Het roer om: een analyse van de meetapparatuur in de rivier Roer

The floods in Limburg in July 2021 led to considerable material and emotional damage. To prevent and limit damage in the future, the importance of being able to predict a potentially dangerous water level is high. Then measurements can be taken on time and people can be warned or even evacuated. A prediction is based on a model, which in turn is based and validated with field measurements. Hence it is important that the measurements are reliable and valid. In this project, the quality of current measurement techniques for water levels and discharges in the Roer are evaluated. Possible improvement is also recommended. The location and type of each measurement gauge is analysed. Based on data on water levels and discharges, irregularities are mapped out. This analysis even goes into the causes of the missing data. This allows for an indication of the flaws of current measurement devices. This project has been limited to the Dutch part of the Roer.
