Hydroelectric power plant excursionHydroelectric power plant 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.

2024_06_24_IAHR_International_Symposium10th IAHR International Symposium on Hydraulic Structures

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.

Bauwettbewerb 2024Bauwettbewerb 2024

On June 12th, the traditional Bauwettbewerb (building competition) took place in cooperation with the IWU-WB.

In this year's competition, teams of three to six people had to design and build an inlet and outlet structure for a hydrokinetic turbine. The aim was to achieve the highest possible energy yield. The five groups' designs were examined and evaluated under the critical eyes of the audience. The “Wingman” design was able to prevail. The innovation: In this design, “wings” unfolded as a result of the flow and thus directed more water through the turbine. The winners will visit the turbine in the Iffezheim Rhine power plant at the invitation of EnBW.

When disasters strike repeatedly: A multi-year drought followed by a mega-flood in eastern BelgiumWhen disasters strike repeatedly: A multi-year drought followed by a mega-flood in eastern Belgium

In July 2021, parts of Germany, Belgium, the Netherlands and Luxembourg were hit by catastrophic flooding caused by the Bernd low-pressure system.

In Belgium, the most affected catchment (the Vesdre River) had experienced repeated summer droughts in the four years (2017-2020) preceding the flood.

This seminar will provide an overview of how a rare hydro-meteorological event combined with unfavourable hydrological conditions in the catchment and a lack of risk awareness and preparedness, which was plausibly exacerbated by the preceding prolonged drought.

Flood risk Baden-Württemberg - Are we prepared?Flood risk Baden-Württemberg - Are we prepared?

At the invitation of the Lions Club Karlsruhe-Baden, Dr. Peter Oberle on December 7th in the Schlosshotel Karlsruhe the current flood strategy of the state of BW.

The flood disaster of 2021 showed that the current design values for protective measures need to be reconsidered and that the intensities of historical events must be used as a basis, especially for alarm and operational planning. The results of a simulation study (in cooperation with Hydron mbH) for the Neckar Valley are presented, in which the precipitation from the 2021 flood was projected onto the catchment area there. The discharges in the Neckar Valley are comparable to the historic flood of 1824, with devastating consequences for the industrial sites located in the river valley. The BW state government provides comprehensive information (including hazard maps, forecasts) and tools in order to be prepared for such extreme events. The lecture ends with an appeal to the municipalities and each individual to take advantage of the offers and face this challenge.

New measurement methods to improve design and safety of hydraulic structuresNew measurement methods to improve design and safety of hydraulic structures

Hydraulic structures, such as dams fulfill many societal functions including water supply, flood mitigation and generation of hydropower.

Their safety is paramount and a failure can be catastrophic.

The design of hydraulic structures must therefore be conducted with the highest technical standards using state-of-the-art measurement approaches.
