Pre-set Event Hydrographs

event_hydrographs.Rd

Constructs event hydrographs with characteristic shapes:

Usage

hyd_snow(peak, baseflow, duration = 9 * 24)

hyd_rain(peak, baseflow, duration = 3 * 24)

hyd_const(peak, duration = 1)

Arguments

peak, baseflow

Peak and baseflow discharges; single numerics.

duration

Length of the event. Defaults to 3 days for rainfall-related events, and 9 days for snowmelt-related events (in hours).

Details

  • hyd_rain() is characteristic of a rainfall-related event.

  • hyd_snow() is characteristic of a snowmelt-related event.

  • hyd_const() is a flat hydrograph.

Rainfall-related event hydrographs are triangular, rising from baseflow to peak in 1/3 the duration, followed by a recession to baseflow.

Snowmelt-related event hydrographs are like the rainfall hydrographs, but remain at the peak discharge until half of the event duration.
