Design of Regional Wave Monitoring Networks: A Case Study for the Southern California Bight

Fundamental considerations in designing wave gauging networks, and an objective method for selecting optimal gauge locations for monitoring coastal wave conditions, are described. The focus is on the spatial variation of wave conditions owing to propagation across the continental shelf and near coastal bathymetry. Generation by local winds and dissipation within the surf zone are not included, so this preliminary work concerns nonbreaking, low-frequency swell waves. Application of the regional network design method is illustrated with an ongoing case study in the Southern California Bight, and the relevance of this work to other sections of the U.S. coastline is discussed. Recommendations for future studies, aimed at efficiently expanding the spatial coverage and, hence, utility of the present Field Wave Gauging Program are presented.
