Lecture 6 Field Exercise for Current Metering I. Introduction • • In this field exercise, we will do current metering in a canal, at the same locations as the flume from the previous field work We will use three current meters: 1. A Price current meter; 2. A Marsh-McBirney electromagnetic current meter; and, 3. An Ott-type current meter. • • The results of the current metering will be compared to the known calibration of a measurement flume You will write this up as a homework exercise with the following sections: 1. 2. 3. 4. 5. 6. • • Date, location, participant names; Introduction (describe what was done); Procedure; Data analysis; Summary & conclusions; and, References and or bibliography. Include a few digital photographs in the report (we will bring a camera) You may turn the report in by groups, if desired, but everyone in the group must contribute significantly to the work II. Field Activities (Procedure) • • • Dress appropriately for field work Use the current meters to measure the flow rate Measure the upstream & downstream depths at the flume, including the water surface elevations BIE 5300/6300 Lectures 59 Gary P.
