A wave of period 10 s is propagating toward a rubble mound breakwater in water of constant depth h = 30 m. A pressure gage located at 10 m from the bottom in front of the breakwater shows a time record with an envelope beating between minima of amplitude 2,100 N/m2 and maxima of amplitude 4; 700 N/m2. Calculate the rate (per meter of width) at which energy is dissipated by the breakwater. At what separation distance do the pressure maxima occur?
