Analyzing high resolution topography for advancing the understanding of mass and energy transfer through landscapes: A review

open access: yes, 2015
International audienceThe study of mass and energy transfer across landscapes has recently evolved to comprehensive considerations acknowledging the role of biota and humans as geomorphic agents, as well as the importance of small-scale landscape ...

By land, water, and air: an evaluation of the impact of embankment setbacks and two-stage channel design on flood characteristics of the upper River Nith [PDF]

open access: yes, 2023
River channelisation is a method of hard engineering that laterally constrains and straightens a river, with the twofold aims of increasing a river’s hydraulic efficiency and minimising land loss due to floodrelated erosion.

Quantifying river morphological changes using multi‐satellite observations and in situ measurements

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
This study integrates optical, radar and altimetry satellite data with river gauge measurements to estimate periodically submerged riverbed topography and quantify morphological change. By linking how often water covers the riverbed with water‐level variations, erosion and deposition patterns are mapped across a reach of Jamuna River.

Dynamic restoration and the impact of native versus invasive vegetation on coastal foredune morphodynamics, Lanphere Dunes, California, USA [PDF]

open access: yes, 2022
The Lanphere Dunes, part of the Humboldt Bay National Wildlife Refuge, has been the focus of foredune restoration efforts since the 1980s. Efforts have centred around removal of an invasive European beach grass species, Ammophila arenaria, introduced in ...

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 ...

The impact of riparian vegetation on bank erosion during extreme weather events

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 10, August 2025.
This study uses lidar and aerial imagery to investigate relationships between riparian vegetation cover and bank erosion during extreme weather events. Bank erosion was related to riparian vegetation cover/removal and river geomorphology (notably radius of curvature and inner/outer bends).

Quantifying streambank erosion: A comparison of physical surveys, aerial imagery and UAS LiDAR surveys

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Four methods were used to quantify short‐term (1–2 years) reach‐wide streambank erosion rates along three low‐order streams in western Virginia: (1) bank height and cross‐section (XS) surveys, (2) bank height and top of bank (TOB) surveys, (3) bank height survey and aerial imagery analysis and (4) DEM of Difference (DoD) using UAS LiDAR with channel ...

Geomorphic Change Detection in an Incised Montane Meadow Stream Channel [PDF]

open access: yes, 2023
Sierran montane meadows are dynamic wetland systems that provide important ecosystem functions and services but have been impacted by extensive land-use and widespread degradation often resulting in stream channel incision.

The hydro‐geomorphic effects of wooden leaky barriers in a steep headwater stream

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
The hydro‐geomorphic effects of 16 in‐stream wooden leaky barriers (LBs) were monitored over three years. The effects on velocities, inundation extent and celerity were limited. Localised backwater deposition initiated by LBs reduced velocities and increased inundation. A reach‐wide net deposition response of 3.49 ± 0.36 m3 was observed.

Geomorphic changes after the 2021 Central European flood in the Ahr Valley by LiDAR-based differences

open access: yesEnvironmental Sciences Europe
Background In July 2021, destructive floods in Western Europe were triggered by enormous precipitation rates related to a low-pressure system named "Bernd." These catastrophic events led not only to major damage to infrastructure, severe economic losses,
