The predominant microbial lifestyle in most aquatic ecosystems is the biofilm where microorganisms settle in multispecies communities at solid/water interfaces. While hydrodynamic largely dictates available substratum, initial settlement as well as growth of biofilm, the influence is not unidirectional: further development of these microbial cities shapes strongly their adjacent physical and chemical surrounding. These mutual interactions between flow-biofilm-sediment have important consequences for a variety of biofilm functions to impact the morphology of lotic and lentic waters as well as water quality and ecological health of the aquatic ecosystems (Gerbersdorf & Wieprecht 2015).
The aim of the workshop is to analyze the complex interactions between hydrodynamics, biofilms and sediments by means of future-oriented approaches and methods in order to achieve a better understanding of the processes. Within the framework of the workshop, natural and engineering scientists from research institutions in Baden-Württemberg and beyond will come together to discuss and test the application of new methods for the characterization of interactions with a special focus on sediment stability.
As a kick-off event of the workshop, a public symposium took place at the University of Stuttgart, Institute for Modelling Hydraulic and Environmental Systems (IWS), seminar room 2 (1.002) on 12 June 2018, 9:00 – 14:00:
Hydrodynamics – Prof. Dr. Jochen Aberle (TU Braunschweig)
Biofilms – Dr. Sabine U. Gerbersdorf (University of Stuttgart)
Microsensors – Dr. Dirk de Beer (Max Planck Institut for Marine Microbiology)
