Deep water steepness (H sub 0/L sub 0) and beach slope (m) determine breaker type and breaker depth-to-height ratio. High initial H sub 0/L sub 0 induces breaking in deeper water since steepness grows faster than height. Slope determines the extent of nonlinear changes in wave shapes, which occur at a slow rate relative to wave speed. Slow shape changes accompanying soliton development significantly affect the breaking of oscillatory waves and provide plausible explanations for data on the breaking of solitary waves. An empirically and theoretically derived parameter of the form H/(sq m L sub 0) describes breaker type and predicts the transition between waves which reflect and waves which break on a beach.
