Example: Maximum Rise Velocity in the Ems Estuary
From BAWiki
Maximum Rise Velocity
This figure shows the maximum rise velocity within the period of data analysis in the Ems Estuary calculated for the scenario of a synthetic storm surge.
The maximum rise velocity for the water surface is calculated from the variations of water level within a given time span (typically half an hour) and extrapolated to a one hour period. A general increase can be observed from the North Sea (top left) towards the Dollart bay (bottom right). The velocities vary from approximately 1 m/h to 2 m/h. They are significantly higher compared with the calculated maximum fall velocities.
