If erosion on the outside meander bends continues to take place, ... Deltas - When a stream enters a standing body of water the sudden decrease in velocity causes deposition of sediment in a deposit called a delta. Deltas build outward from the coast, but only survive if the ocean currents are not strong enough to remove...

Rivers meander (twist and turn, as the river in the diagram) when they are traveling on top of a relatively flat surface. They do this, rather than flow in a straight line, because a straight line is not the most efficient path for water to flow.

The image below divides the meander into areas of deposition and erosion. As water enters the meander it slows on the inside and deposits its load to form point bars. Conversly, as the water enters the meander on the outside it speeds up and erodes the surface to form a cut-bank.

Rivers and streams are the routes through which fresh water travels to the oceans. Rivers can carry large amounts of water. Earth's largest rivers include the Nile in Africa, ... Some rivers meander through wide valleys with large floodplains. Others may flow swiftly through narrow canyons, with little or no floodplain.

The primary need of water to roll in a 3-dimensional vortex causes rivers to meander in a gentle to-and-fro motion. The water naturally swings to one bank of a river, turns, and moves across to the opposite bank, and then swings around again in a dancing rhythm of constant motion.

Please explain why do long rivers ( such as the Nile ) flow along serpentine paths rather than straight? ... ; What causes a river to meander is flat / low gradient terrain. When a stream reaches relatively flat terrain / a plain, it slows up because the ground slope cannot sustain the velocity the stream had at...
