Using geostatistical and deterministic modelling to identify spatial variability of groundwater quality [PDF]
Desert, 2019 The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy
International Journal of Climatology, EarlyView.This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania
International Journal of Climatology, EarlyView.Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.

Structural Concrete, EarlyView.Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...
