|New 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.

On 25.07.2023 the company outgoing of the department Hydraulic Engineering and Water Resources Management took place.
First, we went by bike to a spot near the river Rhine called “Belle”. Fortunately the rainy weather could not affect the good mood, so everyone cycled on to the Rhine port steam power plant. Here the hard coal block RDK8 was shown to us, with focus on the inlet and outlet of the cooling water. Since the cooling tower is currently under revision, it was even possible to visit the cooling tower from the inside which was very impressive.
Back at the KIT, everyone enjoyed the relaxed barbecue together.
