Application of the GIS in the Determination of Susceptible Areas to Gully Erosion Using the Analytic Network Process (ANP) [PDF]
پژوهشهای آبخیزداری, 2018 Gully erosion is types of water erosion that its occurrence and development lead to the loss of fertile agricultural soil, depletion of soil and groundwater. The objectives of this study were to investigate gully erosion and determine the sensitive areas

Gully Erosion Susceptibility Mapping in Highly Complex Terrain Using Machine Learning Models
ISPRS Int. J. Geo Inf., 2021 Gully erosion is the most severe type of water erosion and is a major land degradation process. Gully erosion susceptibility mapping (GESM)’s efficiency and interpretability remains a challenge, especially in complex terrain areas.

Geofluids, 2022 Gully erosion is the major soil erosion type in the black soil region of Northeast China. However, studies on multifactor synthesis at a large scale and on the driving mechanism of spatial differentiation are still relatively lacking for gully erosion in

Intersecting views of gully erosion in South Africa
Earth Surface Processes and Landforms, 2022 Gully erosion is an environmental problem recognized as one of the worst land degradation processes worldwide. Insight into regional gully perturbations is required to combat the serious on‐ and off‐site impacts of gullying on a catchment management ...

A multi-hazard map-based flooding, gully erosion, forest fires, and earthquakes in Iran
Scientific Reports, 2021 We used three state-of-the-art machine learning techniques (boosted regression tree, random forest, and support vector machine) to produce a multi-hazard (MHR) map illustrating areas susceptible to flooding, gully erosion, forest fires, and earthquakes ...

Intensive landscape-scale remediation improves water quality of an alluvial gully located in a Great Barrier Reef catchment [PDF]
Hydrology and Earth System Sciences, 2021 Gully erosion can be a major disruptor to global fluvial sediment budgets. Gully erosion in the catchments of the Great Barrier Reef is attributed to ∼40 % of fine suspended sediment pollution to the freshwater and marine ecosystems downstream ...

ISPRS International Journal of Geo-Information, 2021 Soil erosion is one of the most challenging environmental issues in the world, causing unsustainable soil loss every year. In South Africa, several episodes of gully erosion have been documented and clearly linked to the presence of Quaternary colluvial ...
