SYMFLUENCE

SYnergistic Modelling Framework for Linking and Unifying Earth-system Nexii for Computational Exploration

---

Overview

SYMFLUENCE is a computational environmental modeling platform that streamlines the hydrological modeling workflow—from domain setup to evaluation. It provides an integrated framework for multi-model comparison, parameter optimization, and automated workflow management across spatial scales.

---

Installation

Environment setup varies by system.
Use the built-in installer whenever possible:

./symfluence --install

This creates a clean Python 3.11 virtual environment, installs dependencies, and registers local binaries.
For detailed instructions (ARC, FIR, Anvil, macOS), see INSTALL.md.

Quick Start

Basic CLI Usage

# Show options
./symfluence --help

# Run default workflow
./symfluence

# Run specific steps
./symfluence --setup_project --calibrate_model

# Define domain from pour point
./symfluence --pour_point 51.1722/-115.5717 --domain_def delineate

# Preview workflow
./symfluence --dry_run

First Project

cp 0_config_files/config_template.yaml my_project.yaml
./symfluence --config my_project.yaml --setup_project
./symfluence --config my_project.yaml

---

Python API

For programmatic control or integration:

from pathlib import Path
from SYMFLUENCE import SYMFLUENCE

cfg = Path('my_config.yaml')
symfluence = SYMFLUENCE(cfg)
symfluence.run_individual_steps(['setup_project', 'calibrate_model'])

---

Configuration

YAML configuration files define:

• Domain boundaries and discretization
• Model selection and parameters
• Optimization targets
• Output and visualization options

See 0_config_files/config_template.yaml for a full example.
