Abstract

Die Erfindung betrifft ein Verfahren zur Messung des Wasserstands eines Gewässers. Dabei wird ein Reflektor (1, 101, 201, 301, 401, 501) verwendet, der eine Anzahl von Re flexions flächen (1a, 1b) zur Reflexion von elektromagnetischer Strahlung in einem vorbestimmten Wellenlängenbereich umfasst und in oder an dem Gewässer derart bereitgestellt ist, dass durch die Wasseroberfläche (W) des Gewässers und eine oder mehrere Re flexions flächen (1a, 1b) des Reflektors (1, 101, 201, 301, 401, 501) ein Winkelreflektor gebildet wird. Im Rahmen des Verfahrens fällt elekt- romagnetische Strahlung in dem vorbestimmten Wellenlängenbereich, welche von einer oberhalb des Gewässers befindlichen Strahleinrichtung (3) ausgesendet wird, derart auf den Reflektor (1, 101, 201, 301, 401, 501), dass die einfallende Strahlung an dem Winkelreflektor basierend auf einer Mehrfachreflexion unter Einbeziehung der Wasseroberfläche (W) rückreflektiert wird. Über die Laufzeit der ausgesendeten und rückreflektierten Strahlung wird der Abstand zwischen Strahleinrichtung (2) und Reflexionszentrum des Winkelreflektors gemessen und hieraus der Wasserstand (W) des Gewässers ermittelt.
