Note: I. Experimental points corresponding to the some value of the ratio ^/H are 

 connected by continuous curves. 



2. The comparative curve with the angular point was figured from equations 2and3, 

 using the values given for >v and Y, (whence YJ and an'intrinsic" coefficient of 

 reflection 9 - 0.7 



3. The point marked P is that given by the Irriborren formula.

 Note: I. Experimental points corresponding to the some wove length-woter depth rotio ore 

 connected by continuous curves. 



2. Comporative curves with angular point were figured from equations 2 ond 3, using an 

 "intrinsic" reflection coefficient p - 0.33 



3. Points marked Pore those given by Irriborren's formula.
