Jeffrey Keck, Erkan Istanbulluoglu, Jessica Lundquist, Christina Bandaragoda, Kristin Jaeger, Guillaume S. Mauger, Alex Horner-Devine
2022, Water Resources Research (58)
Modeled stream discharge is often used to drive sediment transport models across channel networks. Because sediment transport varies non-linearly with flow rates, discharge modeled from daily total precipitation distributed evenly over 24-hrs may significantly underestimate actual bedload transport capacity. In this study, we assume bedload transport capacity determined from a...

Michaela Wenner, Kate E. Allstadt, Weston Thelen, Andrew Lockhart, Jacob Hirschberg, Brian W. McArdell, Fabian Walter
2022, Bulletin of the Seismological Society of America (112) 2376-2395
A change in surface loading causes the Earth’s surface to deform. Mass movements, such as debris flows, can cause a tilt large enough to be recorded by nearby instruments, but the signal is strongly dependent on the mass loading and subsurface parameters. Specifically designed sensors for such measurements (tiltmeters) are...
