# Hydraulic Engine

A Python package for managing hydraulic calculation actions: EPANET/SWMM simulations, RPT file imports, and more.

## Features

- **Run SWMM simulations**: Execute Storm Water Management Model simulations
- **Run EPANET simulations**: Execute water distribution network simulations
- **Parse INP files**: Read and modify SWMM/EPANET input files
- **Parse RPT files**: Read and analyze simulation results
- **Multiple database support**: PostgreSQL (psycopg3), SQLite, and GeoPackage

## Installation

### From PyPI

```bash
pip install hydraulic-engine
```

### From source

```bash
git clone https://github.com/bgeo-gis/hydraulic-engine.git
cd hydraulic-engine
pip install -e .
```

### Development installation

```bash
pip install -e ".[dev]"
```

## Quick Start

### Running a SWMM Simulation

```python
import hydraulic_engine as he

# Create runner
runner = he.SwmmRunner(inp_path="drainage_model.inp")

# Run simulation
result = runner.run()

# Check results
if result.status.value == "success":
    print(f"Simulation completed in {result.duration_seconds:.2f}s")
    print(f"RPT file: {result.rpt_path}")
else:
    print(f"Errors: {result.errors}")
```

### Running an EPANET Simulation

```python
import hydraulic_engine as he

# Create runner
runner = he.EpanetRunner(inp_path="water_network.inp")

# Run simulation
result = runner.run()

# Check results
if result.status.value == "success":
    print(f"Simulation completed in {result.duration_seconds:.2f}s")
```

### Reading SWMM INP Files

```python
import hydraulic_engine as he

# Create handler
handler = he.SwmmInpHandler()

# Read INP file
if handler.read("model.inp"):
    # Get model summary
    summary = handler.get_summary()
    print(f"Junctions: {summary['counts']['junctions']}")
    print(f"Conduits: {summary['counts']['conduits']}")

    # Get specific sections
    junctions = handler.get_junctions()
    conduits = handler.get_conduits()

    # Modify and save
    handler.write("modified_model.inp")
```

### Reading SWMM Results

```python
import hydraulic_engine as he

# Create handler
handler = he.SwmmRptHandler()

# Read RPT file
if handler.load_result("results.rpt"):
    # Get results
    node_depths = handler.get_node_depth_summary()
    link_flows = handler.get_link_flow_summary()
```

### Validating INP Files

```python
import hydraulic_engine as he

# Validate without running
runner = he.SwmmRunner()
validation = runner.validate_inp("model.inp")

if validation["valid"]:
    print(f"Model info: {validation['info']}")
else:
    print(f"Validation errors: {validation['errors']}")
```

### Progress Tracking

```python
import hydraulic_engine as he

def on_progress(progress: int, message: str):
    print(f"[{progress}%] {message}")

runner = he.SwmmRunner(progress_callback=on_progress)
result = runner.run("model.inp")
```

## Database Connection

The package supports database connections for storing/retrieving model data.

### PostgreSQL Connection

```python
import hydraulic_engine as he

# Create connection (becomes the default)
conn = he.create_pg_connection(
    host="localhost",
    port=5432,
    dbname="hydraulic_db",
    user="user",
    password="pass",
    schema="my_schema"
)

# Use connection
rows = conn.get_rows("SELECT * FROM nodes")

# Close when done
he.close_connection()
```

### GeoPackage Connection

```python
import hydraulic_engine as he

# Create connection
conn = he.create_gpkg_connection("project.gpkg")

# Query data
rows = conn.get_rows("SELECT * FROM conduits")

# Close when done
he.close_connection()
```
