Kinematics of a Focused Wave Group on a Plane Beach: Physical Modeling in the UK Coastal Research Facility

This paper presents results of surface elevation and kinematics measurements made in the UK Coastal Research Facility (UKCRF). Investigations were made into the behavior of focused wave groups as they ran up and overtopped a plane beach and a sea wall. Measurements of the kinematics of focused wave groups were made using an acoustic Doppler velocimeter (ADV) and a laser Doppler anemometer (LDA). Kinematics results from the LDA alone are presented in this paper. Analysis of the data has revealed information about the harmonic structure of the wave group both for surface elevation and kinematics.
