[[Tidal Characteristic Numbers of Salinity|graphical representations of the characteristic numbers of salinity]]
 
 
 
==Motivation==
 
The calculation as well as the graphic visualization of various tidal characteristic numbers of temperature and also for the advective transport of heat contributes to an improved understanding of tidally dominated transport processes in estuaries. Spatial variations of temperature, advective transport of heat by means of flood and ebb currents can be highlighted for areas like coastal seas and estuaries as well.
 
 
 
* As the calculations are performed separately for the durations of ebb- and flood-current it can be shown that transport paths can differ significantly for the two tidal phases. From this one can get additional insight with respect to the relevant transport mechanisms dominated by the tidal currents. This can be related to locally varying flood-ebb asymmetries for ebb volume and flood volume. Also the presence of horizontal gradients can contribute to this effect.
 
 
 
* The variation of temperature resulting from the local maximum as well as the local minimum of temperature can be quite large. This is a consequence of the different temperature of e.g. sea and fresh water. The value for the local temperature variation is mainly the result of the product between the horizontal temperature gradient and the lagrangian drift of a water particle during a complete tidal cycle.
 
 
 
An automatic analysis of all tidal characteristic numbers of temperature is carried through by the computer programs [[TDKSF]] and [[NCANALYSE]].
