We had the great opportunity to participate in the ADCP Regatta in Vranov nad Dyjí, organized by the Český hydrometeorologický ústav (Link: https://www.chmi.cz/?l=en). 24 measurement teams from 5 countries participated with more than 43 different measuring devices to test the accuracy of the devices and to facilitate professional exchange between the teams. Colleagues from the Hydrometry Department represented the Federal Office for Water Management with two modern ADCP measuring devices to test the quality of flow measurement in rivers and to exchange experiences across borders.
Why are comparison measurements important?
- Modern flow measurement devices like ADCP require new approaches such as comparison measurements for quality assurance.
- Regular comparison measurements help identify systematic and random errors.
- Comparison measurements enable the evaluation of measuring devices, methods, and teams, leading to consistent and reliable data quality.
Comparison measurements are crucial to maintaining the accuracy and comparability of flow data, which, for example, form the basis for flood forecasts, at a high level in the future.
