Description of solution
The originally natural gradient of the Iller is largely removed by the transverse structures erected as a result of the straightening of the Iller. This created waterways with a low gradient and the pre-alpine watercourse characteristics were lost. Through the construction of side arms, an attempt is being made to create an extended watercourse habitat with natural bed layers and high habitat function. It enables an approximation to the natural, branched course of the watercourse with its numerous side channels. The measure is part of the project Agile Iller.
