A Model‐Agnostic Representation of Prairie Pothole Hydrology: Enhancing Generality and Implementation Across Hydrological Models

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Modeling streamflow in low‐lying, flat, and pothole‐dominated prairie or Arctic regions is challenging due to variable non‐contributing areas that influence how runoff translates to streamflow. Several modeling approaches have been developed to represent these dynamics, but many (a) lump depressions and permit spill only after a fixed capacity

Water Markets, Regulation and Technology: A Survey of Irrigators in Washington State

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Water markets hold potential for helping communities in the western United States adapt to water scarcity, but market activity remains low. Reforms to policies and institutions could spur more market activity but could also be politically infeasible if water users opposed them.

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Reservoirs are vital tools for managing riverine water resources but also influence water quality through in‐lake nutrient (i.e., nitrogen [N] and phosphorus [P]) dynamics that affect downstream ecosystems. This study presents a multiscale spatiotemporal characterization of water quality in Carlyle Lake, an agriculturally impacted reservoir in

Extending the MMMT Temporal Change Detection Tool to Assess Significant Shifts in Diverse Environmental Datasets

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT This paper examines applications of the visual modified Mood's median test (MMMT) tool, which was originally developed for assessing temporal changes in streamflow regimes, to assess changes in a broader range of critically important environmental variables.

Climate Change Impacts on Hydrology in the Upper James Watershed, Virginia

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Hydrological modeling of the Upper James Watershed (UJW), Virginia, is critical for predicting water availability, flood management, agriculture, ecosystem protection, and hydropower production under increasing climate change. The Hydrologic Engineering Center–Hydrologic Modeling System (HEC‐HMS) is applied to evaluate climate change impacts ...

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Stationary and Nonstationary Influences of Teleconnections on Terrestrial Water Storage Anomalies in Vietnam

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Previous studies of teleconnection (TC) impacts on Terrestrial Water Storage Anomalies (TWSA) rarely focus on Vietnam or on the nonstationary nature of TC–TWSA relationships. This study addresses these gaps by examining both stationary and nonstationary TC influences on TWSA using correlation analysis (Pearson and cross‐spectral methods) and ...

Development of a SWAT+ Model to Improve Conservation Practice Efficacy for Protecting Stream Health in Karst Pasturelands

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Placing appropriate conservation practices in critical source areas of pollutants can benefit stream health in karst environments susceptible to agricultural pollution. Watershed models, such as the Soil and Water Assessment Tool+ (SWAT+), can optimize both practice selection and placement across the landscape, but to our knowledge no studies ...

Groundwater Contributions to Daily Nitrogen and Phosphorus Loads and Implications for Prediction in Watersheds in South Korea

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Understanding watershed water quality dynamics is essential for sustainable management, yet accurate nutrient load prediction remains challenging under strong inter‐annual variability. To address this limitation, this study presents a hybrid modelling framework that integrates baseflow information into a machine‐learning structure to improve ...

Integrating Modeled Flood Maps From the National Water Model and Diverse Sources for Enhanced Forecasting and Preparedness

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Flood mapping is critical for flood forecasting, preparedness, and risk management. In the United States, multiple federal agencies and organizations generate or archive flood inundation maps (FIM) using diverse models, data sources, and standards.
