of various features of inshore circulation can be pointed out and ex- 

 plained simply and easily. The student can use the model to obtain 

 data corresponding to field measurements, and then work it up in the 

 usual manner. 



Summary and Conclusions 

 An hydraulic model of Puget Sound has been built and tested under 

 various conditions. Equipment for controlling and measuring the 

 oceanographic variables has been designed and put into satisfactory 

 operation. Prototype tide and current are well represented by those in 

 the model. It has been demonstrated that density structure similar to 

 that in nature can be obtained by proper control of operating condi- 

 tions, but no detailed comparison has been made between prototype 

 and model structure under corresponding conditions.
