Revisiting hull pressure wave

A while back the topic of not being able to achieve hull speed due to a downward pressure wave interacting with a relatively shallow bottom. My interest still runs high in finding a formula to relate length-at-waterline and velocity to the depth that it comes into play, and the affect as depth decreases past that threshold. Any help would be appreciated. Bill
