1. A New Approach to Transforming Airborne Electromagnetic Data into Models of Sediment Type.
PMID:日期:2026-09-22The availability of 20,000 line-kilometers of airborne electromagnetic (AEM) data and the digitization of driller's logs across the Central Valley of California enables the transformation of AEM measurements of electrical resistivity into sediment type descriptions. A critical challenge is establishing the rock physics transform that relates resistivity to sediment type. Two approaches have been applied in the Central Valley; they differ in the model used to link resistivity to sediment type and in the level of confidence placed in the information in the driller's logs, with the latter determining the level of spatial heterogeneity allowed in the transform parameters. We developed a new methodology that builds on the strengths of each approach. Applied in the Kaweah Subbasin in California, we used resistivity profiles derived from AEM data, sediment type descriptions from driller's logs, and water level data from wells. The methodology incorporates the physics of the AEM measurement and solves for transform parameters with a scale of spatial variability determined through an adjustable hyperparameter that accounts for the presumed quality of the driller's logs. The derived transform was applied to all resistivity data from the AEM survey in the subbasin to generate a model of sediment type. When we compare our model with those generated using established methods, we conclude that incorporating the physics of the measurement provides more accurate estimates of the percentage of coarse-grained materials, and that spatial variability in the transform should be accommodated in a way that reflects the quality of the driller's logs.

2. Sixty Years of the O.E. Meinzer Award: The People, Papers, and Institutions that Shaped Hydrogeology (1965-2026).
PMID:日期:2026-09-18The O.E. Meinzer Award of the Geological Society of America's Hydrogeology Division has been presented 61 times between 1965 and 2026, honoring 68 individuals. Because each award recognizes a specific publication or body of work, the winner list constitutes a 60-year record of what the hydrogeological community has considered its frontier. This note assembles a structured dataset of all recipients and the 177 representative papers listed for them on the Division's website, and analyzes the age structure of the winners, the co-authorship and thematic content of the cited works, the journals in which they appeared, and the geographic and institutional distribution of the winners. Winners have grown older by roughly 15 years since the award's 5-year publication window was removed in the 1980s, and the lag between honored work and award has risen from ~3 to 11-17 years. Mean authorship of cited papers rose from 1 to ~4, while single-author papers fell from 100% to under 11%. The keyword record moves from well hydraulics through stochastic theory, numerical modeling, and isotope geochemistry to today's climate, coastal, and permafrost themes; Water Resources Research carries 30% of all cited papers, but its share has fallen from 64 to 16% as winning science diversified. The note closes with reflections for prospective future recipients.

3. Review of the 2020 Statewide Suitability Survey of ASR and AR for Texas Aquifers.
3. 2020年德克萨斯州含水层ASR和AR全州适宜性调查综述PMID:日期:2026-09-09In 2019, the Texas Legislature directed the Texas Water Development Board (TWDB) to conduct a statewide managed aquifer recharge (MAR) suitability survey for Texas. The resulting Statewide Survey of Aquifer Suitability for Aquifer Storage and Recovery Projects or Aquifer Recharge Projects has provided an initial, regional (not site-specific) scale analysis of the potential for MAR within the 31 major and minor aquifers of Texas. The results of the survey are presented on a 50,000-ft statewide grid (89.5 sq. mi. cells), which provided coincident boundaries for intersecting GIS layers. The survey consists of three independent screenings: hydrogeological parameters, excess water, and water supply needs. Each of these three screenings considered multiple parameters scored on a weighted scale, with critical parameters receiving higher weights. The three highest screenings in a 25-grid cell search area (approximately 2240 mile) were combined to create two final suitability scorings and ratings: one for aquifer storage and recovery and one for aquifer recharge. Entities have used the survey as part of initial evaluations for MAR. Since publication in December 2020, stakeholders and interested parties have provided feedback on the methodology, impact, and potential future of the survey. This narrative review paper is a discussion of that feedback.

4. Enhancing Recharge Beneath Low-Permeability Landscapes with Small-Diameter Drywells: Token Creek, WI.
PMID:日期:2026-09-04The implementation of managed aquifer recharge (MAR) systems in the Midwest has been limited, likely due to a relative abundance of water, land use requirements, and cost. Despite limited use in the Midwest, MAR systems that source from stormwater can provide benefits in reducing flooding, while also improving shallow groundwater quality if high-quality water is infiltrated into the subsurface. We hypothesize that recharge may be safely and economically enhanced by installing shallow, small-diameter drywells that allow deeper infiltration. These installations can benefit areas where groundwater recharge is naturally low, including regions with high evapotranspirative demand and areas with lower-permeability surficial soils. In this study we assess the benefit of drywells through direct field monitoring of recharge quantity and quality via a drywell and by comparison with estimated rates of natural recharge using a one-dimensional model. Over 1 year, we found the 3.2 cm-diameter drywell to passively infiltrate an additional 30.2 to 52.2 L (best estimate 35.3) of water from rainfall, runoff, and snow melt. Compared to a model-estimated natural recharge of 177 L per year, per 1 m of landcover, implementation of a drywell can increase infiltration by 17 to 29%. Results suggest no need for pretreatment, as a large majority of the drywell water quality samples had concentrations below associated EPA limits. Additionally, this study discusses the longevity and the required installation and maintenance costs of implementing small-diameter drywells. This study builds on other studies that have assessed small-diameter drywells by assessing performance under natural runoff conditions and water quality impacts.

