Building‐Scale Flood Hazard Modelling for Risk Assessment of Cultural Heritage
Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.ABSTRACT Flooding is among the most frequent natural hazards threatening cultural heritage sites, yet current flood hazard studies often operate at urban or regional scales. While building‐scale damage models exist, they generally rely on flood depth inputs from large‐scale inundation models, inputs that may fail to capture the internal complexity of ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR
River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Ecological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.Maps annotated with the height and distance of surrounding landscape features were provided to surveyors estimating bird flight height during ornithological vantage point surveys. Our results suggest that annotated maps can significantly reduce variability in the surveyors' estimates, improving accuracy and collision risk predictions.

A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters [PDF]
, 2015 The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part
