Terrestrial Poor Ecohealth Areas Continue to Expand Across Asian Drylands

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The 7th Rio declaration principle emphasizes global collaboration to protect and restore ecosystem health. While dryland ecosystem health (EH) remains critical to global sustainability agendas, its long‐term regional dynamics remain poorly constrained across the Asian drylands (AD), where land management decisions increasingly shape ecological

Nitrogen Memoryscapes: Typologies of Nitrogen Inputs and Riverine Loads Across the Continental United States

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Nitrogen pollution has severely impacted inland and coastal waters, contributing to eutrophication, harmful algal blooms, and drinking water contamination. Reducing nitrogen inputs is widely expected to improve water quality, but watershed responses to changing nitrogen surplus are often nonlinear and delayed, complicating expectations of ...

Exploring the Influence of Morphologic Heterogeneity and Discharge on Downstream Transport in Streams With Multiple Logjams: 2. Insight From Numerical Models

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Logjams in streams create complex morphologic features such as pools, bars, and branching channels that enhance stream water storage and force water through the streambed. We examine how these features alter solute retention in stream corridors as discharge increases, backwaters expand, new channels activate, and jams become more submerged ...

Vertical Hydraulic Gradients as Key Calibration Constraints in Regional Groundwater Models

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract In typical clastic sedimentary aquifer systems, interbedded coarse‐ and fine‐grained deposits impede vertical flow and promote horizontal flow. This effect, known as vertical anisotropy, is often underestimated in regional groundwater models, leading to overestimated vertical aquifer communication.

A Hierarchical Deep Learning Framework for Runoff Prediction Using Raster‐Based Spatial Representations

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Large‐sample deep learning runoff models rely primarily on aggregated catchment attributes, which may obscure informative spatial patterns. Using 531 watersheds in the contiguous United States, we develop a hierarchical deep learning framework that represents static watershed properties from watershed‐averaged raster aggregation to ...
