Remote Sensing of River Discharge Based on Critical Flow Theory

Remote Sensing of River Discharge Based on Critical Flow Theory

Abstract Critical flow theory provides a physical foundation for inferring discharge from measurements of wavelength and channel width made from images. In rivers with hydraulically steep local slopes greater than ∼0.01, flow velocities are high and the Froude number Fr (ratio of inertial to gravita...
