Iribarren Surf Similarity Runup Regime Classifier
Deep-water Iribarren number ξ = tanβ/√(H/L₀) and the conventional spilling, plunging, or surging breaker classification.
Description
Deep-water Iribarren number ξ = tanβ/√(H/L₀) and the conventional spilling, plunging, or surging breaker classification.
Iribarren Surf Similarity Runup Regime Classifier is a focused tool for the following task. Deep-water Iribarren number ξ = tanβ/√(H/L₀) and the conventional spilling, plunging, or surging breaker classification. It reports ξ, Regime from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Iribarren Surf Similarity Runup Regime Classifier
Use this seismology calculation to reproduce a stated convention, screen observations, or compare scenarios whose units, coordinate conventions, catalog selection, and model assumptions are known.
- tanβ
- Required number. Beach slope.
- H (m)
- Required number in m. Offshore wave height.
- T (s)
- Required number in s. Wave period.

How Iribarren Surf Similarity Runup Regime Classifier works
Deep-water Iribarren number ξ = tanβ/√(H/L₀) and the conventional spilling, plunging, or surging breaker classification. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- ξ
- Returned number. Surf similarity parameter.
- Regime
- Returned string. Spilling, plunging, or surging.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- tanβ must be at least 0.
- H must be at least 0.
- T must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
