Abstract
This report contains general documentation and serves as a user manual of the UNSODA program. UNSODA is a database of unsaturated soil hydraulic properties (water retention, hydraulic conductivity, and soil water diffusivity), basic soil properties (particle-size distribution, bulk density, organic matter content, etc.), and additional information regarding the soil and the experimental procedures. The program can be used to (1) store and edit data, (2) search for data sets based on user-defined query specifications, (3) write the contents of selected data sets to an output device, and (4) describe the unsaturated hydraulic data with closed-form analytical expressions. This report gives a broad overview of major features operations of UNSODA and documents the main tables. The data collection process is outlined and each input variable is discussed. UNSODA allows the analytic description of unsaturated hydraulic properties by means of parametric models; six default models are for this purpose included in the program. The program module for optimization of hydraulic model parameters is written in FORTRAN. Users can easily add additional hydraulic models. Three examples are included to show the reader step-by-step how UNSODA can be used to (1) enter and edit data, (2) search and report data, and (3) model hydraulic data.
