IIHR Activities

This initiative focuses on developing community codes and application portals based on extensive expertise in computational fluid dynamics (CFD) and river processes. Key projects include River3D and jANSWERS, which enhance watershed modeling and surface hydrology components. Recent accomplishments involve integrating subsurface flow models and atmospheric data, as well as performance testing and benchmarking with GRID technologies. Collaborations also lead to applications in flash flood analysis, leveraging high-resolution inputs to optimize flood evaluations.
