Beach Nourishment

Sediment being pumped onto Figure Eight Island, North Carolina. View Beach Nourishment Gallery

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.

The Army Corps of Engineers Moves Forward With 50-Year Project

After more than a decade of work and research, a project report that aims to keep Bogue Banks beaches nourished for the next five decades has been submitted for final comment. The estimated cost for the initial project construction and the reoccurring nourishment projects over the next 50 years is $266,783,000. Since 2001, the project cost the county $2,947,503.

Endless Erosion Battle a Matter of Money

Since the first federal beach renourishment project in 1969, 3 million cubic yards of sand have been pumped back onto the beach, and about $25 million in today’s dollars have been spent on Treasure Island, Florida, alone to fight a natural process that’s been happening for ages on barrier islands, researchers say.

Along Jersey Shore, Towns Build Sandcastle Dunes

The hills of sand are supposed to act as fortresses that protect Jersey Shore communities from the ravages of the sea. But unless the sand can be stabilized by vegetation, one municipal engineer said, “They disappear like children’s sand castles at the end of the day.”

The Fickleness of Sand

Beach sand is a fickle thing. It gets pushed around by winds and waves, and you can never tell with any certainty where it will end up, despite the best engineering and intentions.

Computer Model to Help Managers with Renourishment Decisions?

Since the first project of its kind in the U.S. at Coney Island, N.Y., in 1922, coastal managers have used beach nourishment – essentially importing sand to replace sediment lost through storms or erosion – to restore damaged beaches, but it is laborious and expensive.
