Groundwater flow numerical model to evaluate the water mass balance and flow patterns in Groundwater Circulation Wells (GCW) with varying aquifer parameters

Acque Sotterranee, 2022
Groundwater Circulation Wells (GCW) can be an effective in-situ remediation option allowing high mass recovery of contaminants in cases where contamination hotspots are located in saturated soil having low hydraulic conductivity.

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

Practical Guidance for Improving Pump‐Test Based Inference of Hydraulic Parameters in Heterogeneous Unconfined Aquifers

Water Resources Research
Hydrogeological modeling relies on scale estimates for relevant hydraulic parameters. To obtain these, pump test data are typically interpreted using methods derived for idealized conditions (such as a spatially homogeneous medium).

Bio‐Based Sodium Alginate Beads Reinforced With Microalgae (Limnospira platensis): Structure–Property Relationships and Controlled Release Potential

Journal of Applied Polymer Science, EarlyView.
Development of sodium alginate beads doped with Limnospira platensis, designed for the gradual release of nutrients and bioactive molecules into soil. The biomaterial combines biodegradability, controlled‐release potential, and microalgal biomass valorization, contributing to reduced nutrient losses through leaching and the development of more ...

Threat of land subsidence to the groundwater supply capacity of a multi-layer aquifer system

Journal of Hydrology: Regional Studies, 2022
Study region: The study area was the Cangzhou area in the central-eastern North China Plain (NCP). Study focus: Compaction of the aquifer system leads to a change in hydraulic parameters, including the storage coefficient and hydraulic conductivity. This

Dark Heritage Prospection ‐ Mapping the Treblinka II Extermination Camp Using a Magnetometer Survey and Integrated Archival Sources

Archaeological Prospection, EarlyView.
ABSTRACT The history of Nazi German extermination camps has, until recently, relied primarily on eyewitness testimony. Very few official documents detailing the facilities survived the war due to the special operation ‘Sonderaktion 1005’, dedicated to hiding their existence and extent.

Estimating streambed and aquifer parameters from a stream/aquifer analysis test

, 2003
The Tamarack State Wildlife Area in eastern Colorado is being investigated as a possible managed recharge project to redirect flows in the South Platte River for water quantity management. Two primary surface water/groundwater interactions exist at Tamarack: (1) between the South Platte River and alluvial aquifer and (2) between backwater sloughs, or ...

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.
