Maximum Runup Formula Elements

Variables
Wave Runup
Wave Runup is the maximum onshore elevation reached by waves, relative to the shoreline position in the absence of waves.
Symbol: R
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Deepwater Wave Height of Coast
Deepwater Wave Height of Coast refers to the measurement of the vertical distance between the trough and the crest of a wave in deep water.
Symbol: Hd'
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Deepwater Surf Similarity Parameter
Deepwater Surf Similarity Parameter compares the wave surface slope to the bed slope in the surf zone and represents important features of the hydrodynamics of the surf zone.
Symbol: ε0
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
