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 ...

Spline quasi‐interpolation in the Bernstein basis and its application to digital elevation models
Mathematical Methods in the Applied Sciences, Volume 46, Issue 2, Page 1687-1698, 30 January 2023., 2023 A nonstandard low‐cost spline approximation method for approximating bivariate functions is constructed. It is applied for Digital Elevation approximation and then its accuracy in the downscaling process is studied.

A Comprehensive Assessment of Floodwater Depth Estimation Models in Semiarid Regions
Water Resources Research, Volume 58, Issue 11, November 2022., 2022 Abstract Simple models continue to be important for continental‐scale floodwater depth mapping due to the prohibitively expensive cost of calibrating and applying hydrodynamic models. This paper investigates the accuracy of three simple models for floodwater depth estimation from remote sensing derived water extent and/or Digital Elevation Models (DEMs)
