THE MEASUREMENT OF RIVERFLOW WITH RADIOACTIVE ISOTOPES WITH PARTICULAR REFERENCE TO THE METHOD AND TIME OF SAMPLING

METHODS OF RIVERFLOW GAUGING WITH RADIOACTIVE ISOTOPES INVOLVING WITHDRAWAL OF SAMPLE FROM THE RIVER AND MEASUREMENT IN SITU ARE INVESTIGATED IN STREAMS OF 10-250 CUSECS. THE TOTAL COUNTS METHOD IS FAVORED ON ACCOUNT OF ITS ABILITY TO SAMPLE LARGE VOLUMES AND IS FOUND TO GIVE RELIABLE RESULTS AT SHORT SAMPLING DISTANCES. AN EXTENSION OF THE METHOD TO CONDITIONS OF NON-INFINITE GEOMETRY USING A PROBE IN THE STREAM IS OFFERED. THE EXTENDED METHOD ALLOWS IN SITU GAUGING OF STREAMS AS SHALLOW AS TWO FEET. AN EMPIRICAL METHOD FOR PREDICTION OF TRACER PASSAGE TIMES FROM TRACER ARRIVAL TIMES IS GIVEN, BASED ON A SERIES OF MEASUREMENTS OF TRACER PASSAGE IN RIVERS AT LOW FLOW. THE MERITS OF COLLOIDAL GOLD AND CHROMIUM EDTA AS TRACERS FOR RIVERFLOW GAUGING ARE DISCUSSED. COLLOIDAL GOLD WAS FOUND TO BE INSIGNIFICANTLY ADSORBED OVER A MEASURING REACH OF 3,000 FT. /AUTHOR/
