Resumo: | The northwest region of the state of Paraná over the last 50 years has suffered several impacts and consequences of linear erosives, ravines and gullies mainly. The occurrence of these processes is mainly associated with two factors: the occupation history of the region, as well as local soil characteristics, mainly the soil texture and a distribution of soils along the slopes. The methodology adopted for the mapping of susceptibility to erosion follows a line of thought developed by Crepani et al. (2001). This proposal defines that the vulnerability of an area is defined by the sum of the vulnerabilities of the components of the physical environment. For the accomplishment of the methodology were selected, to represent the geomorphology, the topographic attributes: slope, curvature plane and profile; for pedology, soil typologies were selected. The results were discretized in 5 classes, from environments less susceptible to the most susceptible. The areas of susceptibility to erosion High and Very high, summed represent 24% of the municipality, being that in these portions it concentrates 26% of the area of the erosions, once in these areas the type of soil together with the topographic characteristics make it more propitious to the occurrence of linear erosive processes.The moderate susceptibility to erosion class represent about 40% of the municipality and 54% of the area of erosive features is concentrated in this unit. |

La ocurrencia de estos procesos está asociada a dos factores: el modo de ocupación de la región y las características pedológicas locales, principalmente la textura de los suelos y su distribución en las vertientes. El método adoptado para el mapeo de susceptibilidad es una adaptación del propuesto por Crepani et al. (2001). Este autor especifica que la susceptibilidad de un área está definida por la suma de las vulnerabilidades de los componentes del medio físico. Para realizar este trabajo fueron seleccionados los atributos topográficos declividad y perfil de curvatura; en la pedología, las tipologías de suelo. Los resultados fueron representados en 5 clases: muy baja, baja, media, alta y muy alta susceptibilidad. Las áreas de susceptibilidad a erosión alta y muy alta, representan el 24% del municipio, sumado a ello en esas porciones se concentran el 26% de las erosiones, por lo tanto el tipo de suelo en conjunto con las características topográficas hacen de esas áreas las más propicias naturalmente a la ocurrencia de procesos erosivos. La clase de moderada susceptibilidad a erosión representa cerca del 40% del municipio y el 54% de los rasgos erosivos se concentran en esa unidad.A região noroeste do estado do Paraná ao longo dos últimos 50 anos vem sofrendo diversos impactos decorrentes de processos erosivos lineares, ravinas e voçorocas principalmente.
