Title: HydroShare and CIROH Computing, Lowering the Barriers to Data Access and Modeling
Presentation Type: Poster Presentation
Abstract: This project leverages the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) HydroShare platform to enhance research collaboration by providing a cloud-based environment for hydrologic data access, modeling, analysis, and sharing within the Cooperative Institute for Research to Operations in Hydrology (CIROH) community. We developed Jupyter Notebooks that enable users to retrieve and subset the National Oceanic and Atmospheric Administration (NOAA) Analysis of Record for Calibration (AORC) dataset for specific points or watershed areas from both geographic and National Water Model (NWM)-projected grids. These tools are integrated with CIROH 2i2c-JupyterHub, allowing users to execute workflows without local software installation. In addition, we developed the CIROH Community NextGen Hub (CCNH), which provides a preconfigured environment for Next Generation Water Modeling Framework (NextGen) setup, calibration, and evaluation using tools such as Tools for Exploratory Evaluation in Hydrologic Research (TEEHR). This approach reduces technical barriers, supports reproducibility, and enables collaborative hydrologic modeling for operational water prediction.
