Systematic review on gully erosion measurement, modelling and management: Mitigation alternatives and policy recommendations

Abstract

The problem of “gully erosion” is one of the severe “natural hazards” associated with large‐scale land degradation in various parts of the world. Therefore, accurate modelling is one of the crucial responsibilities in this study on gully erosion. But there are still a lot of gaps in our knowledge of gully erosion and its consequences. Particularly at the regional to continental scale, this is true. Gullying is hence often forgotten about in regulation and watershed management plans. The scientific community is becoming increasingly interested in gully erosion, yet many information gaps still need to be filled. In this research, we are trying to fill the mentioned gap with the help of the existing literature. Most gully erosion research has been done to estimate the susceptible zones and ultimately select the best model. In this research, a test application has been made by considering some important models. Then the “vulnerability assessment” was done with the help of “gully erosion, climate‐induced chemical weathering and socio‐economic variables” at the village level. The village‐level information has been used to determine the vulnerability in this region. This information is beneficial for future researchers to conduct gully erosion research in various parts of the world.
