Point Source Dispersion in Turbulent Open Channels
The effect of the initial distribution of dispersant is investigated by obtaining solutions corresponding to different initial instantaneous point and plane source distributions. The governing equations are converted to a tractable system of moment equations which is solved by numerical methods with the aid of a digital computer for the zeroth, first, second, third, and fourth moment of the longitudinal concentration distribution. The initial instantaneous point source distribution is located at η0 = 0, 0.25, 0.50, 0.75, and 1.0. During the initial period of dispersion, the convective transport produces a considerable change in the moments of the dispersing cloud as compared with the Gaussian long dispersion time behavior, and the longitudinal dispersion in a turbulent open-channel flow is strongly dependent on the location of the instantaneous point source.
