Volume-Based Runoff Coefficients for Urban Catchments

Journal of Irrigation and Drainage Engineering, 2014
AbstractThe rational method is derived as a special case of kinematic wave flow. The definition of runoff coefficient is expanded from the peak-based to volume-based ratio between runoff hydrograph and rainfall hyetograph. The new method presented in this paper provides a dimensionless approach to derive the runoff coefficients for the conventional two-

Roughness Coefficients for Routing Surface Runoff

Journal of Irrigation and Drainage Engineering, 1986
Hydraulic roughness coefficients have been derived from runoff plot data originally collected for erosion studies. The data were collected from different agricultural and natural surfaces by applying constant rainfall rates from rainfall simulators. The derived roughness coefficient is actually an “effective” roughness coefficient that includes: the ...

The runoff coefficient as the key to moisture recycling

Journal of Hydrology, 1996
Moisture recycling by evapotranspiration from vegetation is probably the most important mechanism sustaining rainfall on continental catchments, particularly in semiarid areas. A very simple and very useful parameter to evaluate moisture recycling is the annual runoff coefficient CR.

Synthetic Design Hyetograph and Rational Runoff Coefficient

Journal of the Irrigation and Drainage Division, 1976
A simple method of establishing the synthetic design hyetograph is presented. The method is based on rainfall intensity-duration-frequency curves with simple computation. The method incorporates the rainfall duration, rainfall depth, and the advancing storm patterns.

Relation Between Curve Number and Runoff Coefficient

Journal of the Irrigation and Drainage Division, 1981
The rational method is probably the one most widely used for estimating peak discharges for inlet designs on small watersheds. The basic input requirements include the drainage area, a rainfall intensity for the design return period, and a runoff coefficient (C).

Empirical Determination of Rational Method Runoff Coefficients

Journal of Hydrologic Engineering, 2009
The rational method for determining peak flood discharges has been used for the design of hydraulic structures for decades. Despite the popularity of the method, little attention has been paid to improving guidance for selection of the runoff coefficient.
