Abstract : Observations of sand levels at pipes placed at 50-foot intervals from dune to low tide terrace along two profile lines on each of five Atlantic Coast Beaches proved to be a feasible alternate method of surveying beach profiles. For 1-week intervals during January, February, and March 1968, the maximum changes in sand level at any pipe on the five beaches was 5.7 feet of erosion and 4.7 feet of accretion. Changes in sand level were more likely at pipes located in the beach face than at pipes located below mean sea level. When significant erosion occurred between successive surveys on any profile, there was a tendency for the maximum decrease in sand level to occur at locations high on the earlier of the two surveys. Pipe-profile data showed that beach steepness and fluctuations in sand level usually decrease in a north-to-south direction for the five beaches studied. (Author)
