Data for “Impact of multiscale heterogeneous sediments and boundary conditions on dispersivity spatial variations”

SOWCOM is applicable to one-, two-, or threedimensional geologic domains with physical and chemical heterogeneity and can be applied to a wide range of subsurface conditions. The temperature (T) and pressure (P) ranges are controlled by the applicable range of the chemical thermodynamic database. Thermodynamic databases from external sources are included with the distribution files. Typically, these thermodynamic databases are available for temperatures between 0 and 300°C, at 1 bar below 100°C, and water saturation pressure above 100°C. The temperature and pressure range of thermodynamic data can be extended by changing the thermodynamic database without code modifications. It is the user’s responsibility to ensure that the thermodynamic data used with this software is appropriate for the temperature and pressure range of the simulated systems. Water saturation can vary from completely dry to fully water-saturated. The model can deal with ionic strengths from dilute to moderately saline water (up to ionic strengths in the 2–4 molal range, for an NaCl-dominant solution, depending on the system being modeled.
