• the front portion is in the form of a juxtaposition of arched walls extending in a longitudinal direction that is vertical;
• wherein
• each arched wall presents a concave side facing the first portion of ground and a convex side facing the second portion of ground;
• and wherein
• the retaining work further includes a rear portion connected to the front portion and comprising a plurality of wall elements having their largest faces extending vertically in the second portion of ground, each wall element being arranged between two adjacent arched walls and extending transversely relative to the front portion;
• and wherein the first portion of ground is situated under the bottom of a body of water such that the front portion separates the body of water from the second portion of ground;
• wherein the wharf further includes a first rail that extends transversely relative to the wall elements of the rear portion while being supported by a plurality of said wall elements, and wherein the wharf further includes a second rail parallel to the first rail.
