Beach Nourishment

If we must nourish beaches, we should use the least damaging source areas for sand and regulations/laws to that effect are needed. In addition, there is a global sand quality problem – poor quality (gravelly, muddy, shelly sand) is being pumped up on beaches (North Carolina, USA, and southern Spain). Recognition of the biological impact of placing sand on a beach is a particularly great need as beach nourishment temporarily destroys the entire nearshore marine ecosystem affecting birds, nearshore fish, and invertebrates. Source areas for sand are sometimes problematic as was the case in 2007. The US Army Corps of Engineers used off-shore sand from a former dump site from WW II resulting in the deposition of sand on a New Jersey beach along with 700 live rounds of munitions. Fortunately, no one was injured, but vacationers digging in the sand found the munitions. Dubai poses different challenges – fine sediment from the dredging operations there has done permanent damage to the coral reefs and ecosystem. Active coral reefs were buried when artificial islands were created after 2000.

Shifting sand differs on developed, undeveloped beaches; Georgia

Natural and undeveloped beaches should not be armored or modified with “nourishment,” as the sand-sharing system moves deposits from dune to beach in storms and back again. Normally following storms, beach sands are gradually returned to reform dunes.

Study: Sand nourishment linked to fewer marine life

UC San Diego biologists who examined the biological impact of replenishing eroded beaches with offshore sand found that such beach replenishment efforts could have long-term negative impacts on coastal ecosystems.

Hawaii bill to restore Waikiki Beach

Despite being one of Hawaii’s most iconic beaches, many visitors don’t know Waikiki Beach is actually an engineered beach that has been filled with imported sand. Waikiki has been facing erosion problems for years, and Hawaii lawmakers are pushing a bill to restore it…again. The state estimates that approximately 300,000 cubic yards of sand have been imported to Waikiki beaches over the past 75 years, often mined from other beaches in the state.

Is there enough sand to go around?

The sand we spread our towels on in visits to the Delaware beach towns was once at the bottom of the sea, before engineers pumped it onto the shoreline in a wave of beach replenishment projects.

Fairhope continues to fight beach erosion, AL

After a major beach replenishment effort in 2014, the city of Fairhope continues to fight erosion problems. The beach near the Pier Street boat ramp is losing about 10 percent of its sand each year. For the second year in a row, tons of sand have been lost at the public beach south of Pier Street. It’s an ongoing battle with Mother Nature.

Beach work: The billion-dollar question for New Jersey

December 26th, 2015

Restoring eroded beaches was a billion-dollar problem in New Jersey even before Sandy. Towns have added sand to beaches for generations, yet sand drifts. So if a town manages to keep a beach in place on one block, chances are the beach on another block will erode twice as quickly.

Save beach from renourishment

December 12th, 2015

If we really value our beach and what it means to our economy, we should do more to protect it. With so-called beach renourishment (pumping offshore sand onto beach for protection) and the current Coastal Construction Line (development setback line), we are just toying with protection.
