lp3events function

Find 2- and 10-year return levels

Uses the method of moments to find the 2- and 10-year droughts and floods under the Log-III Pearson distribution.

lp3Events(x)

Arguments

• x: Object of class "streamflow".

Returns

A list with items - Q2: 2-year high return level.

• Q10: 10-year high return level.

• L2: 2-year low return level.

• L10: 10-year low return level.

Details

Return levels are calculated using the method of moments through the package "lmom". High return levels (floods) are calculated using annual maxima of the raw (log normalized) data, while the low return levels (droughts) are calculated using annual mimima of the 7-day moving averages.

Examples

data(sycamore)
syc.sf<-asStreamflow(sycamore)
