Abstract: The presently disclosed subject matter aims to a system and method including a processing circuitry configured to: obtain: (a) a plurality of independent wave measurements of a body of a fluid, obtained over a period of time, wherein each independent wave measurement is acquired at a distinct location of the body of fluid; and (b) a respective ambient shearing current profile, wherein the respective ambient shearing current profile is based on ambient current values and directions, at different locations within the body of the fluid, related to the respective distinct location; based on the wave measurements and ambient shearing currents profile, assess wave directional spectra characterizing flow regime of waves of the body of fluid, while accounting for the effects of the ambient shearing currents during the wave measurements' period of time; and determine, based on the assessed wave directional spectra, one or more design parameters of the maritime infrastructure.

Abstract: A probe, for determining local shear stress on the face of a solid surface caused by relative movement between it and a fluid, comprises a 3-dimensional array of seven spaced electrodes constituted of: one electrode at the center of the array, two electrodes equally spaced from said center electrode along a first line through said center, two electrodes equally spaced from said center electrode along a second line through said center and perpendicular to said first line, and two electrodes equally spaced from said center electrode along a third line through said center and perpendicular to said first and second lines. The probe further includes magnetic means for producing a magnetic field in the region of the electrodes.
