Storm hydrograph base flow
WebTo match the runoff depth given by the SCS runoff equation, the time span must include all times at which runoff will occur. To "see" the entire runoff volume (and the equivalent runoff depth) the time span must end sometime after the end of the storm. For a 24-hour storm, a span of 0-30 hours will generally include all the runoff. http://mrbgeographyib.mrbgeography.com/files/83%20storm%20hydrograph.pdf
