The National Science Foundation (NSF) Geosciences program awarded a $498,356 project grant to the University of Nevada, Reno (UNR) for the project "Controls on Ridgeline Profile Morphology." This 3-year grant, effective July 1, 2024, will fund research to improve the understanding of how ridgelines are shaped and eroded, which is key to predicting natural hazards like landslides, debris flows, and river flooding. The project will test three hypotheses about the controls on ridgeline...
This five-year, $475,451 National Science Foundation project grant in the Geosciences program (CFDA 47.050) will support research examining how topography preserves details of the seismic cycle. The principal investigator will develop computational landscape simulations under varying tectonic and climatic conditions to identify topographic signatures of the seismic cycle. They will then assess whether these signatures are recognizable in natural landscapes with independent constraints on seismic...
The National Science Foundation awarded a three-year $336,534 Project Grant to the University of Colorado Boulder under the Geosciences program (CFDA 47.050) to support collaborative research on the role of extreme rainstorms and hydroclimatic regimes on arid escarpment retreat and sub-cliff slope evolution. The research funded through this award will strengthen understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences as outlined under...
This three-year, $334,539 National Science Foundation project grant supports collaborative research between Colorado State University and the University of Puerto Rico at Mayagüez to test critical zone controls on mountain-scale relief in Puerto Rico's tropical climate. The research will examine how differences in critical zone processes influence topography through a comparative study of volcanic and granitic bedrock units on the island. The project will evaluate the impact of soil and...
The National Science Foundation awarded a $174,000 project grant under the Geosciences program (CFDA 47.050) to support research titled "UNRAVELING FLUVIAL KINEMATICS BEFORE THE RISE OF LAND PLANTS: BRIDGING LABORATORY AND GEOLOGIC SCALES." The two-year award beginning August 1, 2021 will fund basic research at the University of California, Santa Barbara to enhance understanding of the integrated Earth system through expanded knowledge of atmospheric, earth, and ocean sciences....
This $237,361 federal Project Grant awarded by the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) supports collaborative research to advance predictive understanding of landscape evolution and erosion dynamics under changing climate conditions. The key research objectives are to: 1) Extract local geomorphic transport laws driving landscape evolution under different climatic forcings using large-scale experimental data and novel physics-informed AI methods; 2) Quantify...
This National Science Foundation Project Grant of $142,251 supports research examining the influence of critical zone processes on topography in Puerto Rico. Funded under the Integrative Activities program, the award will test hypotheses about how differences in bedrock geology and associated soil characteristics impact landslide occurrence, sediment grain sizes in rivers, and flood frequencies. Researchers from the University of Puerto Rico Mayagüez and Colorado State University will conduct...
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), aims to unveil the role of hillslope hydrology in mediating ecosystem response to drought. The primary research objectives are to understand how trees may slow their growth or die during drought and the importance of access to deep water, depending on the landscape position. The $290,728 award, with a project period from July 1, 2025 to June 30, 2030, will utilize various tools, including...
This $329,667 federal Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research to develop and test a new model for predicting sediment creep under the influence of groundwater flow. The principal investigators, based at Clark University and the Naval Postgraduate School, will conduct laboratory experiments and field surveys to quantify sediment creep mechanics, then implement the new sediment creep function in an open-source...
This National Science Foundation Project Grant of $590,428 will fund research at Utah State University from July 2022 to June 2025 to develop a physical model characterizing the response of mountain river channels to climate change perturbations. The research aims to separate river response signals from inherent natural variability through three components: establishing a baseline variability model using high-resolution topography and sediment data; developing a physical linkage between...
