At times, instead of assigning values at the upstream and downstream ends of the arc, it is useful to assign a property using a surface. This can be done in GMS using a TIN.
When the arc is discretized onto the model grid, the cells that intersect the arc are found. Then the boundary condition property is interpolated from the TIN to the cell centers.
Beginning with version 9.1, it is also possible to assign TINs with transient datasets. This gives the option to have a surface that changes with time assigned to a boundary condition property. The times associated with the TIN dataset can be in date/time format or relative time format.
There is a user preference for treating the transient data on the TIN as a step function or as a continuous curve. This option is selected when performing the Map→MODFLOW operation under the Transient TIN datasets section.
