In engineering and civil structures, a pier refers to an artificial jetty or platform built out from dry land into a body of water. These structures serve multiple purposes, including providing docking facilities for vessels, supporting industrial installations, or creating pedestrian pathways. The construction of a pier requires detailed consideration of the local hydrodynamics, necessitating foundational supports that anchor the structure against forces such as currents, tidal shifts, and wave action. Materials used for construction must exhibit resilience and durability against prolonged exposure to marine or riverine environments.
