    MEUFL (Cho, 2026; https://doi.org/10.1016/j.envsoft.2026.107045) is now available across multiple open-source software ecosystems: 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…

    After four years as CLAWRIM (Computational Lab for Advanced Water Resources Informatics and Modeling), our research group is being renamed to the HydroCS (Hydrologic Computational Science) Lab. The new name better reflects the evolution of our research program beyond water resources informatics and modeling. HydroCS emphasizes computational methods, scientific software, cyberinfrastructure, high-performance computing, and emerging…
