The present course of the Wiese on Swiss territory was already planned in the early 19th century by construction inspector Baader. Interesting is its absolutely straight course between the bridge over the Wiese at Weil and the Iron Bridge. It is parallel to the visual axis of Stetten Church and Basel Minster. The original embankment was a platform system ("Bühnensystem"), but in the 1850s it was replaced by a threshold system ("Schwellungssystem") after the serious flood of 1852. For the river bed, a double trapezoid profile was envisaged, with a summer bed and the flood water embankments. The banks were still largely reinforced with fascines, wattle and grass. Between 1847 and 1878 there were 13 severe floods, all of which led to damage and destruction of the riverbank defences. Only after the great Christmas flood of 1882 was a uniform defensive system built on the Swiss Wiese.
