Example figures: Frequency for the exceedance of water level threshold values

From BAWiki

Explanations

Frequency [0.0,1.0] for which the water level exceeds a given threshold within the period of data analysis.

  • left top: result for threshold -1.875 m.
  • right top: result for threshold -0.875 m.
  • left bottom: result for threshold 0.125 m.
  • right bottom: result for threshold 1.125 m.

Please notice that frequency cannot reach a value of 1.0 in temporarily dry areas (e.g. tidal flats).

Examples

water levels above -1.875 m water levels above -0.875 m
relative proportion of water levels above -1.875 m
relative proportion of water levels above -0.875 m
water levels above 0.125 m water levels above 1.125 m
relative proportion of water levels above  0.125 m
relative proportion of water levels above  1.125 m
