Determining ephemeral gully erosion process with the volume replacement method
CATENA, 2015Abstract 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 by preferential flow through a discontinuous soil-pipe
Catena, 2008Abstract 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.

Earth Surface Processes and Landforms, 2006
AbstractA simple field‐based monitoring programme was established in a small catchment (area 4·6 km2) to find the rates of gully erosion in the Siwalik Hills, Nepal. The rates are used to estimate the amount of sediment produced by gully erosion in the catchment.

An experimental study on dynamic processes of ephemeral gully erosion in loess landscapes
Geomorphology, 2011Abstract 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 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.

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 ...

Quantification Studies on Ephemeral Gully Erosion
Ephemeral gullies (EGs) are major contributors to sediment loss and land degradation on cultivated lands. EG is an important linear erosion feature, often occurring at mid-slope position, that can be greatly influenced by upslope and lateral inflow. This study quantified the ephemeral gully erosion influenced by the upslope and lateral inflow, and the ...openaire +1 more source
Monitoring and Estimating Ephemeral Gully Erosion using Field Measurements and GIS
2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010Ephemeral gully (EG) erosion has been recognized as a major source of sediment in agricultural watersheds. Over the past few decades, soil erosion caused by sheet and rill erosion has been studied extensively, and field and watershed-scale models have been used to quantify contributions of sheet and rill erosion. In recent years, many studies have been

Ephemeral gully erosion is an important erosion type in hilly and gully regions of Loess Plateau. While previous studies mainly focused on ephemeral gullies in agricultural land, little is known about the effects of naturally restored grassland on ephemeral gully erosion. In this study, taking the bare ephemeral gullies as the baseline, we conducted in-

Understanding soil‐pipe flow and its role in ephemeral gully erosion
Hydrological Processes, 2011AbstractThe 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 ...
