The challenges facing water managers and engineers nowadays are manifold, complex, and require cross disciplinary approaches. These challenges include the safety of hydraulic natural and built systems, ageing infrastructures, pollution, guarantee of energy and food security, sustainable development and safety of urban environment, ecological feedbacks and an uncertain future.
Our group develops research towards engineering solutions for the design, the planning and the implementation of sustainable water infrastructures prepared for global change. We investigate the mechanics of flowing water and its interaction with key elements of a river basin such as sediments, dissolved matter, gases, living organisms and people. More specifically, the group is committed to develop research on four main topics: sustainable and secure water for supply, food and energy; adaptive and multi-functional hydraulic systems; healthy rivers; and geophysical processes in rivers and lakes.
Physically-based hydrological models can be understood as an upscaling exercise of hydrodynamic numerical models.
The latter have experienced great development in the past two decades, which together with the accelerated growth of computational power, now enable to tackle catchment and even regional scale hydrological modelling based on such tools.

On July 23, 2024, we gathered for our annual summer excursion. We embarked on a delightful bike ride through the Oberwald, eventually arriving at Wasserwerk Oberwald, the historic water distribution plant of Karlsruhe.
After an enlightening tour and our customary group photo, we continued our journey to the Städtsche Galerie. There, we immersed ourselves in the captivating art exposition, Hydromedia, where international artists showcased experimental artistic methods to raise awareness about water usage, management, and its ecological value.
Returning to the lab, we concluded this intense and fulfilling day with a relaxing barbecue. We are already looking forward to our next excursion!
We were lucky with the weather on yesterday's student excursion to 2 small hydroelectric power plants as part of the lecture on hydropower engineering. The "Sägemühle" at the river Enz (2 Francis turbines, 1 hydroelectric screw) was extensively modernized and expanded a few years ago by the owner (Mr. Dieter Heilig). Besides the increase of efficiency resp. output, the focus was on improving the ecological conditions.
Just before the onward journey to the Upper Neckar, heavy rainfall began, but was replaced by glorious sunshine just in time for our arrival. At the Horb-Mühlen plant (1 Kaplan tube turbine, 1 hydroelectric screw), Mr. Frank Bürkle (E-Werk Stengle) answered questions regarding hydraulic and technical aspects, including the implemented horizontal rake (fish protection) and also gave insights into electricity marketing, network operation and control technology.
Restoring continuity and connectivity along rivers is essential for river ecosystems and biodiversity.
The speaker will take you on a short journey along a river from its source to its mouth and demonstrate the relevance of various research projects and involved numerical modelling using a number of recent examples.

The 10th International Symposium on Environmental Hydraulics 2024 was organized by the University of Aberdeen, Scotland, 25 – 26 June.
Mario Franca presented orally the paper “On the turbulence nature of vegetated compound channels”, with Luiz Oliveira as first author, and co-authored by Johannes Janzen, Frederik Folke, Florian Wittmann, Nils P. Huber and Carlo Gualtieri. In this, results from the project “The hydraulics of four moments in the life of a floodplain forest” were presented, a collaboration between IWU-KIT, the University of Naples Federico II, in Naples, Italy, the Institute of Floodplain Ecology from KIT, the Federal University of Mato Grosso do Sul, in Campo Grande, Brazil, and the Federal Waterways Engineering and Research Institute (BAW), Germany. On the day before the conference, Mario Franca and Olivier Eiff from IWU invited to participate in a workshop on Very Large Scale Motions in open-channel flows.

From June 17th to June 19th, the 10th IAHR International Symposium on Hydraulic Structures took place in Zürich.
Hydraulic structures are and will be a vital part of the infrastructure for human beings as they provide safe irrigation and water supply, protection against natural hazards, energy generation, and many other highly needed services. Given the current global challenges including water scarcity, abundance in the form of floods, need for clean and affordable energy and environmental issues related to watercourses as biodiversity hotspots, hydraulic structures will remain very relevant in the future.
This was demonstrated by more than 180 Participants from all continents taking part, Frank Seidel represented the IWU-WB.
