Abstract
The Interoperable Design of Extreme-scale Application Software—Watersheds (IDEAS-Watersheds) project is designed to enhance and broaden the impact of the existing watershed Science Focus Areas (SFAs) within the ESS program through an agile approach to creating a sustainable and reliable software ecosystem.
This poster highlights the unique structure of the IDEAS-Watersheds (Phase 2) project, which is organized around three research activities and four shared infrastructure activities. To ensure integration of the research activities with the SFAs and facilitate training of early career researchers, the team uses a co-funding model with shared deliverables to establish partnerships. These partnerships increasingly embrace a multiscale perspective of the whole watershed and include the Watershed Function SFA (see Lawrence Berkeley National Laboratory-SLAC poster by Molins et al.), the Watershed Dynamics and Evolution SFA (see Oak Ridge National Laboratory poster by Painter et al.), and the River Corridor SFA (see Pacific Northwest National Laboratory poster by Chen et al.). Each research activity is focused through the design of concrete use cases that both advance scientific understanding as well as contribute transferable capabilities to the software ecosystem.
The shared infrastructure activities provide foundational support for the research activities as well as training and community outreach. The Software Stewards activity will ensure the sustainability of the software ecosystem as a community resource and make it more reliable, accessible, and easier to use. The Land Model Interface Activity addresses the critical need for best practices in model setup and analysis of integrated hydroterrestrial models that couple integrated hydrology and land surface models. An Integrated Hydrology Simulation Infrastructure Activity will continue the development of a national hydrology infrastructure that can accelerate regional simulations and improve modeling workflows across modeling platforms. Finally, the team will continue building a community around the software ecosystem through a Training, Community Building, and Outreach Activity.
