Managed Aquifer Recharge Operations and Design under Hydrologic Uncertainty

open access: yesGroundwater, EarlyView.
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 ...

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

A novel boundary meshfree method with two kinds of interpolations for spatially varying coefficient orthotropic thermal transfer

open access: yesCase Studies in Thermal Engineering
For thermal exchangers, thermal pads, and thermal sinks for electronics and engines, it is necessary to consider their thermal transfer properties in different directions to ensure the structural stability and reliability in the hightemperature ...

On Spatial Point Processes With Composition‐Valued Marks

open access: yesInternational Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Spatiotemporal Dynamics of Olive Fruit Fly (Bactrocera oleae) Populations in a Mediterranean Olive‐Growing Landscape: An Eight‐Year Study From Samos Island, Greece

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Olive fruit fly (Bactrocera oleae, Rossi) is one of the most significant pests in the Mediterranean olive groves, causing both quantitative and qualitative losses. Understanding its spatial and temporal dynamics is essential for effective and sustainable control of the pest.

Testing E-OBS European high-resolution gridded data set of daily precipitation and surface temperature [PDF]

open access: yes, 2009
Gridded data sets derived through interpolation of station data have a number of potential inaccuracies and errors. These errors can be introduced either by the propagation of errors in the station data into derived gridded data or by limitations in the ...
