Beach Nourishment
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.
