Overview

Randomized trial demonstrates changes in shoreline dynamics in an arid region, indicating environmental sensitivity.

Key Points

  • The aim is to analyze shoreline dynamics and environmental factors in an arid coastal region impacted by hurricanes.
  • Conducted analysis along a 58 km coastal stretch using CoastSat from 2020 to 2026.
  • Utilized 457 Sentinel-2 satellite images for automated shoreline analysis under specific tidal conditions.
  • Employed an autoregressive distributed lag model to assess factors influencing shoreline movement.
  • Observed sea-level rise of 2 mm/year consistent with Pacific averages (1.8 to 3.8 mm/year).
  • Most significant shoreline erosion of −19.7 m attributed to infrastructure disruption; positive accretion of up to 5.9 m in less developed areas.
  • Identified wave energy and hurricane-driven wind gusts as primary agents of shoreline retreat.
