Nine methodologies/adaptations were tested in 103 soil samples collected covering the main soil types in the hydrographic basin. The data were submitted to a validation proposal and underwent descriptive and correlation statistical analyses. A spatial dependence analysis and mapping by kriging was also carried out. The methodologies that best represented the erodibility estimates at PRHB were those by Sharpley and Williams (Latossolos Vermelho-Escuros Oxisols and Planossolos Alfisols), Wischmeier and Smith (Latossolos Roxos Oxisols), and Renard (Podzólicos Vermelho-Escuros and Podzólicos Vermelho-Amarelos Ultisols). The final map indicated erodibility medium (46.4% of PRHB), low (45.1%), very low (0.5%) and very high (7.9%). The findings indicated that the use of a single indirect methodology may underestimate or overestimate the soil erodibility. 2021 artículo científico 1984-2201 https://www.redalyc.org/articulo.oa?id=273667617013 https://www.redalyc.org/journal/2736/273667617013/ https://www.redalyc.org/journal/2736/273667617013/html/ https://www.redalyc.org/journal/2736/273667617013/273667617013.epub https://www.redalyc.org/journal/2736/273667617013/movil en http://www.redalyc.org/revista.oa?id=2736 Mercator - Revista de Geografia da UFC application/pdf Universidade Federal do Ceará Mercator - Revista de Geografia da UFC (Brasil) Num.2 Vol.20 |
