13. ABSTRACT 



The dynamic pressure on the sea bottom due to a constant, rec- 

 tangular pressure distribution moving at a steady speed over the 

 calm- water surface is determined. The problem is formulated and 

 solved within the framework of potential-flow, linear-wave theory. 

 Numerical results are presented for one beam-to-length ratio, for 

 various water depths, and for both subcritical and supercritical 

 speeds.
