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 substitute method of surveying beach profiles. For I-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 (from Westhampton Beach, N. Y., through Ludlam Island, N. J.), in a way that appears related to decreases in wave height and the sediment size on the same beaches. Five appendixes to this paper contain the pipe profile data obtained during the 1968-69 winter, both in tables and in four types of graphs. A sixth appendix contains the daily visual wave observations obtained at seven Atlantic Coast beaches, including the five beaches with pipe profiles, during the same time.
