The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...
Gully erosion is one of the important forms of soil degradation especially in semi-arid areas. Gullies are occupying 13 percent of Ilam Province area. This research focused on studying the, topographic threshold of gullies, dominant process of gully initiation and development as well, in agricultural and rangeland land uses. Ilam province with 2 million hac area is located in western Iran. Ilam...
Gully erosion is widespread in central China's ecologically fragile loess plateau. However, research on the monitoring and evaluation of large-scale scarce. Here, we collected 16 pairs Sentinel-1A images from rainy season, spanning April 5-October 26, 2019, subsidence then quantified its results can indirectly reflect intensity largest plateau China, Dongzhiyuan tableland, using small baseline ...
Taking the Quickbird optical satellite imagery of the small watershed of Beiyanzigou valley of Qixia city, Shandong province, as the study data, we proposed a new method by using a fused image of topography with remote sensing imagery (RSI) to achieve a high precision interpretation of gully edge lines. The technique first transformed remote sensing imagery into HSV color space from RGB color s...
The article presents the results of study modern water-erosion processes in Central Belarus territory. mechanisms sheet, gully and river erosion are considered. areas development these established parameters annual drift calculated. contribution each process to dynamics earth's surface relief region under is determined. It shown that lead noticeable negative consequences for environment, disrup...
Introduction Background and objectives Gully erosion is one of the destructive forms of soil erosions that may lead to a considerable volume of soil loss. This erosion type in addition to on-site and off-site effects has an important role in land degradation and forming in some watersheds. In this regard, due to gully erosion in some provinces of Iran such as Hormozgan, Bushehr, Fars, K...
In recent years, gully erosion has caused soil loss, land degradation, and a large sediment yield in the Mollisols northeastern China, threatening agricultural development national food security. Moreover, prediction of remains great challenge owing to difficulty determining suitable environmental indicators identifying best models for predicting prone areas. Therefore, objective this study was...
