Ocean Beach sand transfers will disrupt SF traffic on Great Highway
For the next two months, bulldozers, backhoes and dump trucks will dig up and ferry 75,000 tons of sand south from the beach’s northern shores in an effort to temporarily replenish precious coastline lost to the forces of nature and accelerated by the effect of climate change.
Seafloor erosion now occurring like coastal land loss
Scientists have discovered that the seafloor from the Mississippi River Delta to the Gulf of Mexico is eroding like the land loss that is occurring on the Louisiana coast. During the 20th century, thousands of dams were built on Mississippi River tributaries stopping the flow of fine silt, clay and other sediment from reaching the delta and seafloor to offset erosion.
Human-Engineered Changes on Mississippi River Increased Extreme Floods
A new study has revealed for the first time the last 500-year flood history of the Mississippi River. It shows a dramatic rise in the size and frequency of extreme floods in the past century—mostly due to projects to straighten, channelize, and bound the river with artificial levees. It also uncovered a clear pattern over the centuries linking flooding on the Mississippi with natural fluctuations of Pacific and Atlantic Ocean water temperatures.
Illegal beach scraping practices in Florida
Four beachfront homeowners are receiving warnings from state for removing sand from beach with machinery to create a “small frontal dune at the base of the original eroded dune.” The practice of ‘beach scraping’ was common during the early part of the 1900s, but improper practices eventually led to state regulation.
Who knows where the sand goes?
After years of rebuilding Delaware Bayshore beaches decimated by Hurricane Sandy, the American Littoral Society and its partners have developed a computer tool to help predict where the sand will travel.
Hotting up: how climate change could swallow Louisiana’s Tabasco island
With thousands of square miles of land already lost along the coast, Avery Island, home of the famed hot sauce, faces being marooned.
First lorry-load of sand arrives at storm-hit Hemsby beach, UK
Work has started to replace sand stripped away from a beach, following storms which left a row of houses perched on the edge of a cliff.
Easter Island is critically vulnerable to rising ocean levels
Nicholas Casey, a New York Times correspondent based in Colombia, and Josh Haner, a Times photographer, traveled 2,200 miles off the coast of Chile to see how the rising ocean is erasing the island’s monuments.
Maps show Northland coastal erosion and flood threat to homes; NZ
Climate change, storm surges, tsunamis, earthquakes and poorly placed human footprints could all increase the risk of flooding and coastal erosion at sites identified on Northland Regional Council’s new coastal hazard maps.
