COMPUTER - IBM 7094 



PREDICTS THE HORIZONTAL STEADY STATE DISTRIBUTION OF A CONTAMINANT DUE 

 TO HORIZONTAL ADVECTION AND DIFFUSION WHEN DISCHARGED AS A VERTICAL 

 PLANE SOURCE OF UNIT DEPTH AND UNIT RATE OF DISCHARGE AND LOCATED PER- 

 PENDICULAR TO A BOUNDARY. THE VELOCITY IS ASSUMED TO BE CONSTANT. THE 

 OKUBO-PRITCHARD MODEL FOR AN INSTANTANEOUS RELEASE IS USED. IT IS IN- 

 TEGRATED LATERALLY TO TRANSFORM A VERTICAL LINE SOURCE SOLUTION TO A 

 SOLUTION FOR A VERTICAL PlAnE SOURCE AND IS TOTALLY RELECTED Aj THE 

 BOUNDARY TO QUANTITATE THE BOUNDARY EFFECT. AUTHORS — H.E. WALTERS 

 AND H.H. CARTER.

CONTINUOUS SOURCE IN TIDAL ESTUARY PER LANGUAGE - FORTRAN II 



UNIT DEPTH AND UNIT RATE OF RELEASE COMPUTER - IBM 7094 



PREDICTS THE CENTERLINE LONGITUDINAL DISTRIBUTION OF A CONTAMINANT AS 

 A FUNCTION OF PUMPING TIME, DUE TO HORIZONTAL ADVECTION AND DIFFUSION 

 WHEN DISCHARGED AS A VERTICAL LINE SOURCE OF UNIT DEPTH AT A CONSTANT 

 RATE IN A TIDAL ESTUARY. INPUT ARE THE MAXIMUM TIDAL VELOCITY, THE 

 NON-TIDAL VELOCITY, THE DIFFUSION VELOCITY I.E. SPREADING COEFFICIENT, 

 A MEASURE OF HORIZONTAL DIFFUSION, PUMPING TIME I.E. TIME SINCE SOURCE 

 WAS INITIATED, AND THE LONGITUDINAL DISTANCE FROM THE SOURCE, STORAGE 

 NECESSARY — 15000 WORDS (CAN BE EASILY CHANGED TO 7000 WORDS). AUTHORS 

 - H.E. WALTERS AND H.H. CARTER.

CONTINUOUS SOURCE IN TIDAL ESTUARY PER UNIT DEPTH LANGUAGE - FORTRAN II 

 AND UNIT RATE OF RELEASE, WITH COOLING TERM COMPUTER - IBM 7094 



PREDICTS THE CENTERLINE LONGITUDINAL DISTRIBUTION OF HEAT AS A FUNC- 

 TION OF PUMPING TIME DUE TO HORIZONTAL ADVECTION, DIFFUSION. AND AT- 

 MOSPHERIC COOLING WHEN DISCHARGED AS A VERTICAL LINE SOURCE AT A CON- 

 STANT RATE IN A TIDAL ESTUARY. THE OKUBO-PRITCHARD MODEL FOR AN IN- 

 STANTANEOUS RELEASE IS USED FOR THE MODEL. IT IS FURTHER ASSUMED THAT 

 EACH INFINITESIMAL RELEASE COOLS EXPONENTIALLY WITH TIME. THE RATE CO- 

 EFFICIENT IS CALLED THE COOlING COEFFICIENT. CORE STORAGE NECESSARY-- 

 15000 WORDS (CAN BE RUN USING 7000 WORDS). AUTHORS — H.E. WALTERS AND 

 H.H. CARTER.
