The stream mapping table is analogous to the grid mapping table. It defines parameter sets over links. Instead of referring to (gridded) index maps it refers to stream index maps.
The tables in the stream mapping table file currently only define the initial concentrations of constituents in the stream as well as the dispersion parameter in the stream. There are four nutrient input tables: NSM_N for initial nitrogen concentrations, NSM_P for initial phosphorous concentrations, NSM_C for initial carbon concentrations, and NSM_OTH for initial algae, carbonaceous biochemical oxygen demand, and dissolved oxygen concentrations/demands. The dispersion table is for the dispersion values along the stream. In the future there will be other tables here, such as stream roughness.
