FIELD MEASUREMENT OF BRIDGE-PIER SCOUR

AN ELECTRICAL APPARATUS, UTILIZING THE DIFFERENCE IN CONDUCTIVITY OF WATER AND A SAND-WATER MIXTURE, HAS BEEN DEVELOPED TO RECORD THE SCOUR DEPTH AT A POINT NEAR A BRIDGE PIER OR ABUTMENT. ROUTINE OPERATION OF THE INSTRUMENT AND COLLECTION OF AUXILIARY DATA CAN BE HANDLED BY AN ENGINEER OR LABORATORY TECHNICIAN WITHOUT SPECIAL TRAINING. THE INITIAL FIELD INSTALLATION, WHICH RECORDS DATA ON A STANDARD ESTERLINE-ANGUS RECORDER, HAS BEEN IN OPERATION ON THE SKUNK RIVER NEAR AMES, IOWA, FOR MORE THAN A YEAR. MORE MEASUREMENTS ARE NEEDED IN ORDER TO ESTABLISH MODEL-PROTOTYPE CONFORMITY. THE INSTRUMENT CAN ALSO BE USED AT SITES OF COMPLEX GEOMETRY TO ACCUMULATE DESIGN DATA. /AUTHOR/
