Modeled beach profile evolution at Parramore Island, Virginia
Animation displays modeled beach profile elevation as it has evolved at Parramore Island, Virginia. These data are based on geomorphic investigation and measure distance (in kilometers) of cross-shore accretion. QS is the flux of sand to the beach, and QD is the flux of sand from the beach to the active dune. Yellow represents sand, blue represents water, while green represents marsh.
