The grantee will develop and validate...

This $394,302 National Science Foundation project grant supports research at Purdue University to advance understanding and modeling of seismic cracking in earthen embankments and dams. Funded through the Engineering program (CFDA 47.041), the two-year Boosting Research Ideas for Transformative and Equitable Advances in Engineering Synergy project aims to validate assumptions around using static analyses to estimate earthquake-induced cracking location and size. Researchers will combine case...

The National Science Foundation awarded a $796,676 project grant to the University of Maryland, College Park to support research investigating the mechanisms enabling high pore fluid pressure to facilitate slow faulting. Funded through the Geosciences program (CFDA 47.050), the three-year award will advance understanding of the role elevated fluid pressures play in stabilizing fault propagation and decelerating frictional slip along pre-existing faults. Researchers will conduct fracture and...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) totaling $225,816 will support collaborative research to investigate the evolution of elastic wave properties during the seismic cycle. The primary objectives are to explore whether variations in seismic wave properties can be identified before and/or after earthquakes, determine the underlying physical mechanisms, and assess the potential for operational forecasting of ruptures on meter-scale...

The U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) awarded a $1,250,000 Cooperative Agreement under the Pipeline Safety Research Competitive Academic Agreement Program (CFDA 20.724) to the Trustees of the Stevens Institute of Technology. The award funds research to develop innovative solutions for enhancing pipeline safety and integrity, with a focus on preventing and mitigating risks of stress corrosion cracking. The project will involve...

This National Science Foundation (CFDA 47.041 - Engineering) Project Grant award provides $1,000,000 to Oregon State University (OSU) to conduct research on the dynamic in-situ responses and liquefaction of gravelly soil deposits. The research aims to: Dynamically load a well-characterized gravel deposit to directly observe the seismic and post-seismic responses under 1G stress states; Determine the fundamental in-situ thresholds for initiating nonlinearity, shear degradation/inelasticity, and...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to quantify the role of pressure gradients in nearshore sediment mobility and transport using distributed fiber-optic sensing. The $298,491 award to Oregon State University will fund laboratory experiments and field observations to improve understanding of how wave-driven pressure gradients near the seafloor influence sand movement and coastal evolution. The project will...

This $555,746 five-year project grant awarded by the National Science Foundation's Engineering program (CFDA 47.041) supports research at Portland State University to advance geotechnical site investigation methods. The research aims to (1) develop a critical state line-based approach to interpret cone penetration test data for standard and non-standard soil types, enabling more accurate determination of soil properties, and (2) quantify uncertainties associated with site investigation data to...
