"CIROH DocuHub allows us at the University of Vermont's NETWA (Northeast Evaluation Testbed for Water Resources Applications) to effectively engage with our community by providing a listing of our services, documentation for how to use them, and an introductory "How to Get Started " page. It also allows us to share our progress and stay engaged with the broader CIROH community so that we can grow our impact as others discover and use our products and services."

"Having a community editable common place for sharing code, data resources, and community guidance was one of the critical first steps to being able to gather a community for operational hydrological modeling. CIROH DocuHub has begun to fill that gap. I am excited to see it growing and hope it becomes a valuable resource for the CIROH researchers and broader community."

"CIROH DocuHub has transformed my research process. I discovered several hydrological frameworks I wasn't previously aware of when searching for specific tools. The platform not only helps me learn from others' work, but also provides a professional space to document and publish my own research findings. When colleagues ask for my work, sharing a CIROH DocuHub link adds credibility and enhances collaboration. It's become an essential tool in my research workflow. "
