Abstract

The land use is one of the main controlling factors on hillslope processes. The land rotation system has influences on the hillslope hydrological processes; also this information is scarce in the center-south Paraná region. Hence, this study has as its aim to verify the land rotation system effects on hydrological processes related to steep slope covered by shallow soil. Previous mapping of the study area was carried out, afterward a range of field measurement was done (e.g soil physical-hydric characteristics; runoff, soil humidity and interception). The theoretical base for interpretation of the hillslope processes followed the DALRYMPLE et al. (1968) proposal (Hypothetical nine-unity lansurface model). It was verified that the land rotation system dynamics as well the hillslope geomorphopedological complexity induces subsurface hydrological processes. These processes are fundamental to hillslope instability triggering, also to developing and expanding the first-order canal.
