MEUFL (Cho, 2026; https://doi.org/10.1016/j.envsoft.2026.107045) is now available across multiple open-source software ecosystems:
- MIDAS C library: https://github.com/HuidaeCho/midas
- Standalone executable: https://github.com/HuidaeCho/meufl
- GRASS addon r.upflowlength: https://grass.osgeo.org/grass-stable/manuals/addons/r.upflowlength.html
- Python package midasflow: https://pypi.org/project/midasflow/
- R package midasflow: https://github.com/HuidaeCho/midasflow-r
- QGIS plugin MIDAS: https://plugins.qgis.org/plugins/midas/
Currently, the Python, R, and QGIS interfaces depend on the MIDAS C library.
MEUFL is a memory-efficient upstream flow length HPC algorithm, designed for large-scale hydrologic and flow-network analysis.
Making new algorithms accessible across open-source software ecosystems is an important part of translating hydrology research into practice.
