The measurement of high discharges in turbulent rivers using tritium tracer

Abstract Use of tritiated water as a tracer for measurement of flow rate in turbulent rivers offers a promising technique for high flows where other methods are not feasible. Examples of application are given from flow gauging in River Tana where flows from 100 to over 500 m 3 /sec have been measured and compared with rating curves. Tritium technique proved to be accurate, easy to use in remote areas and applicable for high flow-rates.
