,RIVERS have always been important to humans, and many of the world’s ancient and greatest civilisations were established near rivers. Even today, the capitals of several countries are situated on riverbanks.
Rivers benefit communities in ways that are easily recognisable: they are a source of water for domestic, agricultural and industrial purposes and of food and livelihoods; they can be used for transportation; those that are amenable to damming are used to supply energy needs; and they are often used for recreational and religious activities. Rivers also serve less obvious functions that are as important as the obvious ones. They are feeding and spawning areas for fish and other aquatic biota and can purify water as they have the ability to break down or absorb pollutants. A properly maintained river system can act as a drainage area and help in flood management. Because the water table is at or close to the surface in river basins and because sand retains water, rivers perform the important functions of water storage and groundwater replenishment. The last two functions are applicable to dry rivers as well as those with perennial flows.

Hey here your answer...
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 applied to geographic features,although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek,but not always: the language is vague.
