LAS CRUCES DATABASE. Las Cruces Trench Site Database, Vadose Model

The LAS CRUCES TRENCH SITE DATABASE includes raw and processed experimental data obtained from the vadose zone model validation experiments performed on the New Mexico State Ranch northeast of Las Cruces, New Mexico. Included are data characterizing the unsaturated hydraulic properties for the experimental site and dynamic data, such as water contents, tensions, and solute concentrations, obtained during two infiltration redistribution experiments. At the site, a 26.4m long, 4.5m wide, and 5 mile deep trench was constructed in undisturbed soil. During construction a total of 594 disturbed soil samples and 594 associated soil cores were taken from 9 distinct soil layers identified on the north wall. Samples were also taken from three vertical transects on this wall. Data included in the database are sample locations, a description of the 9 soil layers, bore hole saturated hydraulic conductivities and outflow data, laboratory saturated hydraulic conductivities, soil water retention data, particle size distribution data, bulk density data, parameters used to fit the van Genuchten equation to the water retention data, and estimated van Genuchten parameters for each layer and the entire site. Data obtained from two experiments designed to provide data for testing deterministic and stochastic models of vadose zone flow and transport are also included.
