About Drainage Design Management System for Window 4.8.0
The Drainage Design Management System for Windows (DDMSW) program is a pre-processing tool for HEC-1 rainfall-runoff model. This new release of DDMSW provides new features and capabilities that enhance the development of HEC-1 model and use of Rational Method as well as in the post-processing of model results.
In addition to the improvements on the hydrology module, significant refinements have also been implemented on the river mechanics module including:
- Lateral Erosion
- Launch-Able Riprap
- Low-Flow Incisement Methodology
- Riprap Sizing
- Sediment Yield Analysis
