Building Local Resilience Potential on a Day‐to‐Day Basis: The Influence of Stakeholder Dynamics and Contextual Factors

open access: yesJournal of Contingencies and Crisis Management, Volume 34, Issue 1, March 2026.
ABSTRACT The aim of this study is to clarify how and under what conditions an area builds (or fails to build) its resilience potential on a day‐to‐day basis. In this way, it contributes to a better understanding of the influence of the antecedents of resilience (e.g., undesirable events, capacity of stakeholders).

Assessment of Road Crossings for Improving Migratory Fish Passage in the Winnicut River Watershed [PDF]

open access: yes, 2009
This report summarizes the results of a river continuity assessment focused on roadstream crossings. The Winnicut River is the site of a restoration project that removed a head-of-tide dam and resulted in the only free-flowing major tributary to the ...

Effect of Concrete Swelling on the Equilibrium and Displacements of an Arch Dam [PDF]

open access: yes, 2011
The Kariba dam is undergoing concrete expansion as a result of an alkali-aggregate reaction. The model adopted to simulate the process is explained in the paper; it is based on the model first proposed by Ulm et al, as later modified by Saouma and ...

Dam seepage analysis based on artificial neural networks: the hysteresis phenomenon [PDF]

open access: yes, 2013
Seepage flow measurement is an important behavior indicator when providing information about dam performance. The main objective of this study is to analyze seepage by means of an artificial neural network model.

Predicting Seismic Debris Distributions of Collapsed Unreinforced Masonry Structures Through Physics Engines and Machine Learning Algorithms

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
Unreinforced masonry (URM) structures are widespread worldwide, particularly in older urban districts. However, URM buildings—particularly those constructed before the introduction of modern building codes—are highly vulnerable to seismic hazard, and prone to experiencing local and/or global failures when subjected to significant horizontal shaking ...

Dynamic Analysis of Concrete Arch Dam due to Earthquake Force [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
A gravity dam with concrete is a vast construction that keeps a large volume of water on its upstream side, and its ability to withstand seismic vibrations is critical.

Implementing Bayesian network models using expert elicitation for instream barrier assessment

open access: yesJournal of Applied Ecology, Volume 63, Issue 2, February 2026.
We have demonstrated that BN modelling and expert knowledge can be used for assessing the likelihood of fish passage where empirical data are lacking or sparse. The probabilistic framework is consistent with the need to reflect that many structures are partial barriers to fish movement and cannot be represented accurately in a binary pass/fail ...
