Runoff
Contributed by Mr. Scanga
Doesn’t soak into the ground or evaporate; runs over surface of earth.
• Amount of rain• Length of time rain
falls• Slope of land• Vegetation
Factors affecting amount of runoff
• Steeper slope, more runoff• More gentle slope,
less runoff• Has to do with
speed of the water
Less vegetation, more runoff
• What I chose to study:– How water flows over different slopes– Observe the difference– Observe runoff
Steeper Slope Less Steep Slope
Less runoff, less erosion
