Gully erosion spatial modelling - Role of machine learning algorithms in selection of the best controlling factors and modelling process

, 2020
This investigation assessed the efficacy of 10 widely used machine learning algorithms (MLA) comprising the least absolute shrinkage and selection operator (LASSO), generalized linear model (GLM), stepwise generalized linear model (SGLM), elastic net ...

Quantifying gully erosion in the black soil region of Northeast China by long-term RTK GPS survey

International Soil and Water Conservation Research
Gully erosion is a severe form of soil erosion but has not been studied adequately as other types like interrill and rill erosion. Commonly used remote sensing approaches can only deal with the areal characteristics of gullies while the gully erosion ...

Hydrogeomorphic processes affecting dryland gully erosion: Implications for modelling

, 2019
Gullies contribute high sediment loads to receiving waters and significantly degrade landscapes. In drylands, low annual rainfall and resultant poor ground cover, coupled with high-intensity storms and dispersive soils, predispose these landscapes to ...

Badland and gully erosion in the Karoo, South Africa

, 2008
To the European eye, the Karoo is an ancient landscape untouched by major climate change or glaciation and evolving through erosional processes since deposition of Jurassic rocks, uplift, and the break up of Gondwana about 180 million years ago (McCarthy
