Simulating Ephemeral Gully Erosion in AnnAGNPS

Transactions of the ASABE, 2007
Ephemeral gully erosion can cause severe soil degradation and contribute significantly to total soil losses in agricultural areas. Physically based prediction technology is necessary to assess the magnitude of these phenomena so that appropriate conservation measures can be implemented, but such technology currently does not exist.

Ephemeral gully erosion in northwestern Spain

CATENA, 2003
This study aimed to describe types of ephemeral gullies and to determine their origin, evolution and importance as sediment sources in A Coruna province (northwest Spain). Ephemeral gullies and/or rills have been measured in a representative sample of medium-textured soils, most prone to crusting, developed over basic schist.

evolution and development of ephemeral gully erosion in hilly and gully region of the Loess Plateau in China

2023
ephemeral gully erosion is a primary mode of soil erosion that is highly visible, affecting soil productivity and restricting land use. Watershed is the basic unit of soil erosion control; existing research has focused on several typical ephemeral gullies or slopes, which do not fully display changes in ephemeral gullies at a watershed scale.

Quantifying interrill and ephemeral gully erosion in a small Sicilian basin interrill and ephemeral gully erosion in a small Sicilian basin

Zeitschrift für Geomorphologie, Supplementary Issues, 2012
applied to document the contribution of rill-interrill erosion over the same area. Ephemeral gully formation occurred seven hydrologic years out of ten, with a frequency corresponding to 70 % of the years covered occurred seven hydrologic years out of ten, with a frequency corresponding to 70 % of the years covered by the survey and to a return period ...

Method to predict cropland ephemeral gully erosion

Catena, 1999
Abstract Erosion of farmland due to concentrated flow is very severe on many unprotected fields across the United States. Small channels can turn into large gullies if not controlled. These small channels are routinely obliterated by tillage of the field and other routine farm operations only to be reformed again.

Influence of Ephemeral Gully Location Prediction on Soil Erosion Estimation

2021
<p>Predicting ephemeral gully (EG) location is essential for erosion modeling because it helps confine portions of the hillslope segment above locations that gully and channel soil loss processes dominate. In the Water Erosion Prediction Project (WEPP), the prediction of EG occurrence location influences the model results by shorting or ...

Spatially Distributed Sheet, Rill, and Ephemeral Gully Erosion

Journal of Hydrologic Engineering, 2015
AbstractEphemeral gully erosion seriously degrades agricultural soils, but few conservation planning tools adequately account for this form of erosion. To address this deficiency, this paper describes a spatially distributed adaptation of version 2 of the Revised Universal Soil Loss Equation and a new ephemeral gully erosion estimator.

Using Google Earth Imagery to Target Assessments of Ephemeral Gully Erosion

Soil Erosion Research Under a Changing Climate, January 8-13, 2023, Aguadilla, Puerto Rico, USA, 2023
HighlightsTested the utility of Google Earth and other imagery to target the location of ephemeral gullies.Developed a targeting methodology and tested it based on a ground truth obtained using a UAV.Quantified the overlap of targeted areas with observed ephemeral gullies.These publicly available sources of imagery had a high degree of success in ...

Rates and predictability of ephemeral gully erosion in two contrasting environments

Géomorphologie relief processus environnement, 1996
Summary Ephemeral gully erosion in agricultural land is an important source of sediment that is frequently being overlooked and not accounted for in soil erosion studies. However, there is field evidence that ephemeral gully erosion is responsible for significant soil losses.
