FIELD OBSERVATION OF THE PULSATORY FLOW VELOCITY BY RADIO CURRENT METER

Abstract

Radio current meters were improved in a turbulence measurement version and pulsatory flow measurement was made every 0.3 sec in 7 reaches of 4 different rivers in order to applicability check of the version. 5 items (V, Vave, E, Eave, E0.3-3Hz ( E : Radio Reflection Intensity ))are chosen and succeeded in observation of periodical characteristics in some items and irregular signs because of bursting from the river bed.
