Modelling ephemeral gully erosion in small cultivated catchments
Catena, 2003This paper describes a new erosion model to predict the location and volume of ephemeral gullies within the main runoff collector network of agricultural catchments. This model, using an expert-based approach, combines field experiment results and knowledge about erosion processes and agricultural practices.

Assessment of soil losses by ephemeral gully erosion using high-altitude (stereo) aerial photographs
Earth Surface Processes and Landforms, 1999 The objective of this study is to explore in a critical way the potential of high-altitude (stereo) aerial photographs for the assessment of ephemeral gully erosion rates.

Ephemeral gully channel width and erosion simulation technology
Natural Hazards, 2015Concentrated 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 ...

Application of the EGEM model to predict ephemeral gully erosion in Sicily, Italy
Catena, 2005Abstract Recent research has shown the importance of ephemeral gully (EG) erosion in the context of global erosion and, at the same time, the lack of adequate models to estimate it. At present, the ephemeral gully erosion model (EGEM) is the only conceptual model specifically developed for ephemeral gully erosion estimation. The main aim of the paper
