Earth 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 ...

Scale-Optimized Surface Roughness for Topographic Analysis
Geosciences, 2019 Surface roughness is a terrain parameter that has been widely applied to the study of geomorphological processes. One of the main challenges in studying roughness is its highly scale-dependent nature.

Geomorphometry: Today and Tomorrow [PDF]
, 2018 This paper summarizes the current state-of-the-art in geomorphometry and describes the innovations that are close at hand and will be required to push digital terrain modeling forward in the future. These innovations will draw on concepts and methods from computer science and the spatial sciences and require greater collaboration to produce “actionable”

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.Abstract Arctic shrub productivity trends display variability at multiple spatial scales. Fine‐scale studies have generally observed the greatest shrub expansion in landscape positions that accumulate water and nutrients. While considerable work has focused on the mediating effect of these resources on growth responses to warming, less is known about ...

Wood jam mobility in a morphologically active river in northern Chilean Patagonia
Earth Surface Processes and Landforms, Volume 50, Issue 3, 15 March 2025.This study examined post‐eruption wood jam mobility and channel changes in the Blanco River. Floodplain collapses led to large sediment yields. High wood jam mobility rates were reported. Larger, less compact wood jams persist in stable areas; new and missing jams are smaller and linked to deposition and erosion, respectively.

Hungarian Geographical Bulletin, 2014 The availability of global coverage digital surface models (like ASTER GDEM or SRTM) and the variation of fused models based on these (like EU-DEM) still has a great impact on scientific researches, as they provides a fairly good base dataset with a low ...

Global Ecology and Biogeography, Volume 33, Issue 11, November 2024.ABSTRACT Aim Heterogeneity of the Earth's abiotic surface and subsurface (geodiversity) is increasingly recognised as an important driver of biodiversity. Theoretically, species' traits should match to abiotic conditions in the local environment. Here, we test this for the first time at a continental extent by analysing the relationships between ...

Geomorphometry 2020 - Conference proceedings
, 2020 Geomorphometry is the science of quantitative land surface analysis. It gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis, terrain morphometry or terrain analysis and land ...
