The [[ANIMATION|animation]] demonstrates variation of depth averaged salinity in the inner part of the Außenweser [[Estuary]] for a complete tidal cycle (approx. 12h:25m). The data shown have been generated using the two-dimensional (vertically averaged) numerical [[model]] [[Mathematical Model TRIM-2D|TRIM-2D]].
The situation is governed by fresh water inflow from the Unterweser (bottom right) as well as by advective transport of salinity by means of the [[flood]] and ebb currents. Together both effects contribute to the gradual decrease of salinity from the open sea (top left) towards the Unterweser (bottom right) and to a strong local variation of salinity. The area shown belongs to the brackish water zone of the Weser [[Estuary]]. The position of this zone is strongly dependent on the fresh water inflow rate as well as the influence due to regular variations of the [[Harmonic Analysis of Water Level|tides]].

Further interesting insight into the salt transport regime of the Außenweser [[Estuary]] may be obtained by looking at the calculated [[Tidal Characteristic Numbers of Salinity]].

This [[ANIMATION|animation]] is available in three different formats. The resolution amounts to 800 x 600 points (72 dpi)
