A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill.There are no official definitions for the generic term river as ...
There are three types of river regime:-1. Ephemeral Rivers. 2. Intermittent Rivers. 3. Perennial Rivers. 1. Ephemeral Rivers: Ephemeral rivers are characterized by the temporary quick flow as a result of exceptionally heavy downpours or rapid melting of snow.
The Nile River delta is one of several types of deltas that are defined by the predominate processes that shape them. The Nile delta is a wave-dominated delta. Waves of the Mediterranean Sea have pushed and distributed sediment along the coast, flattening the seaward side of delta. The Mississippi River delta is an example of a stream dominated ...
Rivers can run for many hundreds of miles. The longest river in the world is the Nile in Africa. It is 6,700km long. The longest river in Britain is the River Severn, which is 354km long.

The four types, or processes, by which a river erodes are hydraulic action, abrasion or corrasion, attrition and corrosion. Each process affects the river in different ways. Hydraulic action is where the force of the river water pushes into holes in the riverbank and causes the riverbank to collapse.
A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
No matter what their size and shape, all rivers are moving water from one place to another! There are many different types of rivers. Some snake back and forth. Others are straight. Some flow fast. Others flow slowly. The longest river in the world is the Nile in Africa, which flows north into the Mediterranean Sea.
Introduction to River Types. Classifying a cold, flowing body of water according to its geology, chemistry, and the biological life forms that live within it is often difficult, due in large part to the fact that there are so many kinds of moving waters.

Rivers can be short or long, wide or narrow, fast or slow. There are 165 ‘major’ rivers in the world, and literally tens of thousands of smaller ones. The longest river in the world is the Nile River in the Middle East at just over 4,100 miles, while the shortest is the Roe River in central Montana at just over 200 feet.
