There is no need for the user to struggle with cumbersome, cryptic, error-prone input card files. In addition, existing HEC-2 models can be directly imported. BOSS HEC-RAS is very easy to use, allowing the user to quickly define a river model to be defined. All graphics can be viewed during data input, enabling the user to quickly examine the model for input errors. Total user control is provided over line color, line width, and line type.
Graphic plots can be output at any user-defined scale.
Axis labels can be redefined, and the user can select what variables to display on the plots. The program supports all Microsoft Windows output device drivers, allowing the graphs to be printed on any laser printer, plotter, or dot-matrix printer. The professional documentation includes discussions on the theoretical basis of the model, data requirements, optional capabilities, bridge and culvert hydraulics, floodway computations, as well as a complete description on how to use the software. HEC-RAS' model checker will check over the specified input data. If it encounters an error with the input data, it will explain what is wrong and how you can correct it.
