About Drainage Design Management System for Windows, Version 6.0.5

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. Small bugs found in version 5.6.0 have been resolved in version 6.0.5.

New Features of DDMSW 6.0.5

The DDMSW version 6.0.5 has been enhanced with the following new features:

General

  • Projects color classification per the following categories
    • HEC-1 Model
    • Rational Method
    • River Mechanics
  • Select of agency default values
  • Add location of GIS files to project paths
  • Rainfall calculation from Lat/Long and from state plain coordinates
  • Inclusion of DDMSW version number in the report header
  • Backup of all projects at one time
  • Combine results reports into one PDF document
  • Improved directory browsing

Hydrology

  • New USGS envelope curves based on 2018 Hydrology Manual
  • Import of major basin from another project
  • New form for use of DSS file for HEC-1 modeling
  • Modified Rational Method volume hydrograph to make it equal to 2-hour 100-year volume modifying rising limb.
  • Included maximum flow, volume and rating curve for diversions

River Mechanics

  • Import of cross sections from CSV file format
  • Update of general scour with Neill and HEC-18 with pressure flow
  • Update of pier scour influence zone
  • Update of launchable riprap for CVI
  • Updated reference to the River Mechanics manual of April 30th, 2021
  • Use of main channel velocity, instead of cross section velocity, to calculate riprap sizing
  • Import long term scour depth from the following sediment transport models:
    • Fluvial-12 
    • HEC-6
    • HEC-6T
    • HEC-RAS
  • Comparison of minimum/maximum thalweg elevations between two of the following models:
    • Fluvial-12 
    • Fluvial-12 (2020)
    • HEC-6
    • HEC-6T
    • HEC-RAS
