Risk-based flood protection planning under climate change and modeling uncertainty: a pre-alpine case study [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2018
Planning authorities are faced with a range of questions when planning flood protection measures: is the existing protection adequate for current and future demands or should it be extended? How will flood patterns change in the future? How should the

Seismic reliability assessment of classical columns subjected to near-fault ground motions [PDF]

open access: yes, 2013
A methodology for the performance-based seismic risk assessment of classical columns is presented. Despite their apparent instability, classical columns are, in general, earthquake resistant, as proven from the fact that many classical monuments have ...

Probabilistic prediction of daily fire occurrence in the Mediterranean with readily available spatio-temporal data

open access: yesiForest - Biogeosciences and Forestry, 2017
The prediction of wildfire occurrence is an important component of fire management. We have developed probabilistic daily fire prediction models for a Mediterranean region of Europe (Cyprus) at the mesoscale, based on Poisson regression.

Impact-Detection Algorithm That Uses Point Clouds as Topographic Inputs for 3D Rockfall Simulations

open access: yesGeosciences, 2021
Numerous 3D rockfall simulation models use coarse gridded digital terrain model (DTM raster) as their topography input. Artificial surface roughness is often added to overcome the loss of details that occurs during the gridding process. Together with the

Quantification of climate change impact on dam failure risk under hydrological scenarios: a case study from a Spanish dam [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2019
Dam safety is increasingly subjected to the influence of climate change. Its impacts must be assessed through the integration of the various effects acting on each aspect, considering their interdependencies, rather than just a simple accumulation of ...
