Abstract: Particularly during extreme events, precise knowledge of the discharges in flowing waters is of great and decisive interest. However, Conventional measurement methods reach their limits precisely then, as they often rely on a sensor that is not contactless. Image-based flow measurement systems offer a flexible non-intrusive alternative with real time measurement. Unlike conventional measurement methods, the ratio of measurement signal to measurement noise is optimal for extreme events. The presented approach provides the users with digitised data, proof images and flood alarm on time. In the present paper, two extreme flood events are presented, which occurred under completely different conditions.
