Pre-Feasibility Study on Streamflow Gauging Using Radioisotope Tracer Method for Kemubu Agriculture Development Authority (KADA)

摘要

Measuring the flow rate of a water course is one of the basic operations in hydrology, relating to water problems and of particular importance in the planning of water control schemes. The techniques commonly used in streamflow gauging are either by a current meter or a tracer dilution method. This paper describes the latter technique in which radioisotope /sup 99m/Tc was used as a tracer in streamflow measurements performed in 1983 in a few selected irrigation canals and pump house under the Kemubu Agriculture Development Authority (KADA), Kelantan. Total count technique and peak-to-peak method were adopted in this study. (ERA citation 12:027431)
