Automated system for continuous hydrologic predictions

• forcingprocessor - Forcingprocessor converts National Water Model (NWM) forcing data into Next Generation National Water Model (NextGen) forcing data
• ngen-datastream - Infrastructure and tooling for the NextGen Research DataStream (NRDS) - Datastream Orchestration on AWS
• datastreamcli - DataStreamCLI is a stand alone tool that automates the complete workflow from preprocessing input data for NextGen to execution of the NextGen simulation through NextGen In a Box (NGIAB)
• S3 bucket - datastream.ciroh.org - README.html provides more details
• NRDS Visualizer - nrds.ciroh.org
• Community parameter integration capability (in-progress)

Essential modeling engines powering the NextGen Water Resources Modeling Framework

• ngen - NextGen Water Resources Modeling Framework Engine (fork from NOAA-OWP repo) (ngiab branch integrated into NGIAB)
• t-route - Tree-based hydrologic routing engine for river network flow (fork from NOAA-OWP repo) (ngiab branch integreated into NGIAB)
• lstm - Basic Model Interface (BMI) for streamflow prediction using Long Short-Term Memory (LSTM) networks (main branch - integrated into NGIAB)
• rust-lstm - A Rust implementation of a BMI adapter for LSTM-based streamflow prediction

• api-nwm-gcp - NWM BigQuery API - REST API backed by National Water Model data, developed and deployed on Google Cloud Platform
• nwmurl - It provides utility functions specifically designed to subset and generate National Water Model (NWM) data URLs
• nwm_kerchunk - It provides National Water Model (NWM) output, which is stored as .nc files, into JSON headers and upload them to an AWS S3 bucket.

• awi-ciroh-image - CIROH JupyterHub Image repository

• ciroh-ua_website - technical documentation of few of the CIROH's projects, services, policies, latest blogs and news.
• ciroh-portal - CIROH portal for products, publications and courses
