Executive Summary :

The project aims at applying a well-tested entropy concept and approximate flood stage hydrograph routing method for discharge estimation and development of stage- discharge relationship at three selected sites of Godavari River basin. In this project, the surface flow velocity would be monitored by using non-contact sensors which allows to achieve a good estimate of discharge by exploiting the entrophy theory applied to the velocity distribution and subsequent average velocity estimation in natural channels and without requiring the complicated estimation of parameters as in the classical velocity distribution laws. These instruments use sensonrs based on cutting edge radar technology for continours, reliable, non-contact measurement of water level and water-surface velocity. The exepected outcomes of the project are; i) Establishment of next generation flow measurement stations at three sites on Godavari river equipped with radar type velocity and water level sensors for real time continous discharge estimation as well as for rating curve development at these sites, ii) Detailed technical document consisting of description of site development, methodolgies employed, User manuals describing operation prcedures, User manal for processing of data and iii) user manjual for the developed software toll meant for development of stage discharge relationship and discharge estimation.

Outcome/Output:

Non-contact real-time discharge measurement stations were successfully established on two major gauge stations situated in the lower Himalayas The study was the first of its kind where such a large amount of ADCP and non-contact discharge observations were taken for mountainous rivers in India.
