Abstract: A computerized data acquisition system has been developed that is based on a Hewlett-Packard 9845B desktop computer. The system allows determination of highly accurate water temperatures, flow rates, and pump characteristics, and control of a flume-mounted motorized carriage that provides a platform for an ultrasonic depth transducer. This depth transducer allows acquisition of bed form information for sediment transport work or ice ripple form information for heat transfer work. Alternatively, linear variable displacement transducers may be used to profile ice surfaces. Data acquired can be displayed numerically or graphically and are stored on floppy disks.
