Using LiDAR‐Based DEM Elevation Difference Calculations to Estimate Net Streambank Erosion in an Iowa River, USA

open access: yesRiver Research and Applications, Volume 41, Issue 7, Page 1418-1426, September 2025.
ABSTRACT Streambank erosion is an important source of sediment to river systems but is difficult to quantify at watershed scales. In this study, high‐resolution Light Detection and Ranging (LiDAR) measurements collected from 2009 and 2020 were used to quantify the difference in land surface elevation that occurred along the fourth and fifth‐order ...

A Discrete Element Method–Based Energetic Approach to Model Two‐Dimensional Fatigue Crack Propagation

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 5, Page 1420-1436, 10 April 2025.
ABSTRACT In this work, a fatigue crack propagation model is proposed using the two‐dimensional discrete element method (DEM). The challenge lies in describing the small progressive fatigue crack growth within a single cycle, which is typically much smaller than the size of the smallest particles, making it difficult to continuously capture the loss of ...
