dc.descriptionSpecial Report
dc.description.abstractThis report summarizes 44 years of beach-nearshore profile survey data collected at the Field Research Facility (FRF). The FRF is operated by the Coastal Observations and Analysis Branch of the Coastal and Hydraulics Laboratory, one of the laboratories of the U.S. Army Engineer Research and Development Center. The 1,110 surveys collected between 1974 and 2018 provide a unique temporal and spatial record of beach and nearshore change under a wide variety of conditions (waves, tides, currents, etc.) that have been monitored by the FRF data collection program. Over the years, the collection methods evolved from manually reading and recording each survey position to continuously recording Global Positioning System observations. Each method is presented along with its strengths, weaknesses, accuracy, and error sources. As the equipment has changed, the consistency and overall accuracy has improved. The intent of this report is to document the FRF survey program as a guide for future data collectors and users of these data.en_US
