Watersheds are affected by different physical and climatic differences.
Climates refer to the weather in a region over a long period of time.
Your location will determine the type of the seasonal input of water.
Temperature of the atmosphere caused by solar radiation will also
control the rate and nature of the precipitation.
Physical make-up of the area where water flows will also make a
difference. If the rocks and soil are "soft," water can erode
it easily. The steeper the topography the greater the runoff and
erosion. An earthquake can cause an uplift in an area that can change
the shape and extend of how the water flows. Humans can create a dam or
build a large structure which change the course of a river, which effect
an entire area.
