Resumen
Research work is based on the preparation of a geomorphologic map and the erosive processes in the river Keller basin - PR Brazil. Scale: 1:50.000 (Reis Nakashima, (op, cit). The methodology used is centered on the landscape?s integrated analysis, based on the interrelationship of its many components, as revealed by air photographs, 1:25.000, satellite pictures, 1:100.000, topographic and thematic maps and field work. The integrated caption of the geomorphologic map of the researched was obtained (Table 1). The basin of the river Keller was subdivided into four geomorphologic units, characterized by the correlation between the units and the land patterns and morphometric, lithological, pedological and the use of land/vegetation data. A map on land patterns associated with current erosive processes (Reis Nakashima, 1999) was drawn. This approach is a good support to pedological and geomorphologic research directed towards the studies of the environment and its fragility
