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 report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation 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.
Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
