DAMBRK

BOSS DAMBRK™ is the most advanced, easy-to-use one-dimensional hydrodynamic flood routing software available. The software accounts for dam and bridge failures, storage effects, floodplain overbank flow, and flood wave attenuation. BOSS DAMBRK is used for dynamic flood routing, dam safety analysis, and reservoir spillway analysis and design by FERC, U.S. Army Corps of Engineers, state regulatory agencies, and consultants worldwide.

Overview

BOSS DAMBRK™ is the most advanced, easy-to-use one-dimensional hydrodynamic flood routing software available. The software accounts for dam and bridge failures, storage effects, floodplain overbank flow, and flood wave attenuation. BOSS DAMBRK is used for dynamic flood routing, dam safety analysis, and reservoir spillway analysis and design by FERC, U.S. Army Corps of Engineers, state regulatory agencies, and consultants worldwide. BOSS DAMBRK runs on Windows personal computers, and supports virtually all graphic displays, printers, and plotters. In addition, BOSS DAMBRK network server version can operate on a local area network, allowing sharing of data files among users while maintaining individual user configurations.

Easy to Learn and Use


BOSS DAMBRK is easy to learn and use. Data entry screens enable the user to easily enter or change input dataóthere is no longer any need to struggle with cumbersome, cryptic, error-prone card input files. This intuitive user interface, along with its underlying database engine and expert system, allows the user to quickly define a model. Menus, help screens, and professional documentation aid the user at every step in defining a model. In addition, BOSS DAMBRK can import existing NWS DAMBRK card files, thereby allowing existing card file data to be used in an analysis model.

Easy-to-use data screens allow the user to quickly define a model in BOSS DAMBRK.

Built-in Data Checking

As you enter data, and just prior to the data analysis, BOSS DAMBRK automatically checks your data for errors via BOSS ADVISOR™, an integrated expert system. If the ADVISOR encounters an error in your input data, it will explain what is wrong and how you can correct it. BOSS ADVISOR can be thought of as an expert DAMBRK user, pointing out any mistakes made as you build your model.
BOSS DAMBRK guides the user through all aspects in developing a model.


Unmatched Graphics

BOSS DAMBRK displays over 30 different presentation-quality graphs, including an initial conditions plot, flood inundation map, hydrograph plots, summary hydrograph plots, time-history plots, and 3D river valley plots, allowing you to quickly evaluate your work. The user can select any or all of the graphs for output and let the software print the selected graphs one after another. Prior analysis graphs can be automatically superimposed upon current analysis graphs, allowing easy comparison of results such as dam failure versus non-failure hydrographs. Furthermore, all input, including cross-section geometry, can be viewed graphically during data input, allowing the user to quickly examine the modeling data for input errors.
BOSS DAMBRK includes the BOSS DIG™ (Device Independent Graphics) driver which allows the graphs to be printed on any supported laser printer, plotter, or dot-matrix printer. Or the graphs can be exported in any of several common graphic file formats, allowing you to import these graphs into many different CAD systems and word processors. The BOSS DIG driver also supports over 150 different display adapters, allowing you to view the graphs at the maximum resolution your display hardware supports.
BOSS DAMBRK can output its graphics to nearly any printer or plotter, or they can be exported to AutoCAD or MicroStation.

Lots of Help

Wherever you are in BOSS DAMBRK, extensive context-sensitive help is available to assist you through any difficulty. And with over 450 pages of professional documentation, including illustrations and complete example problems, you can be productive immediatelyóeven if you are a beginner.
BOSS DAMBRK includes extensive, context-sensitive on-line help to aid the user in defining a model.




The BOSS DAMBRK Model

BOSS DAMBRK is an enhanced version of the NWS DAMBRK model. The software has been compiled to take advantage of the 32-bit architecture of the 80386 and larger microprocessors, enabling BOSS DAMBRK to run more than two to three times faster than the NWS version. Floating point exception errors are recognized, allowing the user to recover from most non-convergent solutions. In addition, the model size has been increased over that of the NWS version, from 700 to 1,200 time-steps, from 90 to 120 user-defined cross-sections, and from 200 to 300 total (including automatically interpolated) cross-sections. For extra-large models, a 3,000 time-step, 300 user-defined cross-section, 2,000 total cross-section Professional Version of the program is available.
BOSS DAMBRK can analyze up to 10 dam and/or bridge structures in a single analysis. Subcritical, supercritical, and mixed flow regimes are supported. Linear and non-linear piping or overtopping breach developments can be specified at a dam structure, along with constant or time-dependent turbine flow and a variety of spillway types. Complex sloping dam crests and bridge decks can be analyzed. Explanatory notes can be attached to individual cross-sections, allowing field observations to be included with the analysis output.

BOSS DAMBRK can model complex subcritical, supercritical, and mixed flow hydrodynamic events and dam failures.



BOSS DAMBRK represents the latest understanding in dam failures and the use of hydrodynamic theory to predict dam-break flood wave formation and routing. The program can consider the effects of reservoir inflow, breach formation, spillway and turbine flow, downstream tailwater elevations, valley storage, frictional resistance, and lateral inflows and outflows. BOSS DAMBRK will report the flood wave travel time, time to flood stage, time to peak elevation, and the corresponding water surface elevations.
The BOSS DAMBRK database engine allows any entered cross-section to be used as a template for defining new cross-sections. This significantly shortens the time required to enter a large model by allowing the user to define characteristic template cross-sections, and then quickly propagate new cross-sections up and down-stream. Also, the program simultaneously supports both imperial and metric (SI) units, allowing the user to switch from one unit of measurement to the other at any time.
