Quantification and categorization of soil loss due to water erosion in the basin of arroyo Santa María, Corrientes, Argentina
This study focused on the plain basin of the Santa María stream, located in the north-central region of Corrientes Province, Argentina. The primary objective was to assess and categorize soil degradation through the quantitative estimation of potential (Ap) and actual (A) water erosion, utilizing a...

Kurtz, Ditmar B. Basin EUPS erosion GIS Cuenca EUPS erosión SIG This study focused on the plain basin of the Santa María stream, located in the north-central region of Corrientes Province, Argentina. The primary objective was to assess and categorize soil degradation through the quantitative estimation of potential (Ap) and actual (A) water erosion, utilizing a Geographic Information System (GIS) framework. Twenty-one sites were selected based on soil types, land use, and management practices. A correlation analysis was performed among soil erodibility factors (K), slope length (L), and slope steepness (S) with Ap. The results indicated that K values accounted for 73% of the variation in Ap, while slope length and steepness explained 54%. The analysis revealed that 65.96% of the basin’s area (42,161.9 ha) was classified as having moderately low erosion potential, with estimated soil losses ranging from 20 to 50 Mg·ha⁻¹·yr⁻¹. Additionally, the assessment of actual soil loss due to water erosion showed that 79% of the Santa María basin experienced very low soil losses, measuring less than 10 Mg·ha⁻¹·yr⁻¹. Se analizó la cuenca de llanura del arroyo Santa María (centro-norte de la provincia de Corrientes, Argentina). El objetivo fue evaluar y categorizar la degradación de suelos mediante la estimación cuantitativa de erosión hídrica potencial (Ap) y actual (A), utilizando un entorno SIG. Se seleccionaron sitios mediante tipos, usos y manejos de suelos, resultando en 21 sitios de evaluación. Se realizó la correlación entre los factores de erodabilidad del suelo (K), el efecto de la longitud (L) y la pendiente (S) y la Ap. Los cálculos de Ap para cada sitio en la cuenca indicaron que el 73% de la variación de la Ap está explicada por los valores de K, mientras que los valores del grado y longitud de pendiente explican el 54%. Al calcular Ap, el 65,96% de la superficie de la cuenca (42161,9 ha) se clasificaron como moderadamente baja, significando pérdidas de suelo entre 20-50 Mg.ha-1.año-1. El cálculo de la pérdida de suelo por erosión hídrica actual para cada sitio evaluado permitió evidenciar que el 79% de la cuenca del arroyo Santa María presenta pérdidas de suelos Muy Bajas (inferiores a 10 Mg.ha-1.año-1).
