SWMM 4 DWF File

Introduction

A version of the SWMM 4 DWF input data is read by SWMM 5 if the keyword

#K1_K3_FILE_DATE

is found in the Titles/Notes Category.  The file can be copied from the SWMM 4 input data file and placed in a separate file.  

The name and location of the DWF data file is found by using the Data command:

Data-->Options-->Interface Files

and then selecting the ADD button and picking INFLOWS  from the pull down menu.  The program will use the iface.c routines in the SWMM 5 C code but read the DWF file using the SWMM 4 data file format.

The SWMM 5 output text file will list the DWF File Summary as a verification of the DWF read during the simulation.  The next Table shows a snippet of one output file.
