To the big Weir at the Weser river and huge barges lock
- Written by Portal Editor
Once again being guests in Bremen we went out for a long walk along the Weser due to late autumn sunny weather, this time we first took the tram to the Weser Weir and the great Weser lock on Hastedter Osterdeich.
From here we started along the Weser Weir used the pedestrian bridge, then along the large Weser lock turned over to the beautiful Werdersee with its beach and then back to the city center.
Bremen's flood protection by the Weser Weir
A large operating bridge is crossing the Weser weir, which can also be used by pedestrians and cyclists and many other users enjoy it too, including us during our walk. The bridge is located about five meters above the upper water, which also gives a great panoramic view of the lock system. It connects the operating bridge and the locks, so that cyclists and pedestrians can cross the entire barrage and overlook.
Flood regulation for the Weser but also for the North Sea
The weir is dimensioned for an outflow of 3,400 m³ / s. Because of the seize, the new weir can drain more water than it was the case with the old weir. Overall, the flood discharge concept at the Bremen barrage provides for a discharge of 4,200 m³ / s. The difference between the total discharge and the outflow by the weir is dissipated via a side drainage area by the Werdersee and the Kleine Weser. However, during the flood in March 1981, it became apparent that the lateral drainage area was no longer able to absorb the planned volume of water due to increasing build-up. The water jammed into the side room intended for the drain and finally broke through the dike below the barrage and lock system, which was subsequently re-regulated the flood discharge.
Next to the Weser weir there is a fish ladder on the island between the weir and the lock. Another fish passage was created in connection with the Weser power plant on the right bank of the river.
Large lock for the navigation at the Weser Weir
The upper gate of the lock consists of a part wise turning gate. To protect the gates, there is a safety net at the upper gate inside the lock chamber. The gate can be protected by a rope from the upper water. A corresponding shock protection in the form of a rope is also located in front of the gate below.
At the Weser flood of March 1981, the planned torrent did not prove itself. The masses of water pouring in from the Mittelweser searched for another route, already streaming into the lower Weser at Karl-Carstens-Brücke and digging a deep new bed.
Werdersee and Kleine Weser - use at high tide
Through complex measures in the renaturation of the small Weser and Werdersee thus also a recreational area with beautiful trees, biking and hiking trails for the city dwellers was introduced. Even a beach could be created, which is heavily frequented in the summer. We were accompanied by the gloriously colorful leaves of autumn and winter.
