Importing HEC-1 Stand-Alone Input File

About the Tutorial

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 are 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.

See Tutorial #23 (only for DDMSW 5.6.0) on “Import HEC-1 Model and Update Losses” for procedural guide on updating model loss parameters when supporting project datasets are available.
