Temporal Evolution of Coastal Cliffs From Weekly to Interannual Timescales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract A 7‐year coastal cliff erosion record, developed from 320 ∼weekly LiDAR surveys of a 2.3 km‐long cliff in southern California, is used to examine the cliff geomorphological response to the variability of environmental forcing (water level, waves, rain, and groundwater) from weekly to interannual timescales at different cliff elevations.

RADIOMETRIC CALIBRATION OF MULTI-WAVELENGTH AIRBORNE LASER SCANNING DATA [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Airborne laser scanning (ALS) is a widely used technique for the sampling of the earth's surface. Nowadays a wide range of ALS sensor systems with different technical specifications can be found.

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

HIGH RESOLUTION AIRBORNE SHALLOW WATER MAPPING [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
In order to meet the requirements of the European Water Framework Directive (EU-WFD), authorities face the problem of repeatedly performing area-wide surveying of all kinds of inland waters. Especially for mid-sized or small rivers this is a considerable

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Modelling forest dynamics using integral projection models and repeat lidar

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 479-493, June 2026.
Forests are facing increasing pressure from climate change and disturbance, yet linking individual tree trajectories to whole‐forest outcomes remains a major challenge. Our study integrates repeat airborne lidar with an Integral Projection Model to analyse demographic processes at the landscape scale.

Evolution of Soil Surface Roughness and Its Influence on Flow Pathways and Sediment Connectivity

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Soil surface roughness (RR) and its spatiotemporal variations are important for understanding soil erosion process, but how the erosion‐induced evolution of RR affects flow pathways and sediment connectivity patterns remains unclear. This study used high‐resolution topographic data sets from a long‐term rainfall simulation experiment in semi ...

A terrestrial laser scanning‐based workflow for component‐wise estimation of individual tree above‐ground biomass

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1938-1949, June 2026.
Abstract Accurate estimation of individual tree above‐ground biomass (AGB) and its component‐wise allocation is crucial for advancing ecological research and forest management. However, current biomass estimation methods, such as destructive sampling and allometric equation–based approaches, face limitations in both operational efficiency and cost ...

Alois Riegl (1858-1905) Le culte moderne de Riegl

Revue germanique internationale, 1994
Membre de la première école de Vienne, inspirateur de Walter Benjamin, Alois Riegl a été canonisé par l’histoire de l’art. Pourtant l’auteur de l’Industrie artistique à la fin de l’époque romaine et des Questions de style reste à certains égards très dépendant d’un hégélianisme épigonal.
