Three decades of ephemeral gully erosion studies

Soil and Tillage Research, 2021
Abstract Although concern for ephemeral gully (EG) erosion has been growing within the research community, knowledge gaps still need to be identified for a state-of-the-art review. This review is based on an extensive search of published literature in the Web of Science database that specifically addressed EG erosion.

Ephemeral gully development in the hilly and gully region of China's loess plateau

Land Degradation & Development, 2023
AbstractEphemeral gully erosion is a significant form of soil erosion that visibly impacts soil productivity and restricts land use. While watersheds are fundamental for controlling soil erosion, past studies have focused on individual ephemeral gully or slope types, which do not fully represent changes in ephemeral gullies at the watershed scale.

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.

Measurement of Ephemeral Gully Erosion

Transactions of the ASAE, 1988
ABSTRACT THE Universal Soil Loss Equation often under-estimates erosion on agricultural fields because it does not account for the loss of soil from ephemeral gullies. However, the development of appropriate predictive methodology along with the understanding of the erosional processes are limited by the difficulty of acquiring adequate data on ...

Tools for Ephemeral Gully Erosion Research

International Symposium on Erosion and Landscape Evolution (ISELE), 18-21 September 2011, Anchorage, Alaska, 2011
Techniques to quantify ephemeral gully erosion have been identified by USDA Natural Resources Conservation Service (NRCS) as one of the gaps in current erosion assessment tools. One reason that may have contributed to this technology gap is the difficulty to quantify changes in channel geometry to assess the amount of erosion from the gully channels ...

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.

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.

A comprehensive review of ephemeral gully erosion models

CATENA, 2020
Abstract Modeling of ephemeral gully (EG) erosion has lagged that of other soil erosion processes despite its major contribution to watershed sediment losses. Several process and semi-empirical based simulation models have been used to assess the occurrence and location of EGs, magnitude of soil losses from EGs, and degradation, aggradation, and ...

Modelling ephemeral gully erosion in small cultivated catchments

CATENA, 2003
This 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.

Annual variation of ephemeral gully erosion in a cultivated catchment

Geoderma, 2021
Abstract Ephemeral gullies (EG) are important erosion features that reduce land productivity and have potential to produce copious amounts of erosion and sediment from fields. Unchecked, they may also develop into classical gullies and damage the land permanently.
