Hydrologic modeling can help us understand how to better respond to extreme hydrologic events. Communicating model results to different groups has been a recurring challenge due to the evolving nature of hydrologic models and the distinct needs of different groups. A new National Water Model (NWM) was released in 2016 by NOAA’s Office of Water Prediction (OWP) that generates forecasts for multiple variables at a national scale. The large amounts of data produced by the NWM presents new challenges in water data management. The Open Water Data Initiative (OWDI) was started in 2014 with the goal of standardizing and facilitating water data integration and sharing. Following the conceptual model described in the OWDI, we have created a cyberinfrastructure to store NWM results, and created two web applications deployed on the HydroShare Tethys Portal to facilitate access by interested community users. A REST API was also developed in accordance with the OWDI requirements to provide water data as a service. This API facilitates programmatic data retrieval and integration of our tools with third-party projects. The developed cyberinfrastructure, web apps, and REST API provide a gateway for NWM results to be effectively communicated to scientists, planners, emergency responders, and the general public by meeting their specific needs.
