Buffer strips of native grasses, plants, or turf reduce nitrogen and phosphorous in runoff water. Buffer areas receiving infrequent irrigation and fertilization provide a filter for nutrients from surface runoff water. The dense vegetation of a buffer slows runoff and allows time for water to infiltrate into the soil.

What is runoff in geography?

The sum of all the water flowing over the drainage basin’s surface is called runoff. It is made up of streamflow, which is flow through permanent river channels, and overland flow or surface runoff.

How does vegetation affect runoff?

Trees and other vegetation in urban areas considerably reduce urban-water runoff. As rain falls upon vegetation, it clings to the rough surfaces of leaves, branches, and trunks. … By intercepting and slowing precipitation hitting the ground, vegetation substantially reduces the volume and rate of stormwater runoff.

What is runoff process?

(Entry 1 of 2) 1 : a final race, contest, or election to decide an earlier one that has not resulted in a decision in favor of any one competitor. 2 : the portion of precipitation on land that ultimately reaches streams often with dissolved or suspended material.

What is called runoff?

Runoff is nothing more than water “running off” the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.

Change in Land Cover and Land Use (LCLU) influences the runoff characteristics of a drainage basin to a large extent, which in turn, affects the surface and groundwater availability of the area, and hence leads to further change in LCLU. This forms a vicious circle.

What does fertilizer runoff cause?

Too much fertilizer can actually kill the plant and excess fertilizer can runoff into streams and lakes causing toxic algal blooms that are harmful to aquatic life and even people and their pets. Excess fertilizer runoff from lawns and agricultural applications also contribute to aquatic “dead zones” in coastal areas.
