What is Rosetta capable of predicting?
The present version of Rosetta is capable of predicting van Genuchten (1980) water retention and unsaturated hydraulic conductivity parameters, as well as of providing estimates of the saturated hydraulic conductivity, Ks. The van Genuchten water retention function is given by:
What is Rosetta based on?
Rosetta is based on ACCESS-97 database tables which allow efficient handling and lookup of small and large volumes of data. Data can be either manually entered or read from ASCII files. The maximum amount of samples (records) that Rosetta can handle is limited by the available hard disk space. Estimated hydraulic properties can be exported in ASCII files and used in other programs. ACCESS-97 is not required to run Rosetta; however, ACCESS-97 can be used to manage Rosetta's predictions in a larger project, provided that the tables created by Rosetta are not altered.
What is the help system in Rosetta?
Rosetta contains extensive help files that explain how to use the various menu options and screens. The help system also contains two tutorials that illustrate most functions in Rosetta. Furthermore, the help system contains extensive information about the background of Rosetta (data used for calibration, calibration results, neural networks and the bootstrap method).
