Gully erosion is well-developed in the Jinsha dry-hot valley region, which has caused serious soil losses. volume regarded as an effective indicator that can reflect development intensity of gully erosion, and evolutionary processes gullies be predicted based on dynamic variation volume. Establishing prediction model essential to determine accurately conveniently. Therefore, this work, empirica...
Gully erosion is known to affect soil productivity, and limit land use in many parts of the world. To assess susceptibility soils gully erosion, triggering factors must be analyzed. A simulation development over time was implemented Python – GIS modules based on topographic characteristics study area, properties, measured runoff. The results show that developed allow a successful data preparati...
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...
Gully Erosion Classification in Kermanshah Province using Relative Similarity Analysis with Morphometric and Soil Auxiliary Variables
We found that craters in the mid-latitudes of Mars possess a marked asymmetry, which is linked with the occurrence of gullies. We also found that a prerequisite for gully formation is the occurrence of steep slopes. The analysis was performed in three areas with elevation data from the High Resolution Stereo Camera (HRSC) on-board Mars Express. Figure 1: MOLA global map with our study sites mar...
Exploring the phenomenon of surface cracks and abnormal ground behavior during coal mining under gully landforms, laboratory physical similarity simulation models were established to study movement characteristics laws working faces different methods landforms. The results indicate that in cases when a roadway is situated below top slope, corresponding deformation surrounding rock aggravated by...
Gully erosion is known as one of the most important and destructive forms of land degradation, and the loss of soil throughout the world. As estimation of soil volume loss and understanding the economic costs of soil erosion are of great importance; this study has been carried out to calculate the amount of soil volume loss due to gully erosion and estimate its economic cost in Ghazeian watersh...
