Title: Experimental Use of the NextGen Water Resources Modeling Framework for Streamflow Prediction in Clear Creek, Colorado
Abstract: Recent efforts at NOAA-OWP and within the CIROH community have expanded to include the development of auxiliary resources to support the use of the Next Generation Water Resources Modeling Framework. Many of these data, tools, and workflows were first revealed at the CIROH Developers and Users Conference in May 2023 including, for example, NextGen in a Box. To date, however, there has been limited deployment of these capabilities, despite there being much to learn (for both developers and modelers) from experimental use. Here, we explore the deployment and use of the NextGen Framework for experimental streamflow modeling of Clear Creek near Golden, Colorado. We present the end-to-end development of multiple model formulations (including CFE and Noah-OWP-Modular), forced by the extended Analysis and Assimilation (AnA) forcings from the National Water Model. We demonstrate our streamflow simulation results and discuss the current technical challenges with using NextGen for real-time, over-the-loop forecasting. Lastly, we will highlight how the CIROH Hydrologic Prediction Testbed will be used for benchmarking and evaluating CIROH research efforts for objectives such as streamflow prediction.
