−  ==Motivation==
 
−  The calculation as well as the graphic visualization of various tidal characteristic numbers of suspended sediment concentration and also for the advective transport of suspended sediment contributes to an improved understanding of tidally dominated transport processes in estuaries. Spatial variations of suspended sediment concentration, advective transport of suspended sediment 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 floodcurrent 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 floodebb asymmetries for ebb volume and flood volume. Also the presence of horizontal gradients can contribute to this effect.
 
−  * The variation of suspended sediment concentration resulting from the local maximum as well as the local minimum of suspended sediment concentration can be quite large. This is a consequence of the different availability of suspended sediments, e. g. inside or outside of the turbidity maximum. The value for the local suspended sediment concentration variation is mainly the result of the product between the horizontal suspended sediment concentration gradient and the lagrangian drift of a water particle during a complete tidal cycle, but also effected by the strong spatial variation of deposition and erosion of suspended sediments throughout the estuary.
 
−   
−  An automatic analysis of all tidal characteristic numbers of suspended sediment transport is carried through by the computer program [[TDKSF]].
