FEM–DEM modeling of pseudo static experiments on scaled‐down rockfill dams with dry stone pitching
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 5, Page 759-792, 10 April 2023., 2023 Abstract Rockfill dams with stone pitching are specific hydraulic structures generally built in the early XXth century where stones used to be hand‐placed without mortar to constitute the upward and downward dam faces. Few studies have been carried out to quantify the specific and critical role of the pitching in the dam stability against both static ...

Mapping rill soil erosion in agricultural fields with UAV‐borne remote sensing data
Earth Surface Processes and Landforms, Volume 48, Issue 3, Page 596-612, 15 March 2023., 2023 An automatic workflow is introduced to map erosion rills at field scale in UAV‐photogrammetry derived digital elevation models by considering topographic features and machine learning. Abstract Soil erosion by water is a main form of land degradation worldwide.

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 3, March 2023., 2023 Abstract Fault zones are usually composed of a granular gouge, coming from the wear material of previous slips, which contributes to friction stability. When considering a mature enough fault zone that has already been sheared, different types of infill materials can be observed, from mineral cementation to matrix particles that can fill the remaining ...

Journal of Flood Risk Management, Volume 16, Issue 1, March 2023., 2023 Abstract Urban roads are especially vulnerable to waterlogging during rainfall events. Assessments of urban road waterlogging risk are critical for disaster prevention and mitigation. This paper presents a rapid and practical approach for assessing the risk of urban road waterlogging based on a source–pathway–receptor concept and a digital elevation ...
