The solution technique utilized by each model should be specified by the following number code: (I) Phenomenological (2) Analytical (3) Finite Difference (4) Integral (5) Finite Element (6) Stochastic (7) Other (state) d. Approximation. Simplifying approximations to the mathematical formulation of the model should be indicated by one or more of the following: (1) Steady State (2) Boussinesq (3) Hydrostatic Pressure (4) Buoyancy Decoupling (5) Other (state) "Other" approximations applied to each model should be discumed in the text. e. . Model Verifiatibo. Efforts to verify the model by field and/or laboratory measurements should be indicated in the MAT and described in the text. f. Computer Program. The availability of a computerized version of the model should be specified by one of the following: (1) Proprietary (2) Available on request (3) Available in open literature (4) No program exists. 4.4-4 MODEL > ASSESSMENT o TABLE _ __ _ SINGLE PORT TYPE MULTIPORT ROUND RECTANGULAR LCTOSHORELINE SLOCATION O F H R OFFSHORE_________ SURFACE ____ O POSITION SURMECE (n SUBMERGED oa HORIZONTAL DIRECTION NON-HORIZONTAL VOLUME FLOW RATE (M3 /SEC) ___L__ DISCHARGE VELOCITY (M/SEC) EXCESS TEMPERATURE (deg C) TYPE z r DEPTH AT OUTFALL (Ml __,__,_ Lu BOTTOM SLOPE (dgeg) W_ ~ NATURAL STRATIFICATION S CRNSPEED (M/SEC) R DIRECTION (degL) JET ENTRAINMENT FROUDE NUMBER LONGITUDINAL ___-__________ ENTRAINMENT LATERAL COEFFICIENT LATERAL Oz VERTICAL _ __ _ Z 0 CROSS FLOW SVELOCITY RATIO U <PRESSURE DRAG W Lu DRAG COEFFICIENT _ _,_"_ Lj Z NATURAL TURBULENCE EDDY LONGITUDINAL ,_______ 1: cc DIFFUSIVITY LATERAL _,,_"___ ___ U) VERTICAL _______ S WIND STRESS BUOYANCY " RECIRCULATION SURFACE HEAT TRANSFER HEAT TRANSFER COEF (CALJM2 SEC-de C) ,_"_ EQUILIBRIUM TEMPERATURE (deg C) _,_____ FIELD , ' LONGITUDINAL •, " DIMENSION LATERAL _ _ __ uj 0 1 VERTICAL ,' " MATHEMATICAL APPROACH f .
