| Resumo | Advancements in environmental geophysics field, allied with modern computational and statistical techniques, have significantly contributed to understanding environmental phenomena occurring on Earths surface and subsurface. Remotely sensed, geophysical and field data associated with soils lithology, mineralogy, physics, and chemistry, when combined enable to assessment and modeling of basins water resources distribution. However, potential integration of geophysical maps in favorability and hydrological dynamics analysis using Digital Soil Mapping (DSM) requires further investigations. This study explores geophysical aerial survey data integration with remote sensing and landscape analysis data for DSM applications, focusing on characterizing geospatial soils physical-hydric attributes behavior in GuapiMacacu watershed, Rio de Janeiro. We analyzed 122 in-situ hydropedological data points, representing saturated hydraulic conductivity (ksat) values at two depth intervals (0-20cm and 20-40cm), and crossed it with information extracted from Digital Terrain Modeling (DTM), aerogeophysics, and spectral indices. Geomorphometric variables were derived from Brazilian Institute of Geography and Statistics planialmetric survey at a 1:25000 scale. Aerogeophysical data from Brazil Geological Survey, comprising bidirectional radiometric (magnetometric) and minimum curvature (gamma-ray) grids for uranium, thorium, and Potassium elements count, were utilized. Spectral indices were calculated from MSI/Sentinel-2 images. The complete dataset encompassed 36 landscape variables, 13 indices, and 4 aerogeophysical grids. Statistical techniques were employed for data selection, dimensionality reduction, and modeling. The results indicated that geophysical variables were integral to the hydropedological modeling of both the surface (0-20cm) and subsurface (20-40cm) soil layers, achieving high R2 values (> 0.86) and low prediction errors (RMSE < 0.005, MAE < 0.003), thus effectively representing regions soils water infiltration capacity. Consequently, these models reduced more efficiently the dataset dimensionality and represented more faithfully soils water infiltration capacity, confirmed through qualitative analysis of geological maps for the area. The aerogeophysics products integration proved to be an interesting artifice for hydropedological mapping enhancing, emphasizing their potential for characterizing, and representing surface and subsurface soil water dynamics. | |||
