Maximum wave runup on smooth impermeable plane slopeSummary of Irregular Wave Runup Prediction for Smooth Slopes: Hughes (b)recommended the following equations for prediction of irregular wave runup on smooth,impermeable slopes for nonbreaking (surging/collapsing) waves and breaking (plunging/spilling)waves as delineated by values of .

Knowledge on wave-runup levels is important for a proper design of the crest height of coastal structures. An overall view of the literature supports the assertion that smooth slopes cause the. Special cases where runup occurs on steep slopes and where runup exceeds barrier or bluff crests. are discussed. Guidance for mapping flood hazards based on runup and overtopping values is. given. D Wave Runup D Overview. Wave runup is the uprush of water from wave action on a shore barrier intercepting stillwater level. WAVE RUNUP AND OVERTOPPING 2 FEMA COASTAL FLOOD HAZARD ANALYSIS AND MAPPING GUIDELINES FOCUSED STUDY REPORTS As used in this report, wave overtopping refers to the volumetric rate at which runup flows over the top or crest of a slope, be it a beach, dune, or structure. This report provides recommendations for: development of wave runup and . The Coastal and Hydraulics Engineering Technical Note (CHETN) described herein provides a new formula for estimation of irregular wave runup on rough, .

Field Measurements of Wave Runup. Wave runup was measured in the field to determine the appropriate wave runup equations to be used for the study sites. Video cameras were used to record 60 minute segments of wave runup at most of the study sites. For calm conditions a line of stakes was set up at a known interval (see figure below). A method of estimating wave runups on plane, smooth slopes is presented. The method uses empirical formulas to predict monochromatic wave runups for a wide range of surf conditions. Intuitive arguments are used to support the form of the equations. Then, available data of runup on smooth and rock slopes are compared. The main part of this paper deals with runup on rock slopes, including revetments and breakwater structures. The slopes range from to About tests have been performed, testing stability of armor layers, during which runup was simultaneously measured. The relative wave runup decreases with increasing wave steepness especially in smooth and rough impermeable models according to Shankar and Jayaratne. The most widely used method to predict the wave runup is the regression method (RM) developed by Van der Meer et al. [3], used to predict runup on rock armoured by: 2.
