## Overview

iHydroCal provides a unified framework for calibration and uncertainty analysis of integrated hydrological models including:

- SWAT (Soil and Water Assessment Tool)
- SWAT+ (SWAT Plus)
- SWAT-MODFLOW (coupled surface-groundwater model)
- APEX-MODFLOW-RT3D-Salt (integrated modeling system)

## Features

- 🎯 **Unified Calibration Framework**: Single interface for multiple model types
- 📊 **Uncertainty Analysis**: Comprehensive sensitivity and uncertainty quantification
- 🔧 **PEST++ Integration**: Leverage industry-standard optimization tools
- 🐍 **Python-Based**: Built on pyemu and flopy
- 📈 **Visualization**: Built-in plotting and reporting capabilities

## Installation

### From PyPI (coming soon)
```bash
pip install ihydrocal
```

### From conda (coming soon)
```bash
conda install -c conda-forge ihydrocal
```

### Development Installation
```bash
git clone https://github.com/yourusername/ihydrocal.git
cd ihydrocal
pip install -e .[dev]
```

## Quick Start
```python
import ihydrocal as ihc

# Load configuration
config = ihc.load_config("config.yaml")

# Initialize model
model = ihc.create_model("swat-modflow", config)

# Run calibration
calibrator = ihc.Calibrator(model, config.calibration)
results = calibrator.run()

# Uncertainty analysis
uncertainty = ihc.UncertaintyAnalysis(model, results)
uncertainty.sensitivity_analysis()
```
