A meander is a bend in a river found in older rivers when the water moves slowly. A flood plain is the area of ground beside a river which is submerged in a flood. The estuary is where a river enters the sea.
A tributary does not flow directly into a sea. Tributaries and the mainstem river serve to drain the surrounding drainage basin of its surface water and groundwater by leading the water out into an ocean or some other large body of water. A confluence is where two or more bodies of water meet together, usually referring to the action of tributaries. An affluent is synonymous to the word 'tributary', being defined as a stream or river that simply flows into a larger one.
A parallel to tributaries is the distributary, a river that branches off of and flows away from the main stream. SOURCE The source or headwaters of a river or stream is the place from which the water in the river or stream originates.
There is no universally agreed upon definition such that any stream's source can be systematically determined. The United States Geological Survey USGS states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source irrespective of stream name or from the mouth to the headwaters of the stream commonly identified as the source stream".
By another definition a source can be defined specifically as the most distant point from the river mouth in the drainage basin from which water runs year-around perennially, or, alternatively, as the furthest point from which water could possibly flow ephemerally.
As the river wanders between banks that are far apart, the promontories of the hills tend to jut out into the river valley in a staggered formation, interlocked together in a formation like the teeth of a zip. These promontories are referred to as interlocking spurs. While similar in general appearance, the mechanism behind the formation of interlocking spurs is different to that behind meandering and they should not be confused.
If the valley experiences glaciation, the interlocking spurs are foreshortened as the tips are sheared off. These are referred to as truncated spurs. How interlocking spurs are formed: Vertical erosion creates a narrow valley. They line up one after the other. A meander is formed when the moving water in a river erodes the outer banks and widens its valley. A stream of any volume may assume a meandering course, alternatively eroding sediments from the outside of a bend and depositing them on the inside.
The result is a snaking pattern as the stream meanders back and forth across its down-valley axis. When a meander gets cut off from the main stream, an oxbow lake is formed. Over time meanders migrate downstream, sometimes in such a short time as to create civil engineering problems for local municipalities attempting to maintain stable roads and bridges.
Insects, mammals and birds use the delta for their homes and for food. River valleys and plains provide fertile soils. Farmers in dry regions irrigate their cropland using water carried by irrigation ditches from nearby rivers. Rivers are an important energy source.
During the early industrial era, mills, shops, and factories were built near fast-flowing rivers where water could be used to power machines. Today steep rivers are still used to power hydroelectric plants and their water turbines.
Farming River valleys and plains provide fertile soils.
Rivers drain nearly 75% of the earth's land surface. Habitats. Rivers provide excellent habitat and food for many of the earth's organisms. Many rare plants and trees grow by rivers. Ducks, voles, otters and beavers make their homes on the river banks. Reeds and other plants like bulrushes grow along the river banks.
What is a river? A river is the path that water takes as it flows downhill towards the ocean. Rivers can be long or short, wide or narrow and they often join together on their way .
