Jaugeage par radar mobile, protocole et résultats

Abstract : The non‑contact surface velocity measurement using SVR (Surface Velocity Radar) can be used to measure river discharge during floods. This method convinces hydrometry services because it is quick and simple to apply. The SVR is a complimentary instrument to add to the field panoply, especially for flood measurements. For computing discharge from surface velocities, additional measurements (bathymetry, velocity profiles, water level) are needed, and a velocity coefficient has to be estimated for each site. Mean velocity and surface velocity are linked through this coefficient. This study explains the field procedure suggested by Irstea (National Research Institute of Science and Technology for Environment and Agriculture) for gauging streams with a SVR system, with a two‑way procedure to improve the discharge measurement accuracy during fast flood with fast water level variations. Some application results are presented in different rivers, with a comparison between the radar method and other conventional discharge measurements. The quality of the results is very encouraging.
