The production and uptake of toxic methylmercury (MeHg) impacts aquatic ecosystems globally. Rivers can be dynamic and difficult systems to study for MeHg production and bioaccumulation, hence identifying sources of MeHg to these systems is both challenging and important for resource management within rivers and main-stem reservoirs. Riparian zones, which...

Amanda Demopoulos, Jill Bourque, Jennifer McClain Counts, Nicole Cormier, Ken Krauss
2024, Diversity (16)
Mangrove restoration efforts have increased in order to help combat their decline globally. While restoration efforts often focus on planting seedlings, underlying chronic issues, including disrupted hydrological regimes, can hinder restoration success. While improving hydrology may be more cost-effective and have higher success rates than planting seedlings alone, hydrological restoration...
Concepts and evolution of urban hydrology.
Tim D. Fletcher, Matthew J. Burns, Kathryn L Russell, Perrine Hamel, Sophie Duchesne, Frédéric Cherqui, Allison H. Roy
2024, Nature Reviews Earth & Environment (5) 789-801
Urbanization and climate change are exacerbating the flood risk and ecosystem degradation in urban catchments, with traditional stormwater management systems often overwhelmed. In this Review, we discuss changes in urban hydrology and approaches to stormwater management. Roughly 90% of rainfall on impervious surfaces and drainage infrastructure becomes run-off, enhancing rainfall...
Evaluating hydrologic model performance for characterizing streamflow drought in the conterminous United States
Caelan Simeone, Sydney Foks, Erin Towler, Timothy O. Hodson, Thomas M. Over
2024, Water (16)
Hydrologic models are the primary tools that are used to simulate streamflow drought and assess impacts. However, there is little consensus about how to evaluate the performance of these models, especially as hydrologic modeling moves toward larger spatial domains. This paper presents a comprehensive multi-objective approach to systematically evaluating the...

Adam R. Trevisan, Cory A. Russell, Hayden A. Lockmiller, Derrick L. Wagner, Jessica S. Correll, Katherine J. Knierim
2024, Scientific Investigations Report 2024-5093
Oklahoma Groundwater Law (Oklahoma Statute § 82-1020.5) requires that the Oklahoma Water Resources Board conduct hydrologic investigations to determine the maximum annual yield for the State’s groundwater basins. The Boone and Roubidoux aquifers (also known as the Springfield Plateau aquifer and Ozark aquifer, respectively) are bedrock aquifers that extend from...
Direct measurements of firn-density evolution from 2016 to 2022 at Wolverine Glacier, Alaska
Max Stevens, Louis C. Sass, Caitlyn Florentine, Christopher J. McNeil, Emily Baker, Katherine Eleanore Bollen
2024, Journal of Glaciology (70)
Knowledge of snow and firn-density change is needed to use elevation-change measurements to estimate glacier mass change. Additionally, firn-density evolution on glaciers is closely connected to meltwater percolation, refreezing and runoff, which are key processes for glacier mass balance and hydrology. Since 2016, the U.S. Geological Survey...

Streams, springs, and volcanic lakes for volcano monitoring
Steven E. Ingebritsen, Shaul Hurwitz
2024, Scientific Investigations Report 2024-5062-F
IntroductionVolcanic unrest can trigger appreciable change to surface waters such as streams, springs, and volcanic lakes. Magma degassing produces gases and soluble salts that are absorbed into groundwater that feeds streams and lakes. As magma ascends, the amount of heat and degassing will increase, and so will any related geochemical...
Volcanic gas monitoring
Jennifer L. Lewicki, Christoph Kern, Peter J. Kelly, Patricia A. Nadeau, Tamar Elias, Laura E. Clor
2024, Scientific Investigations Report 2024-5062-E
IntroductionAs magma rises through the crust, decreasing pressure conditions allow volatiles to exsolve from the magma. These volatiles then migrate upward through the crust, where they can be stored at shallower levels or escape to the atmosphere. Rising magma also heats rock masses beneath volcanic centers, causing water in shallow...
New insights on the origin of the Richardson-Richards equation
John R. Nimmo
2024, Hydrological Sciences Journal (69) 2153-2158
The Richardson-Richards equation (RRE), despite known shortcomings especially in regard to preferential flow, provides the basis of the vast majority of unsaturated flow models in use today. L.F. Richardson published this equation in 1922, nine years before L.A. Richards. Whereas Richards approached this problem directly from the groundbreaking developments of...

Janet R. Barclay, Madeleine J. Holland, John R. Mullaney
2024, Scientific Investigations Report 2024-5090
Elevated nitrogen loads are pervasive in the Long Island Sound, an estuary that receives freshwater and nutrients from both surface-water and groundwater discharge. Surface-water nitrogen loads to the Long Island Sound are relatively well characterized, but less is known about groundwater-transported nitrogen loads. Prior work on the northern shore of...

Galen Gorski, Laurel Larsen, Jordan Wingenroth, Liang Zhang, Dino Bellugi, Alison P. Appling
2024, Water Resources Research (60)
We developed a suite of models using deep learning to make hindcast predictions of the 7‐day average backward‐looking nitrate concentration at 46 predominantly agricultural sites across the midwestern and eastern United States. The models used daily observations of discharge and meteorological variables and watershed attributes describing anthropogenic modification to hydrology, nitrogen...

Dylan J. Irvine, Kamini Singha, Barret L. Kurylyk, Martin A. Briggs, Yakub Sebastian, Douglas Tait, Ashley Helton
2024, Journal of Hydrology (644)
Interactions between groundwater and surface water sustain groundwater-dependent ecosystems and regulate river temperature and biogeochemical cycles, amongst many other processes. These interactions occur in freshwater environments including rivers, springs, lakes, and wetlands, and in coastal environments via tidal pumping, submarine groundwater...

2024, Nature Water (2) 815-826
Transitions between dry and wet hydrologic states are the defining characteristic of non-perennial rivers and streams, which constitute the majority of the global river network. Although past work has focused on stream drying characteristics, there has been less focus on how hydrology, ecology and biogeochemistry respond and interact during stream...
Evaluating a process-guided deep learning approach for predicting dissolved oxygen in streams
Jeffrey M Sadler, Lauren Elizabeth Koenig, Galen Gorski, Alice M. Carter, Robert O. Hall Jr.
2024, Hydrological Processes (38)
Dissolved oxygen (DO) is a critical water quality constituent that governs habitat suitability for aquatic biota, biogeochemical reactions and solubility of metals in streams. Recently introduced high-frequency sensors have increased our ability to measure DO, but we still lack the capacity to understand and predict DO concentrations at high spatial...

Keira Johnson, Kathi Jo Jankowski, Joanna C. Carey, Lienne R. Sethna, Sidney A. Bush, Diane M. McKnight, William H. McDowell, Adam S. Wymore, Pirkko Kortelainen, Jeremy B. Jones, Nicholas Lyon, Hjalmar Laudon, Amanda Poste, Pamela L. Sullivan
2024, Journal of Geophysical Research Biogeosciences (129)
The seasonal behavior of fluvial dissolved silica (DSi) concentrations, termed DSi regime, mediates the timing of DSi delivery to downstream waters and thus governs river biogeochemical function and aquatic community condition. Previous work identified five distinct DSi regimes across rivers spanning the Northern Hemisphere, with many rivers exhibiting multiple DSi regimes...
