Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,
