Predicted saturated hydraulic conductivity for 6 soil layers across the whole of Australia at 3 arcsecond resolution.

Full description

Geotiff files of predicted saturated hydraulic conductivity for 6 soil layers: 0-5 cm; 5-15 cm; 15-30 cm; 30-60 cm; 60-100 cm; and 100-200 cm; for the whole of Australia at 3 arc second resolution. Predictions were generated using the Soil and Landscape Grid of Australia data and the ROSETTA pedotransfer function. Results are in m/day
Lineage: Soil attributes maps from the 'Soil and Landscape Grid National Soil Attribute Maps' for 6 soil layers: 0-5cm; 5-15cm; 15-30cm; 30-60cm; 60-100cm; and 100-200cm; for the whole of Australia at 3 arc second resolution for each of: Clay (1), Sand (2), Silt (3), Bulk Density (BD) (4); Drained Upper Limit (DUL) (5); and15 Bar Lower Limit (L15) (5) were used as inputs. The inputs were fed into the ROSETTA (6) pedotransfer function to generate average predicted saturated hydraulic conductivity maps of the same scale and resolution for each of the 6 soil layers. Results are converted to m/day and embedded in a geotiff file.
