GROUNDWATER WITHDRAWAL ESTIMATION USING INTEGRATED REMOTE SENSING PRODUCTS AND MACHINE LEARNING [PDF]

open access: yes, 2022
The rising demands for water, food, and energy primarily driven by the increasing global population constitute a pressing issue worldwide. Therefore, the water-food-energy nexus plays a substantial role in developing globally applicable sustainable ...

Climate and Anthropogenic Perturbations Impact Stream Geochemistry

open access: yesEarth's Future, Volume 14, Issue 1, January 2026.
Abstract Climate and anthropogenic perturbations, including warming temperatures, shifting precipitation patterns, and changes in contamination, can alter geochemical reactions that shape stream chemistry. To date, our understanding of how climate and humans are altering water‐rock interactions and geogenic stream chemistry is limited, partly because ...

ECOSTRESS Evapotranspiration Estimates Across Temporal and Spatial Scales in Arid and Semi‐Arid Southern Arizona, USA

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Evapotranspiration (ET) is the largest outgoing water flux in the hydrologic cycle but the most difficult component to quantify. In arid and semi‐arid regions, ET can be up to 99% of precipitation and thus critical for land and water managers to quantify accurately.

A Comprehensive Overview of Single-Source and Dual-Source Energy Balance Algorithms ‎for Estimating Actual Evapotranspiration [PDF]

open access: yesآب و توسعه پایدار
Evapotranspiration estimation is one of the most important water balance components and involves various complexities. In general, energy balance models are divided into two categories: single-source and two-source models. Choosing a model to estimate ET

Leading Satellite‐Based Evapotranspiration Products Insufficiently Capture Interannual Variability: Evidence From GRACE/FO and In Situ Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Satellite‐based evapotranspiration (ET) products such as OpenET and GLEAM are widely used for drought monitoring and ecosystem‐climate studies. However, their ability to accurately capture interannual variability (IAV), a key requirement for such applications, remains under‐evaluated.

Assessment of the Effectiveness of GRACE Observations in Monitoring Groundwater Storage in Poland

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract The Gravity Recovery and Climate Experiment (GRACE/GRACE‐FO) mission have been providing global data on terrestrial water storage (TWS) for over 20 years. This study aimed to assess the effectiveness of GRACE/GRACE‐FO observations for monitoring groundwater storage (GWS) in Poland.
