Session E1: The Fish Migration River

Abstract: The FishMigrationRiver is an innovative fish passage designed to break the Afsluitdijk-barrier for fish migration. The Afsluitdijk is a barrier between the tidal Wadden(/North) Sea and inland waters since it was constructed in 1932. The barrier is almost identical to the Haringvliet and Ganzepoot, but the solution is completely different (see other abstracts). The FishMigrationRiver is a large-scale tidal fish passage and is designed to facilitate all species 24h/day and 365 days/year. After years of preparation the project has entered the phase of realisation. I will present the ecologic constraints of the current situation and the relation with backland Lake IJsselmeer and the Rhine, present the main results of the research-phase (focus on fish-ecology) and explain the design and design-challenges. I hope to inspire the attendants to consider applying this concept to other (inter-)national barriers