5. Computing Flow-Field Distortion Coefficients from Well-Construction and Formation Properties.
PMID:日期:2026-07-03Direct measurements of groundwater velocity made with borehole flowmeters in screened wells must be compensated for the effects of flow-field distortion (also known as borehole acceleration). A theoretical equation developed by Drost et al. (1968) and simple inputs describing hydraulic properties of well construction and geologic formation were programmed into an Excel workbook to facilitate computation by groundwater-flowmeter users. Tables describing the physical and hydraulic properties for well constructions and gravel pack media are provided with an example to facilitate use of the workbook. Groundwater flowlines converge or diverge as they pass from a geologic formation, through a gravel pack and well screen. The extent of flowline convergence or divergence and the value of the flow-field distortion coefficient is related to the relative changes in hydraulic conductivity of the well screen, gravel pack, and geologic formation. Convergence or divergence is accompanied by acceleration or deceleration of groundwater. Direct measurements of groundwater velocity at the center of the monitoring well can be adjusted to provide a more accurate estimate of velocity in the formation by applying a correction for flow-field distortion. Variables required to compute the flow-field distortion coefficient include the hydraulic conductivity of the gravel pack, well screen, and the geologic formation surrounding the well screen; the borehole radius, and the inside radius and outside radius of the well screen.

6. Leaky Sewers Hydraulically Disconnect from Groundwater: A Proof-of-Concept.
PMID:日期:2026-06-02Leakage from aging sewer and stormwater pipes into the subsurface poses significant environmental risks and threatens the integrity of urban infrastructure, primarily through the degradation of groundwater quality and the alteration of urban water balances. While the presence of defects within pipe networks is well-documented, accurately quantifying volumetric exchange fluxes remains a challenge due to the complex, nonlinear interactions between the pipe, the surrounding variably saturated soil, and the fluctuating groundwater level. Current modeling approaches often overlook the threshold behaviors of these systems, leading to potential inaccuracies in leakage estimation. In this study, we show for the first time that leaky pipes can become hydraulically disconnected from the underlying groundwater, a phenomenon analogous to well-known river-groundwater interactions that include disconnection. In a sewer-groundwater context, hydraulic disconnection is restricted to point sources and is strongly influenced by colmation/clogging. Through numerical modeling of a hypothetical case study, we show that the leakage flux from the pipe (in absolute terms) initially increases with declining groundwater levels, until a critical depth below the leaky pipe is reached. After this point, the hydraulic communication from the groundwater to the leaky pipe stops and the leakage flux can be considered constant. In a sensitivity analysis, we demonstrate the impact of the individual hydraulic parameters of the leaky-pipe-groundwater system on the hydraulic disconnection. We further modify the properties of the aquifer material, resulting in a hydraulic disconnection depth of 0.89 m, 1.77 m and 4.00 m below pipe for sand, loamy sand and sandy loam aquifers, respectively. This insight has important implications for leakage modeling: once hydraulic disconnection occurs, the leakage flux becomes independent of groundwater dynamics. The present study provides a proof-of-concept for the mechanism by which leaky sewers hydraulically disconnect from groundwater.

7. Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers.
PMID:日期:2026-05-14Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability, variable water flow velocities, and shorter water residence times. Consequently, there is a gap in studies assessing managed aquifer recharge effectiveness in karst aquifers. The Edwards Aquifer in south-central Texas, which provides water to over 2 million people, is an example where recharge enhancement strategies have been explored. This study synthesizes enhanced recharge measures in the Edwards Aquifer from the 1960s to 2024, assessing their benefits, limitations, and regulatory frameworks guiding these strategies. By reviewing state water codes, rules, articles, technical reports, and case studies, this study reveals purpose and methods of recharge enhancement in the region. Findings suggest that while recharge dams, designed for flood control, have contributed to enhancing recharge, their impact remains marginal compared to natural recharge volumes. Aquifer storage and recovery emerged as a key strategy to store Edwards water in other stable aquifers and the brackish zone of the Edwards Aquifer. Recirculation and springflow augmentation were explored but not implemented due to uncertainties. Other initiatives focused on enhancing the quality of water entering the aquifer. Enhanced recharge in karst aquifers (or using karst aquifers' water to enhance recharge in other aquifers) is important as societies continue to face challenges due to population growth and environmental changes.

8. Layered Radial Aquifer Model for Open-Pit Mine Closure with Managed Aquifer Recharge.
PMID:日期:2026-04-08Open-pit mine dewatering can delay post-closure pit-lake recovery and is increasingly managed using managed aquifer recharge (MAR). We develop a radially symmetric two-aquifer model that couples an unconfined aquifer, a leaky aquitard, and an underlying confined aquifer to a pit water-balance equation, extending Cook et al. (2022) to layered systems. MAR is represented by reinjecting prescribed fractions of the time-varying pumping rate at a ring radius r, with flexible allocation between unconfined and confined injection. Nondimensionalization yields transferable type curves and a design workflow controlled by K/S, Kc/Sc, Λ/S, r/r, and the far-field head ratio α. We evaluate 15 hydrogeologic scenarios (H0-H14) under three MAR allocations (no MAR, MAR, MAR). Across scenarios, reinjecting 80% of pumped water to the unconfined aquifer (MAR) reduces the time for the pit water level to return within 5 m of the pre-mining unconfined head from 21-48 year (no MAR) to 1.8-28 year, with a median recovery-time ratio of 0.17, while increasing mean pumping by a median factor of 1.31. Splitting the same reinjection fraction between unconfined and confined aquifers can further shorten recovery when vertical coupling is moderate to high (Λ/S ≳1), but increases mounding and recycling. Layering matters: for the same MAR policy, the layered base case predicts recovery times a factor of ~2-3 shorter than the homogeneous limit. The results provide screening guidance on when confined-aquifer injection can accelerate recovery without unacceptable unconfined mounding.
