abstract = "The present study aimed to evaluate the relationship between the
physical properties of the soil and relief in areas that are
susceptible to landslides in the sub-basin of the C{\'o}rrego do
Yung, a creek in the urban district Tr{\^e}s Moinhos of Juiz de
Fora, Minas Gerais. Depth measurements of the solum were made at
the soil sampling points, and the subsurface material was
collected and analyzed for the two factors of particle size and
type of horizon. In the laboratory, we determined the hydraulic
conductivity, bulk and particle density, and total porosity,
macroporosity and microporosity. The values of the physical
properties throughout the sub-basin were predicted and mapped.
Thematic maps were generated and showed a relation to each other:
the clay was related to a higher hydraulic conductivity, higher
porosity and lower soil density. In the steeper areas, the greater
silt contents were mapped in the deeper layers and indicated the
thin thickness of horizon B in these areas. A close relation of
the curvature with the soil thickness was detected and was greater
in the flat areas with less slope. The geostatistical analysis
showed that the range of values for the properties of
macroporosity, microporosity and silt was the lowest in the deeper
layers, indicating low structural continuity in potentially
erodible areas.",
