HydroNet: Network-Based Early Warning System for Hydrological Collapse

📋 Overview

HydroNet is an early warning system for hydrological collapse based on multi-domain network analysis using 12 key indicators across climatic, hydrological, infrastructural, and socioeconomic domains. The system provides early warnings with a median lead time of 8.4 months before conventional indicators signal emergency.

🚀 Quick Start

📊 Core Package Usage

A. Basic Prediction Example

import numpy as np
from Core_Package.hydronet.extended.predictor import HydroPredictor

# Create sample data
data = {
    "precipitation": np.random.normal(0, 1, 100),
    "streamflow": np.random.normal(0, 1, 100),
    "groundwater_levels": np.random.normal(0, 1, 100),
    # ... add all 12 indicators
}

# Predict collapse risk
predictor = HydroPredictor(threshold=0.6)
result = predictor.predict_collapse_risk(data)

print(f"System Vulnerability Index: {result['svi']:.3f}")
print(f"Risk Level: {result['risk_level']}")
print(f"Warning: {result['warning']}")

B. Real-Time Monitoring

from Core_Package.hydronet.extended.monitor import HydroMonitor

# Start monitoring a basin
monitor = HydroMonitor(
    basin_name="Colorado River Basin",
    update_interval=3600  # seconds
)

# Run monitoring for 24 hours
monitor.run_monitoring(hours=24)

# Generate report
report = monitor.generate_report()
print(report)

📈 The 12 Network Indicators

1. Climatic Domain: · Precipitation · Evapotranspiration · Atmospheric Pressure
2. Surface Water Domain: · Streamflow · Lake Levels · Reservoir Storage
3. Groundwater Domain: · Groundwater Levels · Groundwater Quality
4. Soil & Land Domain: · Soil Moisture · Land Subsidence
5. Human Impact Domain: · Water Extraction · Land Use Change

🔍 Interpreting Results

System Vulnerability Index (SVI)

· 0.0 - 0.4: Low risk · 0.4 - 0.6: Medium risk · 0.6 - 0.8: High risk · 0.8 - 1.0: Critical (requires immediate intervention)

Alert Levels

· LOW: System stable · HIGH: Increased monitoring needed · CRITICAL: Immediate intervention required

🎯 Use Cases

1. For Researchers

# Analyze historical data
from Core_Package.hydronet.extended.hydro_metrics import HydroMetrics

metrics = HydroMetrics()
network_density = metrics.network_density(adjacency_matrix)
transfer_entropy = metrics.transfer_entropy(source_data, target_data)

2. For Water Managers

# Monitor multiple basins
python CLI_Tools/basin_monitor.py --basins "Nile,Colorado,Indus"

3. For Developers

# Develop new features
git checkout -b feature/new-algorithm
# After development
make test-all  # Ensure all tests pass

📞 Support & Troubleshooting

Common Issues

# Issue: Circular import
# Solution: Reinstall requirements and run make clean

# Issue: Insufficient data
# Solution: Each indicator needs at least 30 data points
