Revised classification of glaciofluvial landforms in the Finnish sector of the Fennoscandian Ice Sheet

Boreas, EarlyView.
Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

Assessment of seawater intrusion in coastal aquifers by modified CCME-WQI Indicators: Decadal dynamics in North Jiaozhou Bay, China

Ecological Indicators
Seawater intrusion (SWI) poses a growing threat to groundwater sustainability in the northern coastal region of Jiaozhou Bay (NCRJB), China. Quantifying SWI impacts is critical for developing targeted groundwater management strategies.

Hydrogeochemical characterization of the urban coastal aquifers of Napoli (southern Italy): an overview

Acque Sotterranee, 2019
The presence of phenomena of salt water intrusion in aquifers located in coastal urbanized areas, especially depended on the use of groundwater, is a widespread problem in the world.

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

Modelling of Coastal Aquifers of Trivandrum

Procedia Engineering, 2012
AbstractTrivandrum is one of the fastest growing cities of South India. The degree of landscape modification being made along the coastal zone of this city will be reflected in the quantity and quality of the coastal water resources. To combat the present threats, like the excess groundwater extraction and reclamation activities in the coastal regions ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Effect of Groundwater Pumping on Seawater Intrusion in Coastal Aquifers

Journal of Agricultural and Marine Sciences, 2002
Many aquifers around the globe are located in coastal areas and are thus subjected to the seawater intrusion phenomenon. The growth of population in coastal areas and the conjugate increase in human, agricultural, and industrial activities have imposed ...

Predicting Groundwater Hydrochemical Facies in Three Dimensions with Random Forest Classification, USA

Groundwater, EarlyView.
Random forest classification predictions of groundwater hydrochemical facies (HCFs) can be used for multiple purposes, including the mapping of salinity and other groundwater characteristics. Shown on the figure are predictions of HCFs at the water table across the conterminous United States.

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

Groundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Considerations for the Design of Sinusoidal Slug Testing Methods

Groundwater, EarlyView.
Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...
