Ngen-DataStream

In the most important release yet, The NRDS system has successfully implemented GitHub Actions workflows to deploy the CFE NOM NextGen hydrologic simulation datastream using an automated pipeline. This new CI/CD capability has since allowed for the rapid deployment of three additional datastreams: the NWM->NextGen forcing processing, routing-only, and lstm_0 datastreams. These first datastream deployments demonstrates the uniquely powerful ability to modify and scale the NRDS numerical prediction system just through individual pull requests to this repository.
