Purdue University was awarded a $108,935 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to conduct collaborative research on climatic control of erosion rates and landscape morphology in Hawaii. The two-year award running from August 2023 to July 2025 will fund research quantifying the influence of fluvial thresholds on landscape response to climate change through study of evolving Hawaiian landforms. Key deliverables include field measurements, digital elevation model analyses, radiometric dating of lava flows, and estimates of catchment erosion rates using cosmogenic isotopes. The research aims to advance understanding of climatic control on landscape evolution and quantify how fluvial incision thresholds modulate connections between climate, topography, and erosion rates. As part of the award, Purdue will involve two undergraduate researchers from underrepresented Hawaii communities in project activities and conference attendance. Outreach efforts include educational activities at Purdue and the University of Indiana. All data generated will be publicly available.
