Long range experimental hydrologic forecasting for the eastern U.S. [PDF]

, 2002
We explore a strategy for long-range hydrologic forecasting that uses ensemble climate model forecasts as input to a macroscale hydrologic model to produce runoff and streamflow forecasts at spatial and temporal scales appropriate for water management ...

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Decadal climate variability and increasing exposure of Chilean agriculture

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Central Chile has undergone a steady shift from traditional annual crops to fruit orchards and vineyards, and a decline in the area dedicated to annual crops. This transition coincides with a decrease in precipitation and an increase in temperature.

Hydrological Alteration Index as an Indicator of the Calibration Complexity of Water Quantity and Quality Modeling in the Context of Global Change [PDF]

, 2019
Modeling is a useful way to understand human and climate change impacts on the water resources of agricultural watersheds. Calibration and validation methodologies are crucial in forecasting assessments.

Literature Review of Catchment Models in Aotearoa New Zealand for Ecological and Social Climate Change Effects

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Shifting climatic averages and extremes are affecting both environmental and anthropogenic communities. This is a growing concern, especially for social–ecological systems (SES) such as lakes and their catchments, which integrate ecological and societal subsystems.

Bayesian recursive parameter estimation for hydrologic models [PDF]

, 2001
The uncertainty in a given hydrologic prediction is the compound effect of the parameter, data, and structural uncertainties associated with the underlying model.

Size‐based regulation and water quality: Evidence from the Iowa hog industry

American Journal of Agricultural Economics, Volume 108, Issue 3, Page 829-855, May 2026.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

The Spatial Coherence of European Droughts – Final Report [PDF]

, 2009
Drought can cause serious problems across much of Europe. Many droughts are localised and short, but others are widespread and cause environmental and social effects that cross international boundaries.

Characterizing Improvements in Ensemble Forecast Performance Over the Last Decade: A Retrospective Analysis of the Hydrologic Ensemble Forecast Service (HEFS)

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Hydrologic forecasts are essential for mitigating water‐related risks. However, little work has explored whether operational ensemble forecasts have improved over time, particularly with respect to probabilistic performance and in cases with limited data.

The Role of Baseflow Data Assimilation in Hydrologic Modeling and Peak Flow Prediction

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent studies have revealed that subsurface water storage and flow pathways contribute a substantially larger share of streamflow than previously assumed. However, because representations of these subsurface contributions in most hydrologic models are uncertain and often biased, they can strongly influence simulated streamflow generation and ...
