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 ...

Testing the Ephemeral Gully Erosion Model (EGEM) for two Mediterranean environments

Earth Surface Processes and Landforms, 2001
Few models can predict ephemeral gully erosion rates (e.g. CREAMS, EGEM). The Ephemeral Gully Erosion Model (EGEM) was specifically developed to predict soil loss by ephemeral gully erosion. Although EGEM claims to have a great potential in predicting soil losses by ephemeral gully erosion, it has never been thoroughly tested.

Ephemeral gully erosion in southern Navarra (Spain)

CATENA, 1999
Abstract Ephemeral gully erosion is a common type of water erosion in the loamy soils formed on the Miocene Marls of southern Navarra. A study has been conducted to describe the different types of ephemeral gullies and to determine their origin, evolution and importance as sediment sources.

Using a landform evolution model to study ephemeral gullying in agricultural fields: the effects of rainfall patterns on ephemeral gully dynamics

Earth Surface Processes and Landforms, 2017
AbstractWater driven soil erosion is a major cause of land degradation worldwide. Ephemeral gullies (EGs) are considered key contributors to agricultural catchment soil loss. Despite their importance, the parameters and drivers controlling EG dynamics have not been adequately quantified.

Geomorphic threshold conditions for ephemeral gully incision

Geomorphology, 1996
Abstract Ephemeral gully erosion in cultivated land is an important source of sediment that is frequently being overlooked and not accounted for in soil erosion studies. Furthermore, little is known about the factors controlling ephemeral gully erosion.

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.

Ephemeral gully channel width and erosion simulation technology

Natural Hazards, 2015
Concentrated surface runoff, such as associated with ephemeral gully channels, increases erosion and transfers fine sediment and associated agrichemicals from upland areas to stream channels. Ephemeral gully erosion on cropland may contribute up to 40 % or more of the sediment delivered to the edge of agricultural fields, significantly threatening the ...

Prediction of concentrated flow width in ephemeral gully channels

Hydrological Processes, 2002
AbstractEmpirical prediction equations of the form W = aQb have been reported for rills and rivers, but not for ephemeral gullies. In this study six experimental data sets are used to establish a relationship between channel width (W, m) and flow discharge (Q, m3 s−1) for ephemeral gullies formed on cropland. The resulting regression equation (W = 2·51

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 ...
