The Effects of Tidal Forcing on Nutrient Fluxes in the Tidal, Freshwater James River Estuary, VA [PDF]

open access: yes, 2016
A 12-month study (January to December 2015) focused on the effects of tidal forcing on nutrient fluxes in the tidal, freshwater segment of the James River Estuary (JRE). Discrete sampling of nutrient chemistry and continuous monitoring of tidal discharge

A New European Slope Length and Steepness Factor (LS-Factor) for Modeling Soil Erosion by Water [PDF]

open access: yes, 2015
The Universal Soil Loss Equation (USLE) model is the most frequently used model for soil erosion risk estimation. Among the six input layers, the combined slope length and slope angle (LS-factor) has the greatest influence on soil loss at the European ...

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 ...

Modeled Seed Accumulation Patterns Explain Spatial Heterogeneity of Shrub Recruitment Within the Taiga‐Tundra Ecotone

open access: yesJournal 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 ...

Landslide inventory validation and susceptibility mapping in the Gerecse Hills, Hungary

open access: yesGeo-spatial Information Science, 2021
Landslides pose a threat to property both in the populated and cultivated areas of the Gerecse Hills (Hungary). The currently available landslide inventory database holds the records from many sites in the area, but the database is out-of-date.
