In Tides: Tides

Description Usage Arguments Value Author(s) See Also Examples

Calculates the characteristics of observed tidal water levels. Wrapper of the functions `extrema`

, `IT`

and `IF`

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

`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 |

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 |
