Abstract – The management of water resources depends, to a considerable degree, on the availability of hydrological and hydraulic data. The operation and maintenance of irrigation systems requires collecting regular data on water levels and discharges. The calibration of canal sections or structures provides information on canal discharges and hence supports the efficient day-to-day water management and regulation of irrigation systems. The Tungabhadra Dam is constructed across the Tungabhadra River, a tributary of the Krishna River. The dam is near the town of Hospet in Karnataka. It is a multipurpose dam serving irrigation, electricity generation, flood control, etc. This is a joint project of Karnataka, Andhra Pradesh and Telangana after its completion in 1953. The water level profiling was done by CWPRS at the CH 28 in mile 1 during August 2014, March 2015 and August 2015 using Acoustic Doppler Current Profiler (ADCP) and Current Meter.The measurements were performed simultaneously with the two methods to present a comparison of discharge measurement made by current meter which is the conventional method and latest developed technique, ADCP. Results show that the relative error is very small with the ADCP over the conventional method. Besides the total value of discharge, the ADCP method also offers detailed information about velocity distribution over the cross section.
