Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge
A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

Review of the 2020 Statewide Suitability Survey of ASR and AR for Texas Aquifers
Since publication in 2020, the Statewide Survey of Aquifer Suitability for Aquifer Storage and Recovery Projects or Aquifer Recharge Projects interactive map experience and method have inspired researchers, water providers, and policymakers to explore the potential of aquifer storage and recovery and aquifer recharge in Texas.

Managed Aquifer Recharge Operations and Design under Hydrologic Uncertainty
Integrated hydrologic modeling uses dual ensembles of MAR operations and IES‐derived parameters to evaluate mounding, inundation, and transport risks under climate extremes. Exceedance‐probability metrics quantify environmental risks across the MAR impact zone, showing drain‐controlled mound limits, recovery effects, and pathways to interdunal and ...

A New Approach to Transforming Airborne Electromagnetic Data into Models of Sediment Type
A new methodology provides the relationship needed to transform electrical resistivity measurements from airborne electromagnetic surveys to sediment type. By accounting for the physics of the measurement and the quality of the driller's logs used in developing the transform, the method improves the accuracy of derived sediment type models.

Evaluating Suitability for Surface Managed Aquifer Recharge to Enhance Dry‐Season Stream Flows
Identifying suitable sites for surface MAR projects to enhance dry‐season stream flow requires evaluating the geology of the aquifer, depth to groundwater, soil permeability, topographic slope, the distance between the infiltration basin and receiving surface water, and other factors.

Management of Seawater Intrusion in Coastal Aquifers of Caspian Sea
As result of density difference between seawater and fresh water in coastal aquifers, a transition zone between two fluids is formed. A wedge of saltwater can be entered in coastal areas to the aquifer.

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Abstract At many sites, chlorinated ethenes in some of the monitoring wells remain above cleanup goals, even though the water produced by the pumped wells of the pump‐and‐treat system meets the goals. Regulators and site risk managers need tools to determine whether it is appropriate to shut‐down the pump‐and‐treat system and transition to monitored ...
