Surf and Coastal Area Measurement Platform (SCAMP) USACE Demonstration Survey Final Report

Abstract

Arete Associates, in accordance with contract DACW43-98-D-05191, and in cooperation with the US Army Corps of Engineers (USACE) New York District, conducted a hydrographic survey demonstration using a unique bathymetric system based on a jet ski with RTK GPS technology. This prototype system (designated SCAMP for Surf and Coastal Area Measurement Platform) had previously been developed using Aret internal R&D and Office of Naval Research funding. Informal testing in collaboration with the USACE Field Research Facility at Duck, NC showed that SCAMP provided 5 cm rms error in surf-zone and inlet operations. This report describes two USACE-specified modifications that were made to the SCAMP system prior to this demonstration: (1) a left/right indicator was mounted in view of the survey driver to assist the driver in navigating the designated survey line, and (2) the monitor-station software was modified to allow the option of re-designating the order in which survey lines are run. Both modifications were successfully installed and shown to be valuable survey assets during the demonstration. The SCAMP hydrographic system was shown to be an easily transportable, fast-response survey tool, which is suitable for shallow water beach and harbor operation. Also during this demonstration, the system was shown to be robust, performing well in moderate seas (1.2 m Hmo), and adaptable to adverse circumstances. However, the HYPACK data acquisition software developed to implement the two USACE-specified modifications produced data acquisition timing problems, the result of which was to de-correlate position and sounding measurements. After a significant post-test analysis effort, no means for correcting the data timing problems embedded in this data was identified. Thus, a comparison between the hydrographic survey data obtained by the USACE New York District and that obtained by SCAMP produced 12 to 22 cm rms error, rather than the previously experienced 5 cm rms error.
