In Vorderhindelang, a town district in the Oberallgäu region of southern Germany, a new dam is being built to protect the area from mudslides. Based on knowledge gained from a mountain stream rehabilitation project, the danger of a large mud and debris flow – with an estimated volume of around 10,700 m³ of alluvial deposits and 1,200 m³ of driftwood – in the event of an extreme flooding event became clear. The current protection system on the Dorfbach stream is adequate for a strong flood, but not for the effects of a landslide on the adjacent buildings and their inhabitants.
Inros Lackner, working together with the engineering firm Kokai, was commissioned by the water management authority in Kempten to carry out the planning and design work, and is also responsible for the awarding of contracts and for construction supervision. The project scope includes, among other aspects, the access roads, the consolidation and controlled release dam, modification of the existing dam, scheduling, and construction site logistics. The total cost of the project is around 4.5 million euros. In March 2022, work commenced on the laying of pipework to divert the Dorfbach stream, enabling the construction work to be carried out on dry ground as far as possible.
