From classificationprocedures we obtained six NDVI patterns (P1 to P6) differing in their mean values; standard deviation; and seasonality.The NDVI patterns are evidence of different situations in terms of elevation; flood dynamics; and vegetation physiognomies: P1 represents water bodies; P2 to P4 cover frequently flooded lowlands colonized by marshy vegetation; and P5 and P6 are placed on middle and high elevations that are less flooded and also are covered by tall vegetation (grassland and forest).

The spatial arrangement of the two belts is similar to limits followed by the morphodynamic areas of the Paraná fluvial system. More than 60% of the surface covered by P2 and P5 corresponds to low morphodynamic areas while nearly 70% of P6 matches with high morphodynamic areas.

From classificationprocedures we obtained six NDVI patterns (P1 to P6) differing in their mean values; standard deviation; and seasonality.The NDVI patterns are evidence of different situations in terms of elevation; flood dynamics; and vegetation physiognomies: P1 represents water bodies; P2 to P4 cover frequently flooded lowlands colonized by marshy vegetation; and P5 and P6 are placed on middle and high elevations that are less flooded and also are covered by tall vegetation (grassland and forest).
