Runoff

  • All downhill flow is called runoff

  • What factors influence runoff?

    • 1.

    • 2.

    • 3.


What factors influence runoff
What factors influence runoff? Broad River watershed

  • The presence of impervious surfaces

    (roads, parking lots)

    2. Soil type

    (hard-packed clay forms runoff)

    3. Steepness of slope

    (runoff is faster and more pronounced on

    steep slopes)

Three ways materials can be carried in rivers
Three ways materials can be carried in rivers: Broad River watershed

  • In solution (particles are completely dissolved)

  • In suspension (particles are small enough to be swept along in the current)

  • In bed load (sand, pebbles, small rocks are dragged along the bottom of fast-moving streams)

At a river’s supply a streambase level (its lowest point), it empties into another body of water.This location is called the mouth of the river.


Major rivers form deltas at their mouths
