An integrated water model quantifies the impact of water management on thermoelectric power plant generation.

Scientists are exploring ways to derive more accurate predictions that can help with preparations for changing sea levels

Researchers quantified the land surface water and energy budget responses to AR and non-AR induced precipitation by evaluating a 35-year regional climate simulation at 6 km grid spacing of the hydroclimate in the western United States.

Uncertainty in assumed effective emission height from anthropogenic sources strongly affects the concentration and vertical profile of sulfur dioxide (SO2) and aerosols

Researchers from Pacific Northwest National Laboratory reviewed the current state of knowledge about the impacts of climate change on soil microorganisms in different climate-sensitive soil ecosystems.

A new study examines how back how back-to-back extreme events can affect a forest landscape.

Enzyme production in peatlands reduces carbon lost to respiration under future high temperatures.

The microbial communities within the loose, friable aggregations of organic and mineral components in soil are highly organized spatially, shaped in part by the structure of the soil itself.

Nitrogen is a critical nutrient regulating productivity in many ecosystems and influences nutrient availability by affecting organic matter decomposition rates.

Biogeochemical activity in the hyporheic zone (HZ), sediments where the flowing waters of a river mix with shallow groundwater, supports many of the biological processes that occur within a watershed.

Turbulent vertical fluxes of heat, water vapor, and carbon dioxide (CO2) occur constantly between land surfaces and the atmosphere.

Co-authors of a paper in Hydrological Processes led by PNNL researchers Zhangshuan Hou, Timothy Scheibe, and Christopher Murray, produced a map that identifies different classes of sediments which compose the riverbed along the Hanford ...

A multi-institutional team of scientists developed a new sensitivity analysis framework using Bayesian Networks to quantify which parameters and processes in complex multi-physics models are least understood.

Reactive transport models (RTMs) are used to describe and predict the distribution of chemicals in time and space, in both marine and terrestrial (surface and near-surface) environments where microbially-mediated processes govern...

Hydrologic exchange flows (HEFs) increase the contact between river water and subsurface sediments thereby playing a critical role in biogeochemical and ecological functions along river corridors.
