The Coastal Commission voted Thursday to order a Laguna Beach couple to pay $1 million and tear down a seawall that is protecting a multi-million home. The seawall is illegal, officials say, and causes the public beach in front of the home to disappear. The homeowners say the law is on their side.

This article caught my interest because my research project focuses on the rate of erosion and the volume of sediment transport. In the past, geologists were limited to the use of surveying equipment to study erosion but this is a difficult task in places like Fort Funston of San Francisco, CA. This region is characterized by steep 160 ft. cliffs that have been eroding away significantly from exposure to waves, wind and precipitation. To get around this treacherous obstacle, USGS geologist Jonathan Warrick teamed up with Kenneth and Gabrielle Adelman. The pair have been taking aerial photos of the California coastline over several years. With the use of the historical photos, 3D maps of the beaches and cliffs have been created, showing areas of erosion and deposition. This is an awesome technique because it allows for the calculation of erosion trends, evaluation of processes that shape the coast and predictions for the impact storms will have in the future.

The seacoasts of California and nations on both sides of the Pacific are likely to be battered in coming years by increasingly high waves pushed ashore by ever-stronger weather patterns, leaving them vulnerable to destructive erosion, an international group of experts said Monday. Severe weather events across the entire Pacific basin have been increasing for more than 30 years, and are expected to double in frequency in coming years, the scientists said in a report published in the journal Natu
