About Drainage Design Management System for Windows, Version 5.6.0

The Drainage Design Management System for Windows (DDMSW) program was initially developed as a pre-processing tool for HEC-1 modeling. In recent years, functionalities of the DDMSW program have been extended to include Storm Drainage Hydraulics and River Mechanics.

New Features of DDMSW 5.6.0

DDMSW 5.6.0 offers many program enhancements including an option for users to run two different versions of DDMSW simultaneously. Other new features and capabilities are listed below:

Hydrology

  • Update Infiltration Losses for imported HEC-1 models
  • HEC-1 HC Card Cumulative Area Tool
  • NSTPS values are now integrated in the Routing report
  • Shows zero values (instead of blank) in Storage Facilities form and Report
  • Includes Volume calculation in the Hydrology Summary for Rational Method analysis
  • Includes Time to Peak values in the Hydrology Summary Results and Report for HEC-1
  • Distinct lines for Envelope curves and symbol for Diversion elements
  • Enhanced labels and mouse tips
