Second order analysis of dynamic pressure profiles, using measured horizontal wave flow velocity component F.T. Pinto & A.C.V. Neves Institute of Hydraulics and Water Resources, Faculty of Engineering, University of Porto, Portugal Abstract There is an increasing need for pressure field knowledge under wave flows due to its importance in coastal structure design. Several studies have been conducted in such a way as to accurately learn the behavior of those pressure fields in trying to define reliable formulae for design purposes, describing with a better degree of detail the maximum values achieved as well as the stochastic aspects of the wave action. This article intends to present the evolution of pressure fields under the action of incident regular waves, as a function of its phase and relative depth, comparing them with a linear and a second order wave theory. These wave fields were obtained in an indirect way, through the horizontal wave flow velocity component. The measurements were ca
