Dams and Their Legacies Shape Biogeochemical Evolution of Riparian Sediments

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Dams and their legacies have substantially altered riparian ecosystems worldwide and these effects could persist for decades or centuries into the future. However, how biogeochemical characteristics of riparian sediments evolve with depth and time post dam removal is poorly understood.

Research Priorities for Robust Climate Assessments in the United States

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Scientific assessments play a critical role in synthesizing evidence to support evidence‐based decision‐making in many sectors and topics. For climate change, large‐scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from ...

Quantifying Deep Groundwater Contributions to Streamflow With Inequality‐Constrained EEMMA From Sparse Isotope Series in Alpine Permafrost Basins

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract In alpine permafrost basins, dry‐season runoff largely depends on subpermafrost groundwater (BPG, deep groundwater), yet cryohydrogeological conditions are complicated by time‐varying hydrothermal regimes. Combined with the storage and regulation effects of permafrost on runoff, hydrograph‐based estimates of the fractional contribution of BPG ...

Hydrologic Retention and Sediment Redistribution Following Beaver Dam Analog (BDA) Installation in a Flashy, Ephemeral, Stormwater‐Impacted Stream

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract In many watersheds, urbanization and agriculture have altered stream hydrology and morphology, increasing flow variability, and sediment transport imbalances. Beaver dam analogs (BDAs) offer a process‐based alternative to conventional gray or hard‐engineered stormwater infrastructure to slow flow, promote sediment deposition, and enhance ...

A Probabilistic Pathway Framework for River–Sea Connectivity in Distributary Networks: A Case Study in the Guangdong–Hong Kong–Macao Greater Bay Area

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Hydrological connectivity regulates river–sea exchange by controlling freshwater delivery, salinity intrusion, sediment transport, and biogeochemical fluxes that sustain deltaic ecosystems. In distributary river systems, connectivity is mediated by multiple alternative downstream pathways, yet most assessments rely on network‐averaged indices ...
