RT3D is a multi-species reactive transport model developed by the Battelle Pacific Northwest National Laboratory. RT3D is a modified version of MT3DMS that utilizes alternate Chemical Reaction packages. Numerous pre-defined reactions are available and an option is provided for creating user-defined reactions. RT3D is well-suited for simulating natural attenuation and bioremediation. | RT3D is a multi-species reactive transport model developed by the Battelle Pacific Northwest National Laboratory.

Since RT3D is a modified version of MT3DMS, most of the input to RT3D is identical to the input required for MT3DMS. Thus, the RT3D interface is contained within the MT3D menu in the 3D Grid module.

Thus, the RT3D interface is contained within the ''MT3D'' menu in the 3D Grid module. In the [[GMS:Basic Transport Package Dialog|''Basic Transport Package'']] dialog, an option is provided for selecting the current model as either MT3DMS, RT3D, or SEAM3D. A number of options in the interface then change based on which model is selected. | ||
Since much of the RT3D interface is identical to the [[GMS:MT3DMS|MT3DMS Interface]], only the portions of the interface which are unique to RT3D are described in this help file. | Since much of the RT3D interface is identical to the [[GMS:MT3DMS|MT3DMS Interface]], only the portions of the interface which are unique to RT3D are described in this help file. | ||

The first step in defining an RT3D simulation is to define the data required by the Basic Transport (BTN) package. The options in the [[GMS:Basic Transport Package Dialog|Basic Transport Package dialog]] unique to RT3D are as follows: | The first step in defining an RT3D simulation is to define the data required by the Basic Transport (BTN) package.

The Packages button brings up the Packages dialog. If the RT3D model is the current model and the Chemical Reaction package is selected, one of the RT3D reactions must be selected from the pull-down list. The first nine reactions are pre-defined reaction types. If one of these reactions is selected, the names of the species and the names of the reaction parameters are automatically determined by GMS. The last reaction is a user-defined reaction. If this option is selected, a list of species and list of reaction parameters must be specified by the user. | The Packages button brings up the ''Packages'' dialog.

For most of the reaction package options, once the reaction package is selected, the list of species used by the package is automatically initialized by GMS. However, if the user-defined reaction package is selected, the Define Species button is undimmed in the Basic Transport Package dialog and a list of species must be manually defined before any concentrations are assigned to sources/sinks. | For most of the reaction package options, once the reaction package is selected, the list of species used by the package is automatically initialized by GMS.
