Puerto Rico Takes Steps Against Erosion to Save 32 of its Beaches
Puerto Rico is preparing measures to halt the erosion that is seriously diminishing at least 32 of its beaches.
Largest Dam Removal in U.S. History Scientifically Characterized: A USGS Lecture on Largest U.S. Dam Removal
Scientists worked together to characterize the effects of the largest dam removal project in U.S. history occurring on the Elwha River of Washington State. New findings suggest that dam removal can change landscape features of river and coasts, which have ecological implications downstream of former dam sites.
Robert Young: Seaward of Common Sense? SC Needs to Put an End to Building on the Beach
South Carolina’s beautiful beaches are a vital component of this state’s economy. Managing them wisely is critical to the health of the economy and to ensuring that state and local tax dollars are not wasted on futile efforts to protect homes needlessly placed in areas of obvious high hazard.
The Beach: a River of Sand

The tide may have brought in some new shells or possibly some trash, but the beach is the beach. It hasn’t gone anywhere. That is an illusion.
Row Erupts over Jamaica’s Bid to Slow Beach Erosion

Movement to Take Down Thousands of Dams Goes Mainstream
Twenty years ago, dam removal was a fringe notion, and early demolition efforts gained support only because the dams in question were no longer in use. Now, the U.S. dam removal movement has wide acceptance as well as bigger ambitions.
12 Dams that Changed the World
Renewable energy rather than mega dams and fossil fuels is the right choice for the 21st century. Even so, numerous destructive dams continue to be proposed and built on the Mekong, in the Amazon, throughout Africa, in China, the Himalayas and other parts of the world.
Progreso’s Prolonged Pier, Yucatan
The pier that extends from Progreso into the Gulf of Mexico is among the longest such structures in the world. Despite its arches, the structure as a whole has likely decreased the amount of sediment transported alongshore, leading to updrift accretion and downdraft erosion.
Erosion Creates Dangerous Situation on Waikiki Beach
Over the past several months severe erosion has caused a concrete slab near the water’s edge at Kuhio Beach to become exposed. Beach erosion in Waikiki has been a problem for decades and has resulted in at least 10 sand replenishment projects since 1939. 300,000 cubic yards of sand has been placed onto Waikiki Beach over the past 77 years.
