 VII. SPECIFICATIONS OF THE MODEL TESTS 



The construction and verification of the Barataria Bay model 

 discussed up to this point was of a routine nature and followed 

 established precedents in most respects. The principal purpose 

 of the model was to reconstruct the probabljo distribution of the 

 maximum quantity of bleed water discharged at any time during 

 the sulphur raining operations of the Freeport Sulphur Company. 

 Toward this end apparatus was constructed which would discharge 

 these maximum specified volumes as traceable material into the 

 model at specified points under continuous discharge conditions. 

 In each case the aim of the experiment was to determine the 

 steady state distribution of the tracer under each of several 

 wind conditions and at each of two dilution figures, namely 1 

 part in 200 and 1 part in 1000, The specifications for these 

 discharge conditions were supplied by the Freeport Siilphur Com- 

 pany and are as follows; 



Test A. Investigate the progress and distribution in the model 

 of fresh water draining through the Barataria Bay estuary 

 from the watershed to the north of Barataria Bay, 



Test B. Investigate the distribution in the model of a tracer 



having theoretical kinematic similitude with specified bleed 

 water and capable of showing dilution by the ambient water 

 not in nominal excess of 1 part in 200 and 1 part in 1000 

 discharged at the points and at the rates given below:
