CUAHSI HydroShare is an open-source, web-based hydrologic information system designed to facilitate the sharing and publication of data, models, scripts, scientific workflows, and applications across the hydrologic science community. Adopted by the Cooperative Institute for Research to Operations in Hydrology (CIROH), HydroShare supports collaboration and open science practices in alignment with NOAA’s mandates for FAIR (Findable, Accessible, Interoperable, and Reusable) data and software. This presentation will showcase HydroShare’s capabilities for publishing water data and models, with a focus on enabling community research with the Next Generation (NextGen) National Water Modeling Framework on HydroShare-linked computing platforms. NextGen is a modular, interoperable hydrologic modeling system built on standardized interfaces such as the Basic Model Interface (BMI) and the Hy_Features data model developed by NOAA’s Office of Water Prediction. While powerful, NextGen’s complexity and supporting cyberinfrastructure pose significant barriers to broader research engagement. To address the challenges of engaging with NextGen’s complex modeling framework and cyberinfrastructure, CIROH has deployed tools within a cloud-based JupyterHub environment linked to HydroShare. This integrated platform streamlines the entire modeling workflow—from defining a spatial domain and time period, to generating input files, executing simulations, and analyzing outputs. Researchers can configure a research-scale instance of NextGen using a subset of NOAA’s standardized hydrofabric, which includes stream networks, catchments, and nexuses. Input data are drawn from NOAA’s Analysis of Record for Calibration (AORC), and model results can be compared with operational and retrospective outputs from the National Water Model, as well as ground-based observations, to support evaluation and improvement. Workflows and results are encapsulated in Jupyter Notebooks that can be executed to harness high-performance computing resources through cutting-edge cyberGIS capabilities and shared via HydroShare, promoting transparency, reproducibility, and accessibility. By linking research products to a computational environment capable of executing them in a scalable fashion, this approach enables documented workflows to be shared alongside the associated data and models. These capabilities lower technical barriers, expand community engagement with NextGen, and foster collaborative hydrologic research. They also serve as an entry point for advancing the National Water Model as it transitions to the NextGen framework. We will reflect on the generalizability of these strategies, the challenges encountered, and lessons learned from applying HydroShare within CIROH and NextGen. The presentation will also explore how these practices can be extended to other domains within the atmospheric and ocean sciences, advancing open, transparent, and efficient research and operations.
