Gully erosion is one of the most complicated and destructive forms of water erosion. In order to prevent this erosion, the important factors advancing gully head must be recognized. Nowadays, several models have been proposed in measuring gully head advancement and identifying the severity of erosion. These models must be calibrated for each country to see whether they are applicable or not. So...

The effects of climate change on future water availability and water quality are not well understood, making the development of watershed management plans difficult for decision-makers. Agricultural best management practices (BMPs) are commonly implemented to mitigate non-point source (NPS) pollution, but future effectiveness is unknown due to climate change. To address these problems, the foll...

Traditional methods to evaluate flood risk generally focus on heavy storm events as the principal cause of flooding. Conversely, fault tree analysis is a technique that aims at modelling all potential causes of flooding. It quantifies both overall flood probability and relative contributions of individual causes of flooding. This paper presents a fault model for urban flooding and an applicatio...

Abstract Loess Plateau provides a broad growing environment for crops. However, due to the loose soil, soil erosion is serious. Gully Consolidation and Highland Protection key work in construction of ecological civilization Plateau. Using method simulating Protection, terrain conditions are changed, hydrological model used simulate change before after ditch head landfill. In this paper, Yangjia...

Gully erosion susceptibility (GES) maps are essential for managing land resources and control. Choosing the optimal horizontal resolution in GES mapping is a challenge. In this study, complex loess hilly area on Chinese Loess Plateau was tested using two machine learning algorithms. Unmanned aerial vehicle (UAV) images with 9 cm GNSS RTK field-measured data were employed as base datasets, 11 fa...

The topographic threshold is based on the power relationship between area and slope widely applied in gully-erosion research; however, this requires further testing. Accordingly, Alamarvdasht Lamerd Fadagh Larestan regions Fars Province, Iran, were selected as case studies to explore for gullies. Thirty active gullies identified each study during field surveys, data describing land use cover, d...

The Sichuan–Tibet Railway crosses through the largest maritime glacier region in China. A large number of moraines formed after rapid glacial retreat caused by climate warming. Moraines could induce frequent geological hazards that seriously threatened safe construction and operation railway. Accordingly, this have become a new challenging research topic with respect to formation hazards. Using...
