Tool and Database for Estimating Potential Longevity of Colloidal Activated Carbon Barriers for PFAS in Groundwater

open access: yesRemediation Journal, Volume 35, Issue 3, Summer 2025.
ABSTRACT This study presents a planning‐level graphical tool and a regression equation model for estimating the longevity of Colloidal Activated Carbon (CAC) barriers for treating per‐ and polyfluoroalkyl substances (PFAS) in groundwater. The tool development incorporated information from field‐scale CAC barriers, including design data from 17 sites ...

Evaluation of Different Scenarios of Water Resources Management in the Gorganroud basin using WEAP and MODFLOW Models

open access: yesعلوم آب و خاک, 2020
Increase in population, agricultural development, and the reduction of surface water resources have resulted in an untapped harvest of ground water. On the other hand, the lack of attention to the balance between the exploitation and recharge of aquifers

Evaluation of Multiple Groundwater Management Targets by Applying Frequency, Duration, and Magnitude Metrics to Water Table Depth Targets

open access: yesWater Resources Research, Volume 61, Issue 4, April 2025.
Abstract Groundwater resource management faces significant challenges due to groundwater overdraft and waterlogging. Establishing thresholds of the water table depth (WTD) is crucial to ascertain whether WTDs align with ranges conducive to the health of social‐ecological systems.

A New Comprehensive Model to Simulate and Optimize Fluid Flow in Complex Well‐Formation System for In Situ Leaching Uranium

open access: yesEnergy Science &Engineering, Volume 13, Issue 3, Page 1089-1102, March 2025.
ABSTRACT In situ leaching (ISL) is an important method for green and efficient development of sandstone‐type uranium ore. It achieves ISL of uranium through the deployment of injection and extraction vertical well patterns. The optimization of parameter matching between injection and extraction wells is key to improving the efficiency of uranium ...

The Unexploited Treasures of Hydrological Observations Beyond Streamflow for Catchment Modeling

open access: yesWIREs Water, Volume 12, Issue 2, March/April 2025.
Caption: In situ and satellite‐based observations of hydrological variables beyond streamflow are valuable to improve modeling catchment hydrology (modified from Fisher 2005; CC BY‐SA 4.0). ABSTRACT While measured streamflow is commonly used for hydrological model evaluation and calibration, an increasing amount of data on additional hydrological ...
