Abstract

The report deals with the mixing of a dissolved passive pollutant permanently released into a water stream. It assumes the velocity field as being known and makes use of the equation of turbulent diffusion, describing the said phenomenon by the introduction of depth-averaged values, in a co-ordinate system consisting of streamlines and equipotential lines normal to them. It defines the curves of mass flux constant which divide the original differential equation into two equations, more convenient to handle computationally. The report outlines certain characteristics of the curves, and deals with the computation of the distribution of the concentration, respectively, with the inverse case: the determination of the dispersion coefficients obtained by tracer measurements.
