Title

DETERMINATION OF LONGITUDINAL DISPERSION COEFFICIENT INVOLVING TRACER EXPERIMENT DATA

Pages

  653-662

Abstract

 Longitudinal dispersion coefficient is normally affected by many HYDRAULIC PARAMETERS. So far three approaches namely, integral method, dye tracing filed measurements and empirical formulae have been widely employed to estimate the above mentioned coefficient in rivers and streams. In this paper a new equation of the longitudinal dispersion coefficient is devised and evaluated using an environmentally safe TRACER plus the basic EMPIRICAL EQUATIONs. To achieve the aim, a length of 500 meters of a manmade concrete canal was chosen, to be used in carrying out the TRACER tests. A set of experiments were conducted in Feb.2015, within three different MIXING LENGTHs, of: 45, 75 and 100 meters. The results show that differences of average, variance and maximum concentration between the measured vs estimated data using the lastly available equation) are equal to 79, 6, and 99 mg/lit while using the newly equation found in the present study they are respectively equal to 66, -1 and 44 mg/lit.
