Töging am Inn hydropower plant

Habitat and scouring studies in the diversion section of the Töging am Inn hydropower plant

Context

VERBUND-Innkraftwerke GmbH plans to increase the efficiency of the power plant Töging at the River Inn, Bavaria. An interdisciplinary hydromorphological and ecological study is conducted to minimize the impact on the approx. 30 km long residual flow reach. Therefore, the hydraulic laboratory of the University of Applied Sciences Karlsruhe (VAW) investigates the clogging of the riverbed and its impacts on riverine habitat for fish on behalf of the Institute for Modelling Hydraulic and Environmental Systems (IWS) of the University of Stuttgart to investigate the effects of river morphological measures on sediment characteristics and river ecology.

Objective

The overall objective of this project is the holistic view on the hydromorphological and ecological situation in the residual flow reach, including the identification of measures and opportunities to fulfil the ecological requirements according to the EU Water Framework Directive 2000 ("good ecological status"). The specific project tasks of the VAW focus on habitat and colmation studies in the residual flow reach.

Methods

The project team investigates the present status and the efficiency of river morphological measures using an innovative monitoring concept for clogging processes. This includes the measurement of hydraulic conductivities, particle size analyses, porosities and the content of dissolved oxygen in the riverbed. Furthermore, the project team simulates the effects of hydromorphological changes on the habitats of native fish species using the habitat suitability model CASiMiR.

Status

Completed project 02/2019 — 07/2021
