RDII Files

The RDII interface file is a text file that contains a time series of rainfall-dependent infiltration/inflow flows for a specified set of drainage system nodes. This file can be generated from a previous GeoSWMM run when Unit Hydrographs and nodal RDII inflow data have been defined for the project, or it can be created outside of GeoSWMM using some other source of RDII data (e.g., through measurements or output from a different computer program). The format of the file is the same as that of the routing interface file discussed below, where Flow is the only variable contained in the file.
