The characteristic kinematic scaling factors used in the 

 Barataria Bay model construction and operation are as follows; 



L, horizontal length scale 1/20,000 



y,. vertical length scale 1/192 





vertical distortion 

 factor 





Uj. = 0.025 V^ 



time scale 



velocity scale 



discharge scale (total) 1/53,000,000 



kinematic density scale l/l 



wind scale 



192/20,000 = 1/104 

 1/1440 = 1 min./"day" 

 1/13.8(3) = 3.65 cm/sec/"kt" 



(empirical calibration) 



The approximate physical dimensions of the Barataria Bay model 

 are given to provide some acquaintance with the scale of the model 

 experiments. About six months of effort by sixteen part- and full- 

 time craftsmen were required to build the model and its auxiliary 

 equipment.
