Characteristics and Observation Methods of Gully Gravity Erosion on the Loess Plateau

Gully gravitational erosion is one of the primary erosion types on the Loess Plateau and an important pathway for sediment yield in watersheds. To address the challenges of the complex gravitational erosion process and the difficulty in observation and identification, this study analyzes the environmental conditions, locations, scales, and types of gravitational erosion on the Loess Plateau. Leveraging existing observation technologies and data processing capabilities, a multi-technology integrated observation method for gravitational erosion is developed through the functional synergy of various observation techniques. This method offers broader observation coverage, faster data processing, and higher precision in monitoring processes, providing a scientific basis for soil and water conservation efforts on the Loess Plateau.
