Runoff coefficient definition

Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff.

Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff. Runoff coefficient is also defined as the ratio of the amount of water that is not absorbed by the surface to the total amount of water that falls during a rainstorm.

Runoff coefficient means the frac- tion of total rainfall that will appear at a conveyance as runoff.

Examples of Runoff coefficient in a sentence

More Definitions of Runoff coefficient

Runoff coefficient means a term used to describe the percentage of precipitation that leaves a particular site as runoff. Runoff is precipitation that does not soak or absorb into the soil surface and is greatly impacted by the amount of impervious surface that exists on a particular site. The runoff coefficient relates the amount of impervious surface to the intensity of development.

Runoff coefficient means the fraction of total precipi- tation that will leave a project site or selected site as runoff based on land use, soil and drainage characteristics.

Runoff coefficient means the percentage of precipitation that appears as runoff. The value of the coefficient is determined on the basis of climatic conditions and physiographic characteristics of the drainage area and is expressed as a constant between zero and one.

Runoff coefficient means thefraction of total rainfall that will appear at the conveyance as runoff.

Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff. “Semi-Arid Areas” means areas with an average annual rainfall of 10 to 20 inches.

Runoff coefficient means the average annual fraction of total precipitation that is not infiltrated into or otherwise retained by the soil, concrete, asphalt or other surface upon which it falls that will appear at the conveyance as runoff.

Runoff coefficient means the fraction of total rainfall that will appear at a
