A new technique using dissolved noble gas tracers sheds light on how water moves through an aquifer, with implications for water resources and their vulnerability to climate change.
Permafrost thawing associated with climate warming increases contributions to streamflow by deeper, cooler groundwater flow paths, which may result in lower summer stream temperatures.
A numerical model of groundwater-surface water systems shows how floodplain evaporation can reverse stream-groundwater flow and produce strong buoyancy changes associated with salinity.
A new study shows that mesquites employ hydraulic redistribution to move water between soil layers in the savannas of Santa Rita.
Lab-built streams reveal new insights into turbulence-driven exchange of dissolved substances between stream water and sediments below.
A new modeling blueprint seeks to unify sedimentology, hydrology, and hydrogeology in the modeling of streambeds.
Increased glacial melt is boosting winter streamflows by filling aquifers, a new study on an Alaskan river suggests.
Overpumping and other activities that affect groundwater levels could combine with increased nitrogen runoff to amplify threats to human and environmental health.
New models of saltwater-freshwater mixing in coastal aquifers show how salinity varies throughout the year, with implications for what happens to groundwater pollutants before they reach the ocean.
