In a peak storm day the amount of precipitation occurred was 21 cm for a 3 hours continuously and the rate of percolation was 60 mm. The surface runoff is 15 cm. Now the question arises what is a surface runoff? When rainfall or snowfall occurrs in a area, the water moves from one place to another place. Runoff is extremely important in that not only does it keep rivers and lakes full of water, it also changes the landscape by the action of erosion because it helps in the erotion. It is how the grand canyon is formed.
