Dry Means Green—Using ALS LiDAR DEM to Determine the Geomorphological Reaction of a Large, Untrained, European River to Summer Drought (the Vistula River, Warsaw, Poland)

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Using ALS LiDAR DEM, we study the geomorphology and geoecology of fluvial islands in the channel of braided river, which was affected by summer drought.

Morphodynamic change analysis of bedforms in the Lower Orinoco River, Venezuela [PDF]

Proceedings of the International Association of Hydrological Sciences, 2018
The Orinoco River has the third largest discharge in the world, with an annual mean flow of 37 600 m3 s−1 at its outlet to the Atlantic Ocean. Due to the presence of the Guiana Shield on the right bank, the lower reach of the Orinoco has a plan form ...

Quantitative Analysis of Anthropogenic Morphologies Based on Multi-Temporal High-Resolution Topography

Remote Sensing, 2019
Human activities have reshaped the geomorphology of landscapes and created vast anthropogenic geomorphic features, which have distinct characteristics compared with landforms produced by natural processes. High-resolution topography from LiDAR has opened

Incorporating the effect of ALS-derived DEM uncertainty for quantifying changes due to the landslide in 2011, Mt. Umyeon, Seoul

GIScience & Remote Sensing, 2020
The landslide, which occurred at Umyeon mountain (Mt. Umyeon) in Seoul, Korea in 2011, was a prime example that raised awareness about the landslide in the highly urbanized area.

Monitoring Coastal Geomorphic Change and Sediment Transport Using Kite Aerial Photography (KAP) and Structure-from-Motion (SfM) Photogrammetry

Remote Sensing
Coastal areas are particularly suitable study sites for kite aerial photography (KAP) surveys because of consistent wind and open space. This study uses KAP surveys conducted in January, March, June, August, and October 2025, combined with Structure from

Integrating hydro-geomorphological adjustments into flood mapping for enhanced risk assessment

Geoenvironmental Disasters
Accurate flood risk assessment is essential for effective risk management, especially as extreme rainfall trends have increased flood frequency and inundation globally. However, rainfall data alone often becomes insufficient in dynamic floodplains, where

UAV-based evaluation of morphological changes induced by extreme rainfall events in meandering rivers.

PLoS ONE, 2020
Morphological changes, caused by the erosion and deposition processes due to water discharge and sediment flux occur, in the banks along the river channels and in the estuaries.

Response to comment by Daley et al., on “Assessing gully erosion and rehabilitation using multi temporal LiDAR DEMs: Case study from the Great Barrier Reef catchments, Australia”

International Soil and Water Conservation Research
Daley et al. (2023a) argue that at least 10–15 years apart Digital Elevation Model (DEM) derived DEMs of Difference (DoD) surveys are needed to detect reliable geomorphic change within the gullied landscapes of the Great Barrier Reef, Australia.

Investigation of Erosion Processes on the Slope-Gully System Using 3D Laser Scanning

Shuitu baochi yanjiu, 2023
In order to explore the soil erosion process of in-situ slope-gully systems, five runoff scouring experiments were undertaken on a slope-gully system plot established on a natural slope of a small catchment(i.e.
