This models is useful for determining the likely fate of a chemical subject to transfer between a water column and a sediment compartment. By quantifying the transport fluxes, the relative importance of each process can be assessed. The direction of net flux can be determined by comparing the fugacities calculated assuming steady-state conditions. The clearance time for the water, sediment, or whole system can be estimated from the calculated response times. The results of changes in chemical and environmental properties may be explored by modifying the input data. Incremental changes in input properties can be used to obtain a sensitivity analysis.
Features of the Sediment model:
Provides a database of chemicals and chemical properties.
Permits temporary additions/changes of chemicals and their properties to a simulation.
Permits permanent additions, changes and deletions of chemicals and their properties to the database.
Provides a database of environments and environmental properties.
Permits temporary additions/changes of environments and their properties to a simulation.
Permits permanent additions, changes and deletions of environments and their properties to the database.
Provides context-sensitive Help.
Displays and prints the Sediment model calculations, as performed by the program.
Allows the printing of simulation tables and the summary diagram.
Allows the program results to be saved as text file viewable by standard spreadsheet software.
