An environmental summary created by the ENVS 560/L Watershed Systems class at CSUMB.

This page gives a background on Coastal Retreat in California's Central Coast Region and highlights scientific findings pertaining to coastal erosion.

Summary

The Southern Monterey bay region has some of the highest coastal erosion rates in the state of California.[1]

Monterey: 1 ft / year

Seaside: 3 ft/year

Marina: 6 ft/ year

Science

Coastal Retreat in California's Central Coast Region, specifically Southern Monterey Bay, has the fastest rate of erosion in California.[2] Since the retreat is occuring in the Monterey Bay National Marine Sanctuary, scientists are determined to find possible mitigation efforts, reasons for high rates, and, specific hot spots.

Recent research includes:

  • Sand Mining Impacts on Long-term Dune Erosion in Southern Monterey Bay [3]
  • Sediment distribution and transport along a rocky, embayed coast: Monterey Peninsula and Carmel Bay, California [4]
  • Coastal Regional Sediment Management Plan For Southern Monterey Bay [5]
  • National Assessment of Shoreline Change Part 3: Historical Shoreline Change and Associated Coastal Land Loss Along Sandy Shorelines of the California Coast [2]

Tools

There are a variety of tools that can be used to assess the effects of sand mining and/or coastal retreat.

  • ArcGIS and the Digital Shoreline Analysis System (DSAS) toolbox can be used to monitor changes in beach width.
  • Stero Photogrammetry [3]
  • LIDAR Measurements [3]
  • GPS Surveys [3]
