Measuring, modelling and managing gully erosion at large scales: A state of the art

Earth-Science Reviews, 2021
Soil erosion is generally recognized as the dominant process of land degradation. The formation and expansion of gullies is often a highly significant process of soil erosion.

Quantitative Evaluation of Gully Erosion Using Multitemporal UAV Data in the Southern Black Soil Region of Northeast China: A Case Study

Remote Sensing, 2022
The black soil region of northeast China is experiencing severe gully erosion. The lack of periodic, high-resolution, short–medium-term, annual, and seasonal observations considerably limit the comprehensive understanding of the processes and mechanisms ...

Historical evolution of gully erosion and its response to land use change during 1968–2018 in the Mollisol region of Northeast China

International Soil and Water Conservation Research
Gully erosion is one of the most severe types of land degradation, hindering food production and sustainable agricultural development. However, the historical evolution process and the impact of land use change on gully erosion remain unclear. To address

Determination of future gully erosion risk and its spatially quantitative interpretability of driving factors in regional scale using machine learning algorithms

Geoderma
Gully erosion has already caused severe damage to land production and ecosystem safety. It is pivotal to identify areas sensitive to and at risk from gully erosion for guiding gully erosion prevention and control efforts.

Gully internal erosion triggered by a prolonged heavy rainfall event in the tableland region of China's Loess Plateau

International Soil and Water Conservation Research, 2023
Gully erosion is a severe form of soil erosion, but gully internal erosion processes are poorly understood, especially at the event scale. To investigate gully internal erosion intensity and understand the related gully development mechanism in an ...
