Salzach - Natural river concept in the Freilassing Basin


Salzburg State Government


Austria | Salzburg


from May 2015 to December 2015


General project, Hydraulic modelling (2D), Design of flood protection measures, Design of river renaturation measures

  • Hydraulic engineering/river engineering
  • Morphology and water protection

Project objectives

This project aims to implement the concept of a nature park "Naturpark Salzachauen", as presented by the "Haus der Natur - Nature Museum".

Project description

Within the framework of maximum space availability, a significantly larger development space is aimed for in contrast to earlier concepts. The aim of the project is the restoration of a water body condition that conforms to the overall concept

Project data

Project length: app. 4 km
Project area: app. 50 ha
MQ = 240 m³/s
HQ100 = 3100 m³/s

Project specifics

The project planning was an interdisciplinary process of hydraulic engineering / morphology and ecology. As a natural flow concept, hydraulic engineering and morphology on the one hand focuses on spatial development and river bed stability, while at the same time planning must take account of use/interests/rights and compensation of hazards.
