Importing HEC-1 Stand-Alone Input File

This tutorial outlines the approach for importing an existing HEC-1 model input file with the goal to use the reporting and graphing features of the Drainage Design Management System for Windows (DDMSW) program.

The HEC-1 model parameters in the resulting DDMSW project cannot be updated because the supporting land use, soils, sub-basin and network data sets were not included during the import. The resulting model can only be run for one storm event - the specific storm event that was defined in the original HEC-1 input file.
