Journal ArticleDOI
Hydrologic impacts of thawing permafrost—A review
TL;DR: In this article, the authors highlight promising advances in characterization and modeling of permafrost regions and present ongoing research challenges toward projecting hydrologic and ecologic consequences of permaferost thaw at time and spatial scales that are useful to managers and researchers.
Journal ArticleDOI
Increased groundwater to stream discharge from permafrost thawing in the Yukon River basin: Potential impacts on lateral export of carbon and nitrogen
TL;DR: In this paper, a general upward trend in groundwater contribution to streamflow of 0.7-0.9%/yr and no pervasive change in annual flow was observed. And the increases in groundwater contributions were caused predominately by climate warming and permafrost thawing that enhances infiltration and supports deeper flowpaths.
Journal ArticleDOI
A Reservoir of Nitrate Beneath Desert Soils
Michelle Ann Walvoord,Fred M. Phillips,David A. Stonestrom,R. Dave Evans,P. C. Hartsough,P. C. Hartsough,Brent D. Newman,Robert G. Striegl +7 more
TL;DR: Consideration of the subsoil reservoir raises estimates of vadose-zone nitrogen inventories by 14 to 71% for warm deserts and arid shrublands worldwide and by 3 to 16% globally.
Journal ArticleDOI
Implications of projected climate change for groundwater recharge in the western United States
Thomas Meixner,Andrew H. Manning,David A. Stonestrom,Diana M. Allen,Hoori Ajami,Kyle W. Blasch,Andrea E. Brookfield,Christopher L. Castro,Jordan F. Clark,David Gochis,Alan L. Flint,K. Neff,Rewati Niraula,Matthew Rodell,Bridget R. Scanlon,Kamini Singha,Michelle Ann Walvoord +16 more
TL;DR: In this article, an analysis of the potential impact of climate change on groundwater recharge across the western United States (west of 100° longitude) is presented synthesizing existing studies and applying current knowledge of recharge processes and amounts.
Journal ArticleDOI
Influence of permafrost distribution on groundwater flow in the context of climate‐driven permafrost thaw: Example from Yukon Flats Basin, Alaska, United States
TL;DR: In this paper, the authors investigate the role of permafrost in controlling groundwater flow paths and fluxes in interior Alaska and evaluate potential hydrologic consequences of permfrost degradation in the Yukon Flats Basin (YFB).
