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.

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 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.

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.

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 ...

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 ...
