Through its Science Focus Area (SFA) projects the Subsurface and Biogeochemical Research program within the U.S. Department of Energy is tightly integrating observations, experiments, and modeling to advance a systems-level understanding of how watersheds function, and to translate that understanding into advanced science-based models of watershed systems. To broaden the impact of the existing SFAs, the IDEAS-Watersheds project builds on the success of a synergistic family of IDEAS projects initated in 2014. Specifically, it strives to improve wathershed modeling capacity by increasing software development productivity through an agile approach to creating a sustainable, reliable, parallel, software ecosystem with interoperable components.

In this talk we highlight the unique structure of the IDEAS-Watersheds project and describe how it addresses many challenges of software development with interdisciplinary teams. Specifically, it is organized around six Research Activities that develop concrete use cases to drive advances in our software ecosystem. These use cases are designed to balance advancing software design and development practices for parallel architectures with the model and algorithmic development needed to address scientific challenges. In addition, we use a co-funding model to create a team of early career researchers that will be trained in modern software engineering, while acting as liaisons that contribute to shared deliverables.
