Hydraulic Parameters of Overtopping Wave Volumes
Publication: Coastal Structures and Solutions to Coastal Disasters 2015: Resilient Coastal Communities
ABSTRACT
Wave overtopping measurements acquired during the FlowDike small-scale physical model tests were analyzed to extract information related to individual overtopping waves. Individual overtopping wave volumes and associated hydraulic parameters were determined at the seaward edge of the model dike crest for normally-incident wave conditions impinging on either a 1V:3H or 1V:6H planar seaward-side dike slope. A two-step “supervised” procedure was used that combined the best features of automated wave volume determination along with manual error correction. This resulted in a well-vetted data set consisting of 5,799 individual overtopping wave volumes. New empirical relationships are presented for the maximum velocity, maximum flow thickness, maximum instantaneous discharge per unit crest length, and overtopping duration as functions of individual wave volume, and in some cases, mean spectral wave period.
