CHARACTERISTICS OF ACTIVELY ERODING EPHEMERAL GULLIES IN AN EXPERIMENTAL CHANNEL

Transactions of the ASAE, 2000
The formation of ephemeral gullies can significantly increase soil losses from agricultural lands and severely impact farm productivity, yet few data exist on the physical characteristics of actively eroding gullies. The objectives of the current study were to examine the time variation of gully morphology and sediment load in response to a range of

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.

Gully erosion in the Siwalik Hills, Nepal: estimation of sediment production from active ephemeral gullies

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.

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 ...

Generation, transport and preservation of armoured mudballs in an ephemeral gully system

Geomorphology, 2008
Abstract Armoured mudballs have been reported from modern fluvial catchments and preserved in ancient (Quaternary and older) sedimentary sequences. Despite many descriptions of mudballs in the literature there is little systematic analysis of their physical properties, genesis, transport and deposition within alluvial sequences.

Rates and predictability of ephemeral gully erosion in two contrasting environments

Géomorphologie relief processus environnement, 1996
Summary Ephemeral gully erosion in agricultural land is an important source of sediment that is frequently being overlooked and not accounted for in soil erosion studies. However, there is field evidence that ephemeral gully erosion is responsible for significant soil losses.

Effect of naturally restored grassland on the ephemeral gully erosion in the loess hilly and gully region.

Ying yong sheng tai xue bao = The journal of applied ecology, 2019
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-
