streamdefplot: Streamflow Deficit Plot

Description

Gives a plot for a given hydrological year that shows deficit duration, occurrence and volume.

Usage

streamdefplot(lfobj, year, threslevel = 70, thresbreaks = c("fixed",
                 "monthly", "daily", "seasonal"), breakdays =
                 c("01/06", "01/10"))

Value

No return value, called for side effects (plotting).

Arguments

lfobj

An object of class 'lfobj'

year

The hydrological year that should be plotted

threslevel

The threshold level, 70 means that Q70 should be used as threshold

thresbreaks

The periods for which separated thresholds should be used, 'fixed' uses a constant threshold, 'monthly' uses monthly breaks, 'daily' takes daily threshold levels. If 'seasonal' is specified, you can enter the break days manually using 'breakdays'.

breakdays

A vector of break days if thresbreaks = 'seasonal'. Please enter the break days using the format '%d/%m', e.g. c('01/03', '01/09') uses the first of March an the first of September as break days.
