Wave Kinematics and Wave Bottom Pressures in the Surf Zone
Wave induced pore pressure and instantaneous liquefaction are known to occur and cause loss of bearing capacity of sand. The possible pressure fluctuation due to a series of plunging breakers is anticipated to yield liquefaction that will influence the conditions for erosion and the supporting capacity for structures. Wave bottom pressure forms the boundary condition for the wave induced pore pressure. It is believed that not only variation of the pressure itself, but also the variations of its first and second order spatial derivative play an important role in the formation of liquefaction. Experimental studies on water wave propagation over impermeable slopes have been carried out to provide important insight to the topic. In this investigation focus is on plunging breakers as these are expected to give the maximum pressure variability.
