Dam Breach modeling in HydroCAD-10
Dam Breach modeling in HydroCAD-10
(OP)
HydroCAD-10 includes a dam breach capability which makes the detail in this previous thread obsolete: thread789-280898: Dam Break in HydroCAD
The new dam breach outlet allows for a progressive breach triggered at any desired time or water surface elevation. The breach itself if modeled as a rectangular or trapezoidal weir whose height increases linearly over the specified time. When using a tailwater-sensitive routing procedure, the breach can also respond to tailwater conditions created by a downstream reach or pond. For complete details see www.hydrocad.net/dambreach.htm
