Laboratory experimental researches were conducted to study the influence of the pile shape of permeable vertical breakwater on the formation and transformation of surface waves. The experiments conducted in a wave channel, where waves of different heights, periods and wavelengths were generated, with permeable breakwaters of a fuel structure with piles of circular, square and triangular cross-section. The use of a group of sensors made it possible to determine the features of wave transformation during their interaction with single-row permeable vertical walls. Regardless of the direction of the frontal surface of the square cross-section piles of permeable breakwaters, the height of the reflected and transmission surface waves increased and the increase coefficient increased with increasing steepness of the incoming wave. The height of the reflected wave significantly exceeded the height of the transmission wave. With increasing permeability of the vertical single-row pile breakwater, the steepness of the reflected wave decreased, and the steepness of the transmission wave, on the contrary, increased. The highest ratios between reflected wave heights and transmitted wave heights as a function of normalized wave number were recorded for breakwaters with a permeability of 20%, which consisted of square-section piles, where the side of the square was directed towards the incoming wave. The lowest ratios between reflected wave heights and transmitted wave heights as a function of wave number were observed for breakwaters with a permeability of 50%, which consisted of square-section piles, where the edge of the pile was directed towards the wave.
