Postfire hydrologic response along the central California (USA) coast: Insights for the emergency assessment of postfire debris-flow hazards
Matthew A. Thomas, Jason W. Kean, Scott W. McCoy, Donald N. Lindsay, Jaime Kostelnik, David B. Cavagnaro, Francis K. Rengers, Amy E. East, Jonathan Schwartz, Douglas P. Smith, Brian D. Collins
2023, Landslides (20) 2421-2436
The steep, tectonically active terrain along the Central California (USA) coast is well known to produce deadly and destructive debris flows. However, the extent to which fire affects debris-flow susceptibility in this region is an open question. We documented the occurrence of postfire debris floods and flows following the landfall...

These systems face several challenges, including worsening drought, altered wildfire regimes, climate change, and the spread of invasive species. These factors...
Ensemble estimation of historical evapotranspiration for the conterminous U.S.
Meredith Reitz, Ward E. Sanford, Samuel Saxe
2023, Water Resources Research (59)
Evapotranspiration (ET) is the largest component of the water budget, accounting for the majority of the water available from precipitation. ET is challenging to quantify because of the uncertainties associated with the many ET equations currently in use, and because observations of ET are uncertain and sparse....
Hydrogeomorphic changes along mid-Atlantic coastal plain rivers transitioning from non-tidal to tidal: Implications for a rising sea level
Daniel Kroes, Gregory E. Noe, Cliff R. Hupp, Thomas Rossiter Doody, P.A. Bukaveckas
2023, Estuaries and Coasts (46) 1438-1458
Sea level rise is affecting reaches of coastal rivers by increasing water levels and propagating tides inland. The transition of river systems into tidal estuaries has been neglected in hydrogeomorphic studies. A better understanding of transitioning reaches is critical to understanding ecosystem dynamics, services, and developing predictive capabilities of change...
Identifying hydrologic signatures associated with streamflow depletion caused by groundwater pumping
Dana A. Lapides, Samuel Zipper, John C. Hammond
2023, Hydrological Processes (37)
Groundwater pumping can reduce streamflow in nearby waterways (‘streamflow depletion’), a process which must be accounted for in integrated management of surface and groundwater resources. However, causal identification of streamflow depletion from hydrographs alone is challenging because pumping impacts are masked by other drivers of hydrologic variability. To identify potential...

2023, Remote Sensing of Environment (294)
Arctic-boreal wetlands, important ecosystems for biodiversity and ecological services, are experiencing hydrological changes including permafrost thaw, earlier snowmelt, and increased wildfire susceptibility. These changes are affecting wetland productivity, species diversity, and biogeochemical cycles. However, given the diverse forms and structures of wetland vegetation...
Groundwater residence times in glacial aquifers—A new general simulation-model approach compared to conventional inset models
J. Jeffrey Starn, Leon J. Kauffman, Daniel T. Feinstein
2023, Scientific Investigations Report 2021-5142
Groundwater is important as a drinking-water source and for maintaining base flow in rivers, streams, and lakes. Groundwater quality can be predicted, in part, by its residence time in the subsurface, but the residence-time distribution cannot be measured directly and must be inferred from models. This report compares residence-time distributions...

Pliocene–Pleistocene hydrology and pluvial lake during Marine Isotope Stages 5a and 4, Deep Springs Valley, western Great Basin, Inyo County, California
Jeffrey R. Knott, Shannon A. Mahan, Jordan E. Bright, Lindsey Langer, Adam Ramirez, Kyle McCarty, Anna L. Garcia
2023, Quaternary Research (115) 160-178
Deep Springs Valley (DSV) is a hydrologically isolated valley between the White and Inyo mountains that is commonly excluded from regional paleohydrology and paleoclimatology. Previous studies showed that uplift of Deep Springs ridge (informal name) by the Deep Springs fault defeated streams crossing DSV and hydrologically isolated...

Carleton R. Bern, Cory A. Williams, Christopher G. Smith
2023, Scientific Investigations Report 2023-5056
Selenium in aquatic ecosystems of the lower Gunnison River Basin in Colorado is affecting the recovery of populations of endangered, native fish species. Dietary exposure is the primary pathway for bioaccumulation of selenium in fish, and particulate selenium can be consumed directly by fish or by the invertebrates on which...

Adam Wymore, Adam Ward, Ellen Wohl, Judson Harvey
2023, Frontiers in Water (3)
River corridors integrate the active channels, geomorphic floodplain and riparian areas, and hyporheic zone while receiving inputs from the uplands and groundwater and exchanging mass and energy with the atmosphere. Here, we trace the development of the contemporary understanding of river corridors from the perspectives of geomorphology, hydrology, ecology,...
