The Earth's rivers comprise only about 0.0001% of the Earth's water. Rivers always flow downhill planimetric maps do not include elevation, so they do not reveal the direction in which rivers flow Source: US Geological Survey (USGS), National Atlas Water flows downhill due to gravity, obviously. That is, 80 percent of the fish are located in about 20 percent of the river. One of the unique features of Pittsburgh's landscape is its three rivers.

Rivers and the Water Cycle How does a river Rivers are formed when group of springs and streams known as headwaters (which have their origin in the mountains), flow down to form a large stream or springs. Rivers begin at their source in higher ground such as mountains or hills, where rain water or melting snow collects and forms tiny streams.

As viable rivers shows the ground water table, it is usually rather safe to assume that the ground water under the dry river flows more or less the same direction. A river begins on high ground or in hills or mountains and flows down from the high ground to the lower ground, because of gravity. The continent of Australia is marked by a dry environment. The high point can be a mountain, hill or other elevated area. The water in rivers comes from many different sources.
