Radioisotope Flow Measurements on the Friant-Kern Canal Central Valley Project Fresno, California
Radioisotope discharge measurements were performed on 2 sections of the Friant-Kern Canal during the period August 10-14, 1964, for the purpose of determining the water losses in the canal. A concrete-lined section between Friant Dam and Mile 29 and an earth-lined section between Mile 35 and Mile 53 served as the test reaches. Eight radioisotope injections were made, resulting in 24 individual discharge rate determinations. The discharge values obtained with the radioisotope measurements ranged from 2643 to 3128 cfs and were compared to the results of current meter measurements and the indicated discharge from the calibrated hollow-jet valves at Friant Dam. Measurement accuracies based on the above comparison were all within 9.5%, but many were within 2%. The integrated sample and pulse or 'total count' methods were used to determine the discharge with radioisotopes. A waterproof scintillation counter and 2 GM counters were used in the tests. New methods of field calibration of the immersed counter were tested successfully to calibrate the scintillation counter. (Author)
