BOSS BREACH™ is used to model the linear and non-linear failure of earthen dams and levees due to either overtopping or piping failure. It will predict the breach characteristics, such as size, shape, and time of formation, as well as will graph the computed breach outflow hydrograph.

Linear and Non-linear Failure Analysis of Earthen Dams and Levees

BOSS BREACH™ is used to model the linear and non-linear failure of earthen dams and levees. The software can account for both overtopping and piping failure processes. By defining different confidence intervals for the earthen materials used to construct the dam or levee structure, the user can quickly develop the failure mode that the structure could fail as. BOSS BREACH is used by FERC, U.S. Army Corps of Engineers, state regulatory agencies, and consultants worldwide. BOSS BREACH runs on Windows 2000, XP, and Vista. Both US and metric (SI) units are supported.

Typical complexities BOSS BREACH can address include:

  • Piping, overtopping, and progressing failure mechanisms
  • Man-made earthen dam failure analysis
  • Naturally formed (from a landslide) dam failure
  • Levee failure analysis
  • Inner and outer core materials
  • Tailwater submergence effects
  • Various spillway and turbine operating conditions

Easy to Learn and Use

BOSS BREACH is easy to learn and use. Data entry screens enable the user to easily enter or change input data. This intuitive user interface, along with its underlying database engine and expert system, allows the user to quickly define a model. Easy to use input screens, context sensitive help, and professional documentation along with complete examples assist the user at every step in creating a model.

Computational Analysis Engine

BOSS BREACH mathematically models the breaching of an earthen dam from either an overtopping or piping failure. The program predicts the dam-breach characteristics, such as size, shape, time of formation, and graphs the breach outflow hydrograph. These results can then be used as the dam-breach failure input data for BOSS DAMBRK™.

The dam being analyzed can be either man-made or have been formed naturally by a landslide, and the dam core material can differ from that of the dam’s outer material. The program will allow several other modeling complexities. Some examples are: initiation of the breach via a piping failure with subsequent progression to a free surface breach flow; forming of a downstream dam face erosion ditch, prior to the actual breach, due to overtopping water; and the sudden enlargement of the breach brought about by a structural failure due to hydrostatic pressure exceeding the resisting shear and cohesive forces of the bank material.

Advanced Graphical Output

BOSS BREACH presents its analysis results in presentation-quality graphs allowing you to quickly evaluate your work. The graphical output can be exported to AutoCAD or placed into Microsoft Word or Excel for reporting.

AutoCAD Support

The graphical output from BOSS BREACH can be exported to AutoCAD, allowing the results to be plotted on finished plan sets.

Extensive Help

Wherever you are in BOSS BREACH, extensive context-sensitive help is available to assist you through any difficulty. And with professional documentation, including illustrations and complete example problems, you can be productive immediately—even if you are a beginner. In addition, BOSS International provides technical support that you can count on—real engineers who have used the software on projects from all around the world. This guarantees that you will get your project completed on time and under budget.

Built-in Model Checker

BOSS BREACH includes a built-in Model Checker. The program’s Model Checker will analyze the input data for any modeling errors. If it encounters an error, it will explain what is wrong and suggest possible corrections. The Model Checker can be thought of as an expert modeler—pointing out any input data errors, potential modeling problems and concerns contained within the model.
