01 / OBJECTIVE

Map the spit shoreline topography before winter storms to measure seasonal sediment volumes washed away from rock breakwaters.

02 / SOLUTION

Flew standard coastal flight lines at low tide with high-density laser sweeps. Filtered visual seaweed and drift grass out using LiDAR multiple return algorithms.

03 / OUTCOMES

Mapped 4.2 miles of spit shorelines, identifying sediment loss profiles of 120 cubic yards along the southern breakwater wall for target municipal maintenance.
