Calculate the Curve Number from time series data (P and Q)
EmpiricalCN(tseries, stepsBack = 5, hours2extend = 6, timeUnits = "hours",
verbose = FALSE)
Arguments
- tseries
- time series object containing, at least, precipitation ("P") and discharge ("Q")
- stepsBack
- timesteps to use to generate the linear model for the volume under the rising limb (default = 5)
- hours2extend
- number of hours to extend the rainfall event to account for the discharge peak to occur (default = 6)
- timeUnits
- time step units (default = "hours")
- verbose
- (optional) boolean (FALSE by default). If TRUE prints the progress in terms of event number.
Value
Empirical Curve Number for a given catchment, this is an integer in the range [0,100] with 0 = no runoff and 100 = all rainfall becomes runoff.
Examples
## Not run: ------------------------------------
# data("SevernTS")
# severnCN <- EmpiricalCN(tseries = SevernTS)
