Point-source submarine groundwater discharge (PSGD) delivers mass and solutes and locally reduces salinity along karstic coasts, yet the geometry of conduits conveying meteoric and mixed waters is rarely imaged. Here we present the first ma...
Predicting Groundwater Hydrochemical Facies in Three Dimensions with Random Forest Classification, USA [0.03%]
基于随机森林分类的三维地下水水文化学相预测 美国案例

Paul E Stackelberg et al.
A random forest classification (RFC) model was developed to predict hydrochemical facies (HCFs) of groundwater in three dimensions across the conterminous United States (CONUS). Major-ion data from 152,673 sites were used to categorize grou...

Groundwater supplies are stressed by climatic trends, increasing withdrawals, and multiple competing uses, especially in arid and semi-arid environments. We propose opportunistic recharge enhancement (ORE) as a cross-disciplinary, scalable ...

Open-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 ...
Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA [0.03%]
美国威利斯顿盆地达科他组深部地下水总溶解固体含量制图
Michael J Stephens,Bennett E Hoogenboom,Lyndsay B Ball et al.
Michael J Stephens et al.
Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to...
Bronze Age Sacred Wells of Sardinia, Italy: Groundwater Access Without Water Utility [0.03%]

In Late Bronze Age Sardinia, Italy (ca. 1350-1200 BC), communities constructed distinctive stone structures centered on vertical shafts intersecting the groundwater table or monumentalized natural springs. Conventionally termed pozzi sacri ...
Hydroclimatic Drivers of Groundwater Resilience in Cold Humid Regions [0.03%]
寒冷湿润地区地下水弹性的水文气候驱动因素分析

Nicole Blin et al.
Effective water resource management, particularly in assessing the impacts of climate change on water-abundant regions, is crucial for ensuring long-term sustainability. This study investigates the hydrological response of a cold humid basi...
PFAS from a Discrete-Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages [0.03%]
来自离散陆地源的PFAS随着地下水迁移至潮间带地区
Martin A Briggs,Eric A White,Patrick T Scordato et al.
Martin A Briggs et al.
Groundwater transport of per- and polyfluoroalkyl substances (PFAS) from terrestrial sources to marine coastal ecosystems is a topic of growing recognition, though with few published field studies. Furthermore, most research on PFAS fate an...

Preferential flow is common in the vadose zone of bedrock aquifers. Rapid film flow down fracture walls and free-fall flow down open vertical fractures produce velocities that are commonly in the range 10-4 to 10-1 m/s. ...
