Overview

Due to the existing infrastructure with different experimental flumes and pump systems, as well as easily accessible areas for temporary model test setups, the Hydraulic Engineering Research Laboratory offers excellent conditions for work in the areas of hydraulic engineering experiments, basic research, application-related contract research, and for targeted integration into teaching.

Hydraulic Engineering Testing

The Hydraulic Engineering Research Laboratory (HERL) supports and complements sophisticated planning and concepts through experimental investigations. One focus of the HERL's work is on new disciplines from the interface of engineering, natural and environmental sciences, among which ethohydraulics and ecohydraulics can be mentioned in particular. In addition, the work of HERL includes modeling and simulation of structures in the field of hydraulic engineering and water management. The direct link with hydrodynamic-numerical modeling in hydraulic engineering provides the best prerequisites for “hybrid modeling”. Thus, the combination of computer-aided and physical experiments with the respective advantages of both methods provides a timely approach to the solution of various problems.

In addition, HERL, with its associated personnel and technical equipment, offers to perform in situ measurements (multi-dimensional point flow velocity measurements, flow velocity profiles, particle sampling, sieve analyses, etc.).

Various laboratory facilities and measuring instruments are available for the experimental investigations, which are carried out both for the direct processing of hydraulic engineering problems and for the calibration of numerical models. These are presented in detail on the page Measuring equipment.

Integration of the Research Laboratory into Teaching

Within the framework of teaching, students are to be given the opportunity to become acquainted with hydraulic engineering experimentation. For this purpose, numerous teaching test rigs are available for use in the gallery of the research laboratory. These are mainly used in the course Laboratory Internship in the Hydraulic Engineering Research Laboratory . Impressions of the test rigs can be gained in the Picture Gallery (Test rigs) .

Furthermore, there is a so-called “Stream Table” in the Research Laboratory, in which river morphological developments can be illustrated with sand. The stream table will be examined more closely in the course Water Dynamics .

General tours of the research laboratory are also given as part of various hydraulic engineering courses.

State Testing Agency for Flow Measuring Devices and Throttling Elements

The inspection of the flow measuring devices relevant for the discharge at wastewater treatment plants as well as throttling devices at rainwater spillways and retention basins is carried out by “state inspection bodies” and “recognized inspection bodies” according to § 11 (1) of the self-monitoring ordinance (EKVO) on behalf of the self-monitoring parties.
