Description

Calculates the characteristics of observed tidal water levels. Wrapper of the functions extrema, IT and IF

Usage

TidalCharacteristics(h,h0 = h$h0,T2 = 5*60*60, hoffset = 3, filtconst = 1, dtMax = 15,unit = "mins", Tavg = 12.4*60 ) 
TC <- TidalCharacteristics(h,...)

Arguments

h

Water level time series. data frame with time and h column

h0

Reference level, either single valued or vector with dimension corresponding to h

T2

'Lower' bound on half the quasi period, but higher than expected stagnant phase; default = 5h

hoffset

Offset level, to prevent spurious maxima generation due to small fluctuations

filtconst

Filtering constant for smoothing the time series

dtMax

Maximum accepted time interval in a continuous series. Bigger time intervals are considered to be gaps

unit

Unit of dtMax, Tavg

Tavg

Average period of time series

Value

An object of class Tides, i.e. a list containing:

HL

Data frame with extrema

h

original water level data frame with additional attributes

gaps

a data frame containing start and end times of gaps in the series

IF

inundation frequency of the reference level

ITs

inundation times at the reference level

DTs

dry times at the reference level

h0

reference level

N

Total number of cycles in time span
