## 🌊 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` &nbsp;·&nbsp; **Alert:** WCC > `1.35` &nbsp;·&nbsp; **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` &nbsp;·&nbsp; **Alert:** KPR > `1.6` &nbsp;·&nbsp; **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` &nbsp;·&nbsp; **Alert:** HFSI < `0.60` &nbsp;·&nbsp; **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` &nbsp;·&nbsp; **Alert:** BECF > `4.0` &nbsp;·&nbsp; **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` &nbsp;·&nbsp; **Alert:** SBSP > `0.7` &nbsp;·&nbsp; **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` &nbsp;·&nbsp; **Alert:** SMVI > `0.4` &nbsp;·&nbsp; **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 |

```

### Clone & Run

```bash
# Clone from GitLab (primary)
git clone https://gitlab.com/gitdeeper4/tsu-wave.git
cd tsu-wave

# Create virtual environment
python3 -m venv venv && source venv/bin/activate

## 🔧 Usage

### Python API

```python
from tsuwave import TSUWave
from tsuwave.parameters import CHI
from tsuwave.data import DARTStream

# Initialize system
tsw = TSUWave.from_config("config/config.yml")

# Start real-time parameter computation
await tsw.start()

# Access current Coastal Hazard Index for a coastal zone
chi = await tsw.get_chi(zone="hilo_bay_hawaii")
print(f"CHI: {chi.value:.3f} — Status: {chi.status}")
# CHI: 0.724 — Status: HIGH

# Get all seven parameters
params = await tsw.get_parameters(zone="hilo_bay_hawaii")
print(params)
# WCC:  1.31  MONITOR
# KPR:  1.44  MONITOR
# HFSI: 0.63  ALERT
# BECF: 4.80  ALERT
# SDB:  1.20  MODERATE
# SBSP: 0.67  ALERT
# SMVI: 0.29  MONITOR
```

### Command Line

```bash
# Monitor active events
tsu-wave monitor --live

# Compute CHI for specific coastal zone
tsu-wave chi --zone hilo_bay --event active

# Run-up forecast
tsu-wave forecast --zone khao_lak --source sumatra

# Validate against historical event
tsu-wave validate --event tohoku_2011

# Generate operational report
tsu-wave report --event tohoku_2011 --format pdf

# System status
tsu-wave status --all
```

## 🔬 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 &nbsp;·&nbsp; 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 |
