Explanations

Ratio of mean salinity of flood current to mean salinity during the complete tide.

left top: value of characteristic number for a single event.
left bottom: mean value of the characteristic number within the period of data analysis.
right top: maximum value of the characteristic number within the period of data analysis.
right bottom: minimum value of the characteristic number within the period of data analysis.

Examples

mean salinity flood current : mean salinity	mean salinity flood current : mean salinity (maximum)
ratio of mean salinity flood current : mean salinity of one specific tide	maximum value of ratio of mean salinity flood current : mean salinity within the period of data analysis

mean salinity flood current : mean salinity (mean)	mean salinity flood current : mean salinity (minimum)
mean value of ratio of mean salinity flood current : mean salinity within the period of data analysis	minimum value of ratio of mean salinity flood current : mean salinity within the period of data analysis
