A useful description of a linear wave field is obtained by the measurement of the frequency-directional spectrum. Particular attention is paid to certain momen

Santa Barbara and Rudee Inlet Experiments could not be employed since it requires a constant relationship between wave numbers and frequencies along its length. Further, the contours suggest a significant longshore variation in the incident wave field. Two compact arrays were selected as the measurement scheme to provide some capability to

Methods for Position Control and Beach Face Profiling as part of Task 4E of the Nearshore Sediment Transport Study (NSTS). This surveying was used to measure changes in beach shape and volume caused by cross-shore and longshore sediment transport during the inter-survey periods. The surveys also provided a daily measurement of the height of surf zone

Offshore Surveyss to determine sediment volumes in water depths too great for standard rod and level surveying procedures employed on the dry beach or in wading depths. Soundings are subject to particular types of errors which can lead to bias in the results and substantially misleading volume errors. These errors

Measurement Errors for Electromagnetic Current Metersts in the surf zone, for modeling of both hydrodynamics and sediment transport. These meters were chosen because of their history of successful use in previous surf zone studies, relying on their compactness and durability in this rough environment. The present work was motivated by examination of t
