Erosion of the river banks altering the course; deposition of gravel, sand and mud in calmer stretches; obstructing of the river mouth with sand-bars forming in the estuary and inshore.
meanders
An example of a land feature formed by river erosion is the oxbow lakes.
If you mean how the river widens, the usually cause is erosion.
In cross-section: A 'U' shaped valley is formed from glacial erosion. A 'V' shaped valley is formed by river erosion.
A bend in the river could cause many main points of erosion. This erosion could be caused by water flowing over it.
The faster the speed of water in a river the more erosion is causes. The slower the water the less amount of erosion it causes.
Water erosion causes geography changes. Overtime, a river can erode land and change the direction of the river altogether.
cause erosion and involveprocesses of "flow"
Erosion is either chemical or mechanical (wind, water, ice etc.) and cause the deterioration or decomposition of rock through either of these two processes. The results of erosion contribute to almost every geographical feature on the face of the earth (with the exception to volcano). Some features include: river valleys, river basins, the seashore, coastal cliffs, messa's and buttes, plains etc.
Name a feature that is formed by underground erosion
A fast-moving river will erode the land faster.
The faster the speed of water in a river the more erosion is causes. The slower the water the less amount of erosion it causes.
Hurricanes can causes significant coastal erosion from waves and storm surge. Heavy rain can cause flooding, which can cause great amounts of erosion around river channels.
