EasyGSH-DB: Tide characteristics of the flow velocity (TDKv)

Motivation: Like the tide characteristic values of the water level, the calculation and graphical representation of different tidal characteristics of the flow contribute to the development of selected aspects of tidal dynamics separately for the ebb and flood current as well as for the entire tides in coastal waters and estuaries. In particular, the calculation of the tidal characteristic values of the flow, carried out separately for the flood current and the ebb current, provides an insight into the inequality or asymmetry of the tide phases. This inequality can be expressed, for example, in different lengths of flood and low tide current durations. Also, the maximum flux and ebb current velocities achieved as a result of different long tidal phases or as a result of the varying rapid rise or fall of the water level (this results in different accelerations) may differ more or less from each other. Differences in the max. flow velocities can be one of the main causes of residual ebbe- or flood-oriented sediment transport. A detailed description of the analysis modes can be found in BAWiki (http://wiki.baw.de/de/index.php/Tidekennwerte_der_Strömung).
