Fine‐Scale Spatial Variation of Evapotranspiration Across Tropical Land‐Cover Mosaics Revealed by UAV Thermography

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
We study evapotranspiration (ET), a key flux in the hydrological cycle, across heterogeneous tropical land‐cover mosaics in lowland Sumatra featuring secondary forest patches, oil palm plantations, and shrubland. We apply high‐resolution UAV thermography and an energy‐balance model to derive ET across three mosaic landscapes (Areas 1–3).

Three‐Dimensional Analysis of Heat Tracer Transport With High‐Resolution Subsurface Heterogeneity Characterization in a Complex Aquifer System

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Accurate predictions of tracer transport in complex aquifer systems remain a formidable challenge, primarily owing to the spatial heterogeneity of hydraulic conductivity (K). Here, we conducted a forced‐gradient heat tracer test within a highly heterogeneous glaciofluvial deposit, injecting chilled water and monitoring temperature at depth ...

Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...
