Decadal Data Set of Hourly Beach Profile Evolution in Duck, NC
摘要
This paper presents initial results of a decadal dataset of sub-aerial beach profile evolution collected at the U.S. Army Engineer Research and Development Center’s Field Research Facility in Duck, NC using a stationary terrestrial lidar scanner (TLS) mounted above the dune. The data are processed using an automated work flow in near realtime and are made public for the coastal science and engineering community to use at ( https://chlthredds.erdc.dren.mil/ ). At submission, the data set consisted of 48,911 processed cross-shore profiles that passed the automated quality assurance quality control checks (81% of the 60,6046 collected scans). A basic description of the dataset is provided, including example storm impact and beach recovery sequences, and an initial investigation is presented that relates pre-storm beach morphology, storm wave power, and profile response and highlights the importance of initial beach state.
