MV Surf- und Kajakwelle Mur - MV surf and kayak wave Mur

The Institute of Hydraulic Engineering and Water Resources Management prepares a full and a detailed model to prove flood safety at different water levels and to make basic statements about bed load behaviour. After the model has been built and the necessary infrastructure (water cycle and measurement technology) has been set up, the model is then "calibrated". During this process the model is "adapted" to nature or the scale "reduction" of "nature" to laboratory conditions. The various representative water level measurements are carried out on the model according to the hydraulic specifications of the planning office and compared with the discharge calculation of the planner. As a rule, the spectrum of the runoffs examined in this process ranges from "low water runoffs" to the occurrence of a "hundred-year flood event". The aim is to keep the differences between measurements in the laboratory and the planner's specifications as small as possible. After finishing the calibration, the installation (surf and kayak wave) and the required tests can be started. The results of the tests can - from experience - be transferred well into nature. In order to be able to meet the requirements of the model test in the best possible way, the path "from the full model to the detailed model" has proven to be very practicable over many years.
