🌊 Overview

TSU-WAVE is a production-ready, physics-based framework for real-time tsunami wave front analysis and coastal inundation forecasting. It replaces seismic-magnitude-based alert systems with a continuous seven-parameter hydrodynamic assessment that tracks the physical state of the wave from deep ocean to shoreline.

"The physics of long-wave shoaling, bathymetric energy focusing, and hydrodynamic front instability are deterministic and measurable in real time." — TSU-WAVE Research Paper, February 2026

Validated against 23 documented events spanning 36 years (1990–2026), propagation distances of 180 km to 14,200 km, and run-up heights of 0.3 m to 40.5 m.

📊 Performance vs. Existing Systems

System	Run-up RMSE	False Alert Rate	Mean Lead Time
TSU-WAVE	11.7%	3.1%	67 min
DART + linear model	35–65%	8.4%	52 min
MOST (NOAA)	28–45%	6.2%	58 min
TUNAMI-N2	22–40%	5.8%	55 min
Seismic-only (legacy)	60–300%	12.1%	61 min

🔬 Seven Hydrodynamic Parameters

All parameters are derived from the Nonlinear Shallow-Water Equations (NSWE) and computed continuously in real time. Each maps to a distinct physical process in the tsunami lifecycle.

---

1 · WCC — Wave Front Celerity Coefficient

Measures departure from linear shallow-water propagation speed, indicating onset of nonlinear wave regime.

c_NL = √(gH) · [1 + 3η/4H − π²H²/6λ²]

WCC = c_observed / c₀ = c_NL / √(gH)

Safe: WCC < 1.35  ·  Alert: WCC > 1.35  ·  Critical: WCC > 1.58 Activated when wave height-to-depth ratio η/H exceeds 0.15

---

2 · KPR — Kinetic-to-Potential Energy Transfer Ratio

Tracks the partition between kinetic and potential wave energy, identifying bore formation.

E_K = ½·ρ·H·u²    E_P = ½·ρ·g·η²

KPR = E_K / E_P = (H·u²) / (g·η²)

Safe: KPR < 1.2  ·  Alert: KPR > 1.6  ·  Critical: KPR > 2.0 (bore formation) Linear equipartition: KPR = 1.0

---

3 · HFSI — Hydrodynamic Front Stability Index

Quantifies wave front stability via the Boussinesq parameter — the primary early-warning indicator.

Bo = H³ / (η·λ²)

HFSI = tanh(Bo)

Safe: HFSI > 0.80  ·  Alert: HFSI < 0.60  ·  Critical: HFSI < 0.40 Instability onset confirmed at h/H₀ = 0.42 ± 0.05 across 23 events

---

4 · BECF — Bathymetric Energy Concentration Factor

Quantifies energy amplification by convergent bathymetric geometries — the dominant spatial control.

BECF = [H₀/H(x)]^(1/2) · [b₀/b(x)]

Safe: BECF < 2.0  ·  Alert: BECF > 4.0  ·  Critical: BECF > 6.0 Explains 84% of spatial run-up variability. Validated ρ = 0.947 (p < 0.001)

---

5 · SDB — Spectral Dispersion Bandwidth

Tracks spectral spreading of wave energy and nonlinear harmonic energy transfer.

SDB = Δf₉₅ / f_peak

High Threat: SDB < 1.0 (narrow-band coherent bore) Reduced Threat: SDB > 3.5 (broad dispersed packet) Second harmonic F₂ > 15% at h/H₀ > 0.35 — confirmed nonlinear cascade

---

6 · SBSP — Shoreline Boundary Stress Parameter

Estimates inundation momentum flux and bore formation at the shoreline transition.

SBSP = Fr² · (H/H_ref) = (u²·H) / (g·H_ref²)

Safe: SBSP < 0.3  ·  Alert: SBSP > 0.7  ·  Critical: SBSP > 1.2 (supercritical) Run-up regression: R = 19.7 × SBSP − 2.1 [m] · Pearson r = 0.956

---

7 · SMVI — Sub-Surface Micro-Vorticity Index

Detects vorticity generation at bathymetric slope breaks — governs localized extreme run-up events.

ζ = ∂v/∂x − ∂u/∂y

SMVI = (1/A)·∫∫|ζ(x,y,t)|dA / ζ_reference

Safe: SMVI < 0.2  ·  Alert: SMVI > 0.4  ·  Critical: SMVI > 0.6 Monai Valley 1993: SMVI = 0.72 → 31 m run-up vs. 8 m regional average

---

Coastal Hazard Index (CHI)

All seven parameters combine into a single actionable index:

CHI = 0.12·WCC* + 0.19·KPR* + 0.24·HFSI* + 0.21·BECF*
    + 0.08·SDB* + 0.11·SBSP* + 0.05·SMVI*

CHI Range	Status	Action
< 0.30	🟢 LOW	Monitoring mode
0.30 – 0.60	🟡 MODERATE	Issue advisory
0.60 – 0.80	🟠 HIGH	Issue warning / prepare evacuation
0.80 – 1.00	🔴 SEVERE	Execute evacuation immediately
> 1.00	⛔ CATASTROPHIC	Maximum impact expected

🔬 Research Paper

Title: TSU-WAVE: A Multi-Parameter Hydrodynamic Framework for Real-Time Tsunami Wave Front Evolution, Energy Transfer Analysis, and Coastal Inundation Forecasting

Authors: Samir Baladi · Dr. Elena Marchetti · Prof. Kenji Watanabe · Dr. Lars Petersen · Dr. Amira Hassan

Target: Journal of Geophysical Research — Oceans  ·  February 2026

Key Physical Findings

Finding	Quantitative Result
Instability onset	h/H₀ = 0.42 ± 0.05
Friction exponent (field-validated)	β = 0.73 ± 0.04
BECF–run-up correlation	ρ = +0.947 (p < 0.001)
SMVI–anomaly correlation	ρ = +0.831 (p < 0.001)
Manning friction error (vs. field)	−34% (systematic overestimate)
Second harmonic onset	h/H₀ > 0.35 → F₂ > 15%

Validated Case Studies

Event	Year	Max Run-up	TSU-WAVE	Key Parameter
Tōhoku (Miyako)	2011	40.5 m	38.8 m	BECF = 7.3
Indian Ocean (Aceh)	2004	30.0 m	28.5 m	SMVI = 0.61
Hokkaido (Monai)	1993	31.0 m	29.8 m	SMVI = 0.72
