Soil Erosion, Different Approaches and Techniques Applied to Gullies and Trail Erosion

Abstract

Esse artigo aborda erosão dos solos, em áreas rurais e urbanas, bem como geoturismo e geodiversidade, especialmente erosão em trilhas. Aborda diversos aspectos da erosão dos solos, levando em conta conceitos, teorias e metodologias envolvidas. O artigo apresenta diferentes técnicas para monitorar erosão, desde as mais tradicionais, como estacas colocadas no solo, até as mais modernas, como VANTs e Laser Scanner Terrestre. Os resultados apontam para a necessidade de continuar as pesquisas em erosão dos solos, porque, uma vez que esse processo geomorfológico seja melhor entendido, pode auxiliar a evitar degradação ambiental no Brasil.

Soil Erosion Modeling Using the Revised Universal Soil Loss Equation and a Geographic Information System in a Watershed in the Northeastern Brazilian Cerrado

“…The impact of rainfall is one of the main factors in aggregate breakdown as well as the shear stress of water flow. This process generates soil erosion from the transport of sediment [10,11,21]. Erodibility is related to the susceptibility of soils to erosion by rainwater and runoff, is a parameter of great importance for predicting soil loss, and is associated with soil physical and chemical properties [21][22][23].…”

“…This process generates soil erosion from the transport of sediment [10,11,21]. Erodibility is related to the susceptibility of soils to erosion by rainwater and runoff, is a parameter of great importance for predicting soil loss, and is associated with soil physical and chemical properties [21][22][23]. The topographic factor is an essential parameter in determining the influence of slope (factor S) and slope length (L) in order to quantify the erosion generated by the influence of the water velocity from surface runoff [24,25].…”

Erosion Pins: Installation, Readings, and Calculations of Soil Losses under the Effect of Hydrogel

“…Pins are widely used to measure the retreat of gully edges and riverbanks. On slopes, pins have enabled measurements of sheet erosion and estimates of soil losses (HART et al, 2017;JUGIE et al, 2018;KEARNEY et al, 2018;MYERS et al, 2019;GUERRA et al, 2020;GHOLAMI et al, 2021). collection, low maintenance requirements which reduces operational costs, the possibility of data collection at flexible intervals, whether weekly, monthly, or annually, ease of detection in areas where erosion is occurring, and particularly the low technical level required for data collection Despite the advantages of this methodology, there is a scarcity of studies that demonstrate the systematization of data from erosion pin readings, as well as the calculations of soil losses under the application of hydrogels from the field readings.…”
