Full Answer

In most cases, rivers will have a main source, such as snow melt from a mountain that flows down into multiple streams that then join together to form a river that runs into a much larger river. This is an example of a river system. From an environmental standpoint, river systems are ecosystems that can suffer negative effects on things such as water quality and plant and animal life health if just one part of the system is polluted or damaged. For example, if a river's source suffers from a high level of pollution or a severe drought, the effect will be felt throughout the waterways and lands included in the river system.
