ConvertDischarge: Calculate Specific runoff from volumetric discharge and vice versa

Description

ConvertDischarge converts volumetric discharge to specific discharge (unit area discharge) and vice versa.

Usage

ConvertDischarge(q, area, from = "m3s", to = "mmd")

Value

ConvertDischarge returns a numeric object of the same type as provided in argument q.

Arguments

q

An object of type numeric, containing volumetric or specific discharge values, typically HYPE variables COUT or ROUT.

area

An object of type numeric, containing a catchment area in \(m^2\).

from

Character string keyword, giving the current unit of q. Either a specific discharge, one of:

"mmy" (\(mm y^{-1}\))

"mmd" (\(mm d^{-1}\))

"mmh" (\(mm h^{-1}\)),

or a volumetric discharge, one of:

"m3s" (\(m^3 s^{-1}\))

"ls" (\(l s^{-1}\)).

to

Character string keyword, see from. Conversion will not work between units within volumetric or specific discharge groups.

Details

ConvertDischarge is a simple conversion function, most likely to be used in combination with apply or related functions.

Examples

ConvertDischarge(6, 400000000)
ConvertDischarge(c(1.1, 1.2, 1.9, 2.8, 2, 1.5, 1.3, 1.2, 1.15, 1.1), 
                 from = "mmd", to = "ls", area = 1.2e6)
