Effect of foundation stiffness on the fragility curves of a concrete gravity dam under far-field ground motions

open access: yesResults in Engineering
The finite element method is used to model the dam-reservoir-foundation interaction system, with the Latyan dam in Iran as a case study. A comprehensive concrete damage plastic model is employed to simulate the nonlinear behavior of concrete ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis

open access: yesComputer Graphics Forum, EarlyView.
In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40

Insights for conservation from the Ecological Knowledge Games project

open access: yesConservation Biology, EarlyView.
Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Bovines, buffers and barriers: A social scientific perspective on rewilding in the Kavango‐Zambezi Transfrontier Conservation Area

open access: yesConservation Science and Practice, EarlyView.
Rewilding is often summarized with the three C's of Carnivores, Cores and Corridors. In this essay we propose a complementary perspective that focuses on the three B's of Bovines, Buffers and Barriers. This complementary perspective draws attention to rewilding as a social (rather than only ecological) challenge and is illustrated with insights from ...
