Abstract

Protocols for rejuvenation of large to moderately-sized rivers using remote sensing data is well established in different parts of the world. With the advent of commercially viable drones, highresolution imageries in sub-centimetre level can be generated, and this has made the assessment of degradation of small rivers a reality. The Sakri is a small river in the state of Chhattisgarh, central India with a basin area of 410 km , channel width < 30m. Even with an average rainfall of 1232 mm, and a perennial source feeding the river, the river remains dry in most stretches. People from 23 villages and the town of Kawardha are mostly dependent on this river, and therefore, an attempt to rejuvenate this river was taken up using an innovative technology of drone surveys coupled with
