An approach for real-time monitoring of hydrological risk hotspots during extreme rainfall events

Geomatics, Natural Hazards & Risk
Real-time monitoring of hydrological risk hotspots during extreme rainfall events is limited by certain challenges. Here, we introduce a new approach for tracking such hotspots across large areas in real time.

Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.

Configurational Energy as a Microstructural Descriptor of Failure Precursors in 2D Frictional Granular Materials

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Localized deformation in dense granular materials, often culminating in the formation of shear bands, is a key failure mechanism in geotechnical and material systems. However, predicting the onset of such localization remains a fundamental challenge due to the system's inherent inelasticity and microstructural complexity.

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Populism and policy capacity: Evidence from an opposition municipality in Istanbul

Public Administration and Development, EarlyView.
Abstract Despite achievements in its conceptual rigor, policy capacity still represents a relatively depoliticized concept that fails to sufficiently consider the ways in which politics plays a role in its creation, mobilization, or decay. This article seeks to contribute to this debate by investigating the impact of populism on policy capacity, the ...

Assessment of the effects of training data selection on the landslide susceptibility mapping: a comparison between support vector machine (SVM), logistic regression (LR) and artificial neural networks (ANN)

, 2018
Landslide is a natural hazard that results in many economic damages and human losses every year. Numerous researchers have studied landslide susceptibility mapping (LSM), each attempting to improve the accuracy of the final outputs.
