Hy²DL: Hydrological modeling using Deep Learning methods

Hy²DL is a python library to create hydrological models for rainfall-runoff prediction using deep learning methods. The repository includes implementations with Large-Sample Hydrology datasets such as CAMELS-GB, CAMELS-US, CAMELS-DE, CAMELS-CH and CARAVAN.

The folder structure and some of the code logic presented here is based on NeuralHydrology.

Structure of the repository:

The codes presented in the repository are in the form of python scripts. Additionally several experiments are in the form of JupyterNotebooks for easy reproduction and execution. Following is a quick overview of the repository structure:

• benchmarks: Comparison of our library against other studies from scientific literature.
• data: Folder where the different datasets (e.g CAMELS-GB, CAMELS-US...) should be added. This information should be independently downloaded by the user.
• docs: Library documentation
• examples: Codes (.py) and configuration files to run multiple examples.
• notebooks: Jupyter notebooks showing implementation examples, for different cases.
• results: Folder where the results generated by the codes will be stored.
• src/hy2dl: Code of the library.

Documentation:

Detailed documentation for the repository can be found at Hy2DL.readthedocs.io.

Installation

A release version is available on PyPI and can be installed using:

uv
