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.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

Lower Abundance of Young‐of‐the‐Year Fish in Alpine Rivers Affected by Hydropeaking: An Austrian Field Study

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Rapid sub‐daily flow fluctuations caused by hydroelectric power generation (hydropeaking) pose a significant challenge to aquatic ecosystems in Alpine rivers, particularly for young‐of‐the‐year (YOY) fish. Hydropeaking reduces recruitment rates through reduced spawning success and habitat availability and persistence, as well as increased ...

Cross‐Border Land Tenure Detection With Satellite Imagery Data Using Siamese Neural Network: A Deep Learning Approach

Engineering Reports, Volume 8, Issue 4, April 2026.
Vector layer over raster layer. ABSTRACT Land disputes, particularly cross‐border issues, are a significant source of conflict in Ethiopia, where about 80% of the population depends on land‐based livelihoods and agriculture. These disputes significantly affect the rural population, whose primary source of income depends on land.

True Orthophoto Generation from Aerial Frame Images and LiDAR Data: An Update

Remote Sensing, 2018
Image spectral and Light Detection and Ranging (LiDAR) positional information can be related through the orthophoto generation process. Orthophotos have a uniform scale and represent all objects in their correct planimetric locations.

Automated Two-Step Seamline Detection for Generating Large-Scale Orthophoto Mosaics from Drone Images

Remote Sensing
To generate an orthophoto mosaic from a collection of aerial images, the original images are first orthorectified individually using a Digital Surface Model (DSM).
