Abstract: For a channel with a deep and a shallow region an eigenvalue-eigenfunction solution is obtained for the dispersion of effluent released in either the deep or shallow region. Each region is assumed to have a constant velocity and constant dispersion coefficient and the boundary condition at the discontinuity is the equality of mean concentration and concentration flux. The results are compared with experiments and are in qualitative agreement. Both experiment and theory show that if rapid initial dilution is important there is a great advantage in releasing the effluent in the deeper region.
