Bri-Stars (BRIdge Stream Tube model for Alluvial River Simulation)

BRI-STARS Software | BRI-STARS Documentation

The BRI-STARS (BRIdge Stream Tube model for Alluvial River Simulation) model is a generalized semi-two-dimensional water and sediment-routing computer model that includes an integrated graphical interface. The model can be used to solve complicated river engineering problems with limited data and resources and is capable of computing alluvial scour/deposition for subcritical, supercritical, or a combination of water surface profiles that pass through critical depth. Unlike conventional water and sediment routing models, it is also capable of simulating the channel widening/narrowing phenomenon as well as local scour due to highway encroachments. It contains a subset of Federal Highway Administration's WSPRO subroutines for computing bridge hydraulics. The BRI-STARS software and associated manuals will be of particular interest to hydraulic engineers, bridge engineers, and fluvial geomorphologist involved with bridge scour evaluations, and modeling of general scour in alluvial streams in the vicinity of bridge crossings and highway encroachments. BRI-STARS is particularly useful for evaluating sites where contraction scour and/or effects of in-stream mining activities are a concern.

The BRI-STARS Software is available as an installable executable. The installation includes the program, sample data files, and utility programs.

The BRI-STARS User's Manual provides theoretical background on the methodologies used by the model as well as the formulations of governing flow and sediment routing procedures. Various records needed for the operation of the model, their description, format and sequential positioning within the data structure are given. Example applications as well as practical guidelines for the use of the model are presented.

The BRI-STARS Primer provides a brief description of the BRI-STARS model, installation and operation guidelines, the usage of the various utility programs within the package and an example application of the model. Detailed instructions for the use of utility programs included in the BRI-STARS package including their menu structures and their operations are given.
