Abstract
The present invention is a method of determining a free surface elevation (ESL) of a water body zone. The method involves measurement by radar (MRA) and localized measurement using a drone (MDR) equipped with a sensor, in order to calibrate (CAL) a free surface elevation reconstruction model (MOD) in the considered zone. The calibrated model (MOD CAL) is subsequently applied to real-time radar measurements (MRA) in order to determine free surface elevation (ESL).

1-10. (canceled)
A method of determining a free surface elevation of a water body zone using radar and at least one drone each equipped with a sensor providing remote measurement of the free surface elevation, comprising the steps of:
- a. constructing a free surface elevation reconstruction model relating a signal measured by the radar to the free surface elevation;
- b. measuring with radar a signal representative of the free surface elevation of the water body zone;
- c. performing at least one measurement during flying of the at least one drone with the at least one sensor fitted to the at least one drone at a measuring point in the water body zone;
- d. using the at least one measurement to calibrate the free surface elevation reconstruction model;
- and
- e. applying the signal representative of the free surface elevation measured at the measuring point with the radar to the calibrated free surface elevation model to determine the surface elevation at the measuring point of the water body zone.
