A systematic application of a zone-matching methodology is presented for simulating the plant induced flow field from interacting, submerged directional, multiport diffusers, in a coastal region with predominantly natural tidal flow. The diffuser-induced near-field flow is approximately represented as a superposition of radial jets. Each jet near-field flow is determined using a singular perturbation method so as to produce the upstream entrainment characteristic of multiport diffusers. The far-field diffuser-induced flow is determined numerically using a two-dimensional discrete element model. This flow field represents a higher order correction to the near-field flow which satisfies the no-mass flux condition on solid boundaries. Natural flows and other plant induced flows are simulated with the two-dimensional discrete element, hydrodynamic model. An application of this methodology to a three unit nuclear power plant in southern California is given. (Wassmann)
