QMEDLink: 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 desciptor; 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.
