Corrective measures on the Wiese were hampered in past centuries by various natural circumstances and by human and/or administrative shortcomings. The seasonal floods that occurred and the large amount of debris were always detrimental to the riverbank defences and height of the riverbed and thus on the capacity of the river bed. The corrective measures carried out in the Baden part of the Wiese resulted in an increased discharge of the floodwater into the Swiss area and thus imposed a greater load on the local flood defences. The lack of willingness on the part of individual river owners to cover the costs of necessary maintenance work prevented the long-term correction of longer river sections.
