A schematic representation of mean water level and extreme or total water level referenced to a beach complex

a) A schematic representation of mean water level (h₅₀) and extreme water level (h₉₈, (or total water level) referenced to a beach complex where beach slope (b_m), shoreline, dune base (z_b), and dune crest (z_c) have all been calculated. b) The models used and calculations employed in the predictive model in order to determine the storm impact regime for a beach during an elevated water event (typically, but not restricted to, a hurricane).
