Application of the EGEM model to predict ephemeral gully erosion in Sicily, Italy

Catena, 2005
Abstract 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

An experimental study on dynamic processes of ephemeral gully erosion in loess landscapes

Geomorphology, 2011
Abstract Ephemeral gully erosion is widespread on the Loess Plateau of China. To provide theoretical support for constructing numerical models and soil-water conservation planning, the hydrodynamic characteristics of ephemeral gully flows were studied by laboratory experiments with a physical model.

Ephemeral gully erosion by preferential flow through a discontinuous soil-pipe

Catena, 2008
Abstract Subsurface flow through soil-pipes can contribute to ephemeral gully erosion but these soil-pipes are cut-off when tillage fills in the gully. The objective was to determine the effect of flow through discontinuous soil-pipes on ephemeral gully erosion.

Determining ephemeral gully erosion process with the volume replacement method

Catena, 2015
Abstract Background Ephemeral gully erosion is an important form of hillslope erosion all over the world. It is of high significance to understand its erosion mechanism. Objective A new volume replacement method is proposed to determine ephemeral gully erosion process. Styrofoam particles of hard granules were used to refill the eroded ephemeral

Ephemeral Gully Erosion Advancements within the AnnAGNPS Watershed Simulation Model

2020
<p>Concentrated runoff increases erosion and moves fine sediment and associated agrichemicals from upland areas to stream channels. Ephemeral gully erosion on croplands in the U.S. may contribute more of the sediment delivered to the edge of the field then from sheet and rill erosion.

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.

Analysis of ephemeral gully erosion in small agricultural watersheds in Iowa (USA)

2020
<p>Ephemeral gullies (EG) are linear erosion features located in swales where surface and/or subsurface runoff concentrate during or immediately after rainfall events. As its name states, EGs are temporary because they are easily filled by conventional machinery, but when filled they reform if the area is not appropriately ...

Understanding soil‐pipe flow and its role in ephemeral gully erosion

Hydrological Processes, 2011
AbstractThe role of soil pipeflow in ephemeral gully erosion is not well understood. Experiments were conducted on continuous soil pipes to better understand the role of internal erosion of soil pipes and its relation to ephemeral gully development. Soil beds of 140 cm length, 100 cm width and 20 cm depth had a single soil pipe of different initial ...

Ephemeral gully erosion in concentrated flow channels induced by rainfall and upslope inflow on steep loessial slopes

Land Degradation and Development, 2021
Ephemeral gullies (EGs) play a crucial role in hydrological connectivity, soil erosion, and land degradation. However, little research has focused on flow hydraulics in concentrated flow channels and their effects on EG erosion on steep loessial slopes ...
