Rainfall erosivity estimation over the Tibetan plateau based on high spatial-temporal resolution rainfall records

Yueli Chen et al.

Summary: This study used weather station data to estimate rainfall erosivity in the Tibetan Plateau and identified spatial-temporal patterns of rainfall erosivity. The results showed that the annual erosive rainfall accounted for 53% of the total rainfall, with an average of 14 erosive events per weather station per year. The study also found that erosive events in the wet season were more likely to extend past midnight. Additionally, the study revealed significant spatial variability in rainfall erosivity, with the highest values in forest zones.

Estimating the Impact of Land Cover Change on Soil Erosion Using Remote Sensing and GIS Data by USLE Model and Scenario Design

Anmin Fu et al.

Summary: The study evaluated the impact of returning farmland to the forest on soil erosion in Inner Mongolia, China through scenario construction and comparison with actual data, revealing that land use/cover change and rainfall-runoff erosivity change have significant effects on soil erosion.

High-resolution soil erodibility map of Brazil

Raquel de Faria Godoi et al.

Summary: Large-scale soil erosion modeling plays a crucial role in soil and water conservation planning. The lack of spatial data on soil characteristics has been a major obstacle in Brazil for computing the soil erodibility (K-factor). In this study, a high-resolution spatially explicit soil erodibility map was computed using USLE nomograph and EPIC equations, with USLE nomograph providing more precise estimation of the K-factor in Brazil compared to EPIC.

Balsas river basin: physical diagnosis and qualitative presentation of erosion-susceptible areas

Ana Paula de Melo e Silva Vaz et al.

Summary: This study aimed to make a physical diagnosis and indicate areas susceptible to erosion in the Balsas river basin in Brazil. Using information from various databases, geoprocessing routines were employed to map the basin and sub-basins, calculate morphometric indices, and reclassify areas susceptible to erosion. The findings indicate the need for management and planning actions to prevent negative impacts of erosive processes in the region.
