Comment on "Towards improved USLE-based soil erosion modelling in India: A review of prevalent pitfalls and implementation of exemplar methods" by Majhi et al. (2021), Earth-Science Reviews 221, 103786

The authors did an excellent job of analyzing the USLE-based soil erosion surveys conducted in India and outlining the causes and mistakes encountered when estimating the USLE erosion factors in these studies. They're analysis reveals the flaws in previous studies that used USLE-based models to estimate soil erosion, which is precisely the type of work we need. Using the Modified Fournier Index's rainfall and runoff factor equations, the Modified Fournier Index made an error.

Pioneer biocrust communities prevent soil erosion in temperate forests after disturbances

Soil erosion continues to be one of the most significant environmental challenges of our time, and it is exacerbated by global climate change. To date, very little attention has been paid to the growth of nonvascular plants, such as bryophytes, in depressed areas of temperate forests and their effects on soil erosion. This study explored pioneer vegetation in skid trails in a central European temperate forest's natural succession and their effect on soil erosion. In general, skid trails on clayey substrates revealed a significant increase in bryophyte coverage and species richness. Although bryophytes were later overthrown by vascular plants, they continued to coexist until their expansion was limited as a result of leaf litter fall. The two most popular and persistent pioneer bryophyte species, Oxyrrhynchium hians, were the most popular and persistent pioneer bryophyte species, with Dicranella schreberiana and Pohlia lutescens being local and quickly debased in the summer, while Dicranella schreberiana and Pohlia lutescens were te species, while Dicranella horna x thronsci settlers bryophyte species, Brachyrhyrhyn bry dyna chen rhyrhyrhyte species, ochli chae species bruch lutescium lutescens lutescenscenscenscium henscyrhyrhy lutescenscenscenscyrhylia tule henscium ché huste henscenscium hexo In the wheel tracks, sediment discharge was 22 times higher on disturbed bare soil than in undisturbed forest soil, and it had the most significant sediment removal in the wheel tracks. Soil erosion progressively with surface vegetation repair, becoming particularly vulnerable in summer with rising pioneer biocrusts, but it rose in winter as vascular vegetation became dominant. This leads to the conclusion that bryophyte-dominated biocrusts in forests has been underestimated so far, and they can contribute more to soil preservation at certain times of succession than vascular plants.

Remote Sensing Quantitative Research on Soil Erosion in the Upper Reaches of the Minjiang River

The Minjiang River's upper reaches form a vital ecological barrier to the Yangtze River and Chengdu Plain's upper reaches. They are also Chengdu Plain's water supplies. This report mainly uses the USLE model to quantitatively assess ecosystem services on soil erosion and soil conservation in a geographic region. The results reveal that 1 of the rain erosivity factor R is between 85. 02 and 588. 69 MJ/hu2022h/u2022a, with urban pattern similar to that of annual average precipitation. Soil erodibility factor K is between 0. 12 and 0. 30 hm2 mm, with zonal distribution in the desert and corresponding to soil types. The land use and coverage determines the soil use and coverage, with Pranging from 0 to 1. With empirical models, it is still difficult to determine the physical process of soil erosion.

Soil Erosion in the United States. Present and Future (2020-2050)

Soil erosion is a significant threat to the climate and long-term land management around the world. Here, we estimate/predict soil erosion rates by water erosion using three hypothetical Shared Socioeconomic Pathway and Representative Concentration Pathway scenarios throughout the contiguous United States. With current agricultural conservation techniques, the baseline model estimates soil erosion rates of 2. 32 Mg ha 1 yr 1 yr 1 yr 1.

A review of soil erosion modeling by R/USLE in Morocco: Achievements and limits

Soil erosion is a leading cause of land degradation. The Universal Soil Loss Equation and its updated version, the Revised Universal Soil Loss Equation, one of the empirical tools used globally for soil erosion assessment is one of the universal Soil Loss Equation and its updated version, the Universal Soil Loss Equation. This research paper's aim was to determine the potential use of R/USLE models in Morocco. The 56 published papers related to R/USLE models conducted in Morocco during the first use until 2020 were collected and reviewed in order to evaluate the statues of the R/USLE models' applications.

Assessment of soil erosion using two spatial approaches: RUSLE and SWAT Model

We attempted to investigate the erosion in the Ouergha watershed in this paper by using two spatial methods. The Ouergha watershed has a total area of 7300 km/b2, representing approximately 18. 2% of the Sebou basin, of which it is the main tributary. In order to create the erosion map using the SWAT method, it was critical to establish a large spatial database describing basin proprieties, as well as current hydrographic data. Soil erosion in the Ouergha watershed is estimated at 27 ton/year/year and 25 ton/ha/year respectively, according to the Oustergha watershed. Average sediment yield for the Al Wahda dam of 10. 4 million tons was estimated on average.

Multifractal Features of Particle-Size Distribution and Their Relationships With Soil Erosion Resistance Under Different Vegetation Types in Debris Flow Basin

To determine the effects of sediment control by vegetation restoration, understanding the effects of sediment control by vegetation restoration is critical. Using the laser diffraction technique, a total of 60 soil samples were collected and analyzed for soil particle size distribution. The number of silt particles in shrub and forest is significantly higher than that in bare land, meadow, though the total volume fraction of sand particles in bare land and meadow exceeds that in shrub and forest. In each vegetation type, the soil particle size distribution along soil layers has no significant difference. The volumetric fractal dimension is significantly higher in wood and shrub than in bare land and grassland, but there is no significant difference between forest and shrub. In dry-hot valley regions, this research provides further insight into soil structure improvement and the effects of erosion control by vegetation restoration in drought-hot valley areas.

Application of geospatial technology coupled with fuzzy logic operations in mapping soil-erosion critical zones: the case of guder sub-basin, upper blue nile basin, ethiopia

In Ethiopia's Guder sub-basin, the research sought to identify soil-erosion critical areas. As inputs, a digital elevation model, precipitation data covering 30 years, soil type, and land use were used to map soil erosion sensitive areas. On the ArcGIS 10. 5 platform, Fuzzy logic techniques based on Geographic Information Systems were integrated and analyzed. The study's findings may help decision makers and policymakers plan and implement effective watershed management plans in highly disadvantaged areas to soil erosion. When combined with GIS, Fuzzy logic approaches have been found to be a simple tool for determining erosion points in major areas. The majority of the study areas were prone to soil erosion as a result of agricultural activities, necessitating integrated soil and water conservation methods, according to the final soil erosion map.
