Most people believe that bears are too large and too heavy to run down the hill. However, the truth is that a bear can run up, down, and along a hill.
If rainwater runs downhill down a street to get to the river and the river is flooding, the water will run back uphill (i.e. it will back-up) because it has no other place to go.

Obviously, a body of water the size of a stream or river will succumb to the immutable forces of gravitational attraction, inertia, and the other laws of physics, and be forced to flow downhill. There are some rivers that run from south to north (which is opposite of most), and some that seem to run "backwards", but no rivers run uphill. The starting point of all rivers and streams is of a higher elevation than their end point.
confluence, where two or more rivers or streams merge into one. This creates a larger body of water and is an important geographic feature in many landscapes.
It really depends on where the stream is located but often streams accumulate the majority of their water from run off and rain water. However some streams are fed from larger bodies of water as well.
Where water that has fallen from the clouds goes down the surface of a hill/mountain and goes into a river
