244 Long Waves in Canals and Standing Waves in Closed Basins 



Cochrane and Arthur (1948) have made a theoretical investigation of 

 such a reflection. The data examined give good evidence that reflections of 

 tsunami do occur. A quantitative treatment shows that the observed wave 

 heights were found to be in good agreement with those calculated on the 

 basis of theory. The theory indicates that the reflected waves can be expected 

 to be considerably smaller than the direct waves. This is also in agreement 

 with observations.
