Steady-state solutions to the diffusion-advection equation are obtained for waste discharges under the following conditions: a vertically well-mixed ocean with a coastline and a steady, uniform current parallel to the coastline; a vertically well-mixed river with a steady, uniform current. The method of images is used to obtain solutions for these environments. It is assumed that the discharge contains a constituent whose decay characteristics can be described by a first order reaction. A listing of the FORTRAN 77 source code implementing the solution technique is provided in the report.
