StormEvents: Number of Storm Events in a Hydrograph

In NCAR/RNWMStat: National Water Model Performance Evaluations Statistics

Description

Estimates number of storm events based on quickflow time series.

Usage

StormEvents(quickflow,qlimit=0)

Arguments

quickflow	Quickflow time series
qlimit	Minimum quickflow threshold. The StormEvents() function only consider events higher than this threshold while counting events

Value

Retun a dataframe with quickflow and corresponding storm event number.

Examples

data("USGS_Streamflow")

#Baseflow estimate
df<-BaseFlowSeperation(streamflow, bf_method='Duncan', k=0.93, c=quantile(streamflow,probs = 0.25, na.rm=T), filter_parameter=0.925, passes=1)

#Storm Events
nev<-StormEvents(df$qft,qlimit = 2)

#Plot
plot(nev$quickflow,type = 'l')
lines(nev$nEvents,col='red')
