The river Liesing is located in the South of Vienna. It has two souces, the “Dürre Liesing” and the “Reiche Liesing”. While the Dürre Liesing arises from a limestone area, the Reiche Liesing arisies from the flysch limbestone area of the Wienerwald, which makes the river grow rapidly in case of heavy rainfall, this lead despite the strict regulation in a concrete river bed to the river bursting its banks. In Vienna river Lising has shaped the landscape through meanders, deposition of sediments and erosion earlier, but after a havy regulation in the 50ies followed by an even stricter regulation in the 70ies it was forced in the staight river bed, which lead to a low biodiversity and to the river running quickly. After housing development in the areas around the river, mainly in the 90ies, first attempts to rearrange the surrounding and to adapt it to the new user needs were atarted, after two major fluds in the 90ies, and the implementation of the European Water Directive the City of Vienna decided for the revitalisation of a 5,5 km area of the river to be completely renewed and revitalised.
