# 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

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

• In the Rational Method, the peak rate of runoff, Q, in cubic feet per second (cfs) is computed as: Q = CIA Where: C = Runoff coefficient, representing the characteristics of the drainage area and defined as the ratio of runoff to rainfall.

• Size in acres, Runoff coefficient (C), and Time of Concentration (Tc) for each drainage area based on pre- and post-development conditions.

• In the Rational Method, the peak rate of runoff, Q, in cubic feet per second (cfs) is computed as: Q  CIA Where: C = Runoff coefficient, representing the characteristics of the drainage area and defined as the ratio of runoff to rainfall.

• Runoff coefficient, dependent on land use/cover I = Design rainfall intensity, inches per hourA = Drainage Area, acres.C. All calculations consistent with this ordinance using the Soil Cover Complex Method shall use the appropriate design rainfall depths for the various return period storms according to the National Oceanic and Atmospheric Administration (NOAA) Atlas 14 rain data corresponding to the Doylestown rain gage, seen in Table B-1 in Ordinance Appendix B.

## More Definitions of Runoff coefficient

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