Summary Also known as Model type Single Model part of larger framework Note on status model Date note status model biogeochemistry, water quality, Technical specs Supported platforms Unix, Linux Other platform Programming language Fortran77 Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 1991 Does model development still take place? Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code, As executable"As executable" is not in the list (As code, As teaching tool) of allowed values for the "Model availability" property. Source code availability (Or provide future intension) Through web repository Source web address http://water.usgs.gov/software/OTEQ/ Source csdms web address Program license type Other Program license type other http://water.usgs.gov/software/help/notice/ Memory requirements Typical run time In/Output Describe input parameters see user documentation Input format ASCII Other input format Describe output parameters Solute concentrations as a function of space and time Output format ASCII Other output format Pre-processing software needed? Yes Describe pre-processing software All I/O is done with flat ASCII files; The 'MINTEQ Input file' is created using the Proteq utility; remaining input files may be created using a text editor Post-processing software needed? Yes Describe post-processing software All I/O is done with flat ASCII files; Output files are first processed by a utility (posteq) -- resultant files can then be plotted with the user's own software. Visualization software needed? No If above answer is yes Other visualization software Process Describe processes represented by the model Physical transport: Advection, Dispersion, Inflow, Transient Storage, and Settling. Chemistry: Precipitation/Dissolution, Sorption/Desorption, Oxidation/Reduction, aqueous complexation, and acid-base reactions Describe key physical parameters and equations Partial differential equations describing mass transport (Advection-Dispersion-Reaction equations) and algebraic equations describing chemical equilibria are coupled using the Sequential Iteration Approach Describe length scale and resolution constraints Describe time scale and resolution constraints Describe any numerical limitations and issues see numerical aspects described in Section 4 of the documentation Testing Describe available calibration data sets see user documentation; also see applications at http://water.usgs.gov/software/OTEQ/apps/ Upload calibration data sets if available: Describe available test data sets see user documentation; also see applications at http://water.usgs.gov/software/OTEQ/apps/ Upload test data sets if available: Describe ideal data for testing Other Do you have current or future plans for collaborating with other researchers?
