ADH stands for ADaptive Hydrology/Hydraulics and is a model being developed by the US Army Corps of Engineers (USACE). An interface to ADH is being added to GMS. ADH is currently only available to individuals in USACE. | ADH stands for ADaptive Hydrology/Hydraulics and is a numerical model being developed by the US Army Corps of Engineers (USACE).

ADH uses node, face and edge sets to define locations on the [[GMS:3D Mesh Module|3D mesh]] where [[GMS:ADH#Boundary | ADH uses node, face and edge sets to define locations on the [[GMS:3D Mesh Module|3D mesh]] where [[GMS:ADH#Boundary conditions|boundary conditions]] are located. These sets are created and deleted separately from the boundary conditions, which makes for great flexibility. GMS associates names with the sets for convenience and automatically numbers the sets when saving the ADH input files. | ||

Existing sets can be viewed and edited using the ''ADH|View Sets'' menu command. This brings up the View Sets dialog which lists the existing sets. Selecting sets in the list will cause the corresponding items on the 3D mesh to be selected and highlighted. The name of the set can be edited, but adding or removing items from the set is not allowed. If this type of editing is desired, you must delete the set and recreate it with the correct items. | Existing sets can be viewed and edited using the ''ADH|View Sets'' menu command.

The ADH Analysis Options dialog is used to specify general and global model variables. For more information on each variable refer to the [https://docs.google.com/a/aquaveo.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AqifJlc0bOSpdFFmYjZUbVctRG50eGFMazRNdVdib2c&output=html ADH file format cards supported in GMS]. | The ADH Analysis Options dialog is used to specify general and global model variables.

The ADH Output Control dialog shows options for ADH output. The times at which ADH will generate output are listed in the spreadsheet. Times can be added or removed or pasted from another application. Times can also be added using the options under "Add times". | The ADH Output Control dialog shows options for ADH output.

"Constituents" are analogous to [[GMS:MT3DMS|MT3DMS]] "species" and represent mass that moves through water when modeling transport. Constituents will be ignored by ADH (but still saved to the BC file) unless the "Solve constituent transport equation (OP TRN)" option is turned on in the [[GMS:ADH#Analysis | "Constituents" are analogous to [[GMS:MT3DMS|MT3DMS]] "species" and represent mass that moves through water when modeling transport.

GMS allows constituents to be named for convenience but ADH ignores this name. | ||

The number of constituent material properties, therefore, equals M X C where M is the number of materials and C is the number of constituents. Changing either M or C will change the number of rows in the ADH Constituent Material Properties dialog. | The number of constituent material properties, therefore, equals M X C where M is the number of materials and C is the number of constituents.

==Boundary | ==Boundary conditions== | ||
ADH boundary conditions can be created, deleted and edited via the ADH Boundary Conditions dialog. Boundary conditions are associated with a [[GMS:ADH#Node, face and edge sets|node, face or edge set]] to position them on the [[GMS:3D Mesh Module|3D mesh]]. Different boundary conditions apply to different "physics components" (also called "operations") as defined in the [[GMS:ADH#Analysis | ADH boundary conditions can be created, deleted and edited via the ADH Boundary Conditions dialog.

Different boundary conditions apply to different "physics components" (also called "operations") as defined in the [[GMS:ADH#Analysis options|ADH Analysis Options]] dialog. GMS, however, allows you to define any boundary conditions regardless of the current settings in the Analysis Options dialog so that you can switch the analysis options and quickly try out different scenarios. | ||
