Description of a model of fluid waste discharges in an estuary involving relationships between the waste load, the location of discharges, the degree of treatment, the geometry of the estuary, the flow in the estuary, and the temperature. Since present computational techniques are inadequate to deal with the three-dimensional computations of fluid flow and the complicated boundaries of estuaries, vertical integration of the equation of motion and continuity is used to reduce the problem to a two-dimensional one. The discrete values of the variables are described on a grid, using a space-staggered scheme, in which water levels and velocities are described at different grid points. Since mass densities are described at the same location as the water levels, there exists in the formula, operated upon in time, a centrally located spatial derivative for the linear term. Water levels and mass densities are computed on graphical displays of the outline of the bay with grid points. (See also RM-6230.)
This publication is part of the RAND paper series. The paper series was a product of RAND from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
