Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

A New Hybrid Approach Applying Feature Engineering to Model High Resolution Air Temperature Across Israel

open access: yesInternational Journal of Climatology, EarlyView.
A hybrid modelling framework that applies feature engineering using the KNN model to estimate high‐resolution air temperature across Israel by integrating meteorological and environmental predictors. ABSTRACT The increasing global planetary temperature, combined with rapid urbanisation, underscores the urgent need to evaluate human exposure to air ...

Evaluación y comparación de métodos de interpolación determinísticos y probabilísticos para la generación de modelos digitales de elevación

open access: yesInvestigaciones Geográficas, 2013
Los modelos digitales de elevación (MDE) son la forma más común y eficaz de representar la superficie terres- tre. Desafortunadamente, al igual que la mayoría de la in- formación geográfica en formato digital, los MDE contienen errores de forma inherente,

Characterisation of Drought and Wet Events in the Paraíba do Sul River Basin—Brazil

open access: yesInternational Journal of Climatology, EarlyView.
Trend analysis identified statistically significant reductions in precipitation (at the 5% significance level) at specific pluviometric stations in São Paulo and Rio de Janeiro, while other areas, mainly in Minas Gerais, experienced significant increases in annual and seasonal rainfall, particularly during summer and spring. These significant trends at

Extreme Climate Events in Morocco: Historical Analysis and Future Projections Based on CMIP6 Simulations

open access: yesInternational Journal of Climatology, EarlyView.
Historical observations and bias‐corrected CMIP6 projections reveal intensifying warm extremes, declining cold events and increasingly irregular precipitation patterns across Morocco. Future warming, particularly under SSP5‐8.5, produces an almost linear amplification of heat, aridity and hydrological stress, leading to longer droughts and more intense

Assessment of the Impact of the Deep Wells Utilization on Groundwater Level Decline (2000-2023): A Case Study of Hazarat Sultan District

open access: yesمجلۀ علمی-تحقیقی سمنگان
Groundwater resources, following polar glaciers, are considered the second-largest source of freshwater globally. Monitoring changes in groundwater levels is critically important for sustainable planning and management in any region.

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

Geometric aspects of representation theory for {DG} algebras: answering a question of Vasconcelos

open access: yes, 2017
We apply geometric techniques from representation theory to the study of homologically finite differential graded (DG) modules $M$ over a finite dimensional, positively graded, commutative DG algebra $U$. In particular, in this setting we prove a version
