In UKFE: UK Flood Estimation
QMEDLink R Documentation
QMED Linking equation
Description
Estimates the median annual maximum flow (QMED) from non-flood flows
Usage
QMEDLink(Q5dmf, Q10dmf, DPSBAR, BFI)
Arguments
Q5dmf
numeric. The daily mean flow that is exceeded 5 percent of the time
Q10dmf
numeric. The daily mean flow that is exceeded 10 percent of the time
DPSBAR
a catchment descriptor. The average drainage path slope of the catchment
BFI
the baseflow index of the gauged flow
Details
The QMED Linking equation estimates QMED as a function of the flow that is exceeded five percent of the time, the flow that is exceeded 10 percent of the time, the baseflow index, and the catchment descriptor drainage path slope (DPSBAR). All of these can be found for sites on the National River Flow Archive (NRFA) website. The method is provided in the guidance note 'WINFAP 4 QMED Linking equation' (2016) by Wallingford HydroSolutions.
