Predicting ephemeral gully erosion with RUSLER and EphGEE [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Ephemeral gully erosion is not included in predictions made with the Revised Universal Soil Loss Equation, version 2 (RUSLE2). A new distributed application called RUSLER (RUSLE2-Raster) predicts distributed soil loss and its output can be linked with ...

The Use of Stereoscopic Satellite Images to Map Rills and Ephemeral Gullies [PDF]
Remote Sensing, 2015 Accurate mapping and measurement of erosion channels is necessary to accurately estimate the impact of channeled erosion in an area. Field surveys can provide optimal quantitative results, but they are only applicable to small areas.

An Upscaling-Based Strategy to Improve the Ephemeral Gully Mapping Accuracy
LandUnderstanding and mapping ephemeral gullies (EGs) are vital for enhancing agricultural productivity and achieving food security. This study proposes an upscaling-based strategy to refine the predictive mapping of EGs, utilizing high-resolution Pléiades ...

Gully geometry: what are we measuring? [PDF]
SOIL, 2015 Much of the research on (ephemeral) gully erosion comprises the determination of the geometry of these eroded channels, especially their width and depth.

An Exploration of Loess Landform Development Based on Population Ecology Method
ISPRS International Journal of Geo-Information, 2022 The study of gully characteristics is one of the most effective ways to explore the loess landform development in the Loess Plateau of China. However, current studies mostly focus on gullies’ overall characteristics and ignore the different composition ...

Factors controlling the morphology and volume (V)–length (L) relations of permanent gullies in the Northern Ethiopian Highlands [PDF]
, 2013 Small-scale aerial photographs and high-resolution satellite images, available for Ethiopia since the second half of the twentieth century as for most countries, allow only the length of gullies to be determined.

Seasonal surface drainage of sloping farmland : a review of its hydrogeomorphic impacts [PDF]
, 2015 The combination of runoff-generating areas (saturated soils) and overland flow concentration in features such as drainage ditches makes sloping farmland vulnerable to soil erosion.
