The Integrated Precipitation and Hydrology Experiment - Hydrologic applications for the Southeast US (IPHEx-H4SE) Part IV: Soil Hydraulic Parameters


Soil hydraulic parameters (i.e. saturated hydraulic conductivity, porosity, field capacity and wilting point) at high spatial resolution (1km×1km) were prepared for the IPHEx-H4SE project (Integrated Precipitation and Hydrology Experiment – Hydrologic Applications for the Southeast US). The data sets were extracted from the State Soil Geographic (STATSGO) database ( for the Southeast US in the IPHEx-H4SE domain at 11 standard soil layers defined in STATSGO, i.e. 0~5cm, 5~10cm, 10~20cm, 20~30cm, 30~40cm, 40~60cm, 60~80cm, 80~100cm, 100~150cm, 150~200cm and 200~250cm. The original data were extracted, projected to UTM 17N and resampled to 1km resolution. Missing data are represented by -9999. The soil data provide most common soil properties required by hydrological modeling. UTM 17N (WGS84), resolution 1Km, boundary info: Top 4135816.67952; Left 57548.6334476; Right 773548.633448; Bottom 3525816.67952 These data were originally made available at and were migrated to the Duke Digital Repository on 11/20/2017.
