User's Primer for BRI-STARS (BRIdge Stream Tube Model for Alluvial RiverSimulation)

摘要

BRI-STARS (Bridge Stream Tube model for Alluvial River Simulation) model is ageneralized semi-two-dimensional water and sediment-routing model with an integrated graphical interface for solving complicated river engineering problems with limited data and resources. This model is capable of computing alluvial scour-deposition through subcritical, supercritical, and a combination of both flow conditions involving hydraulic jumps. Unlike conventional water and sediment routing models, it is also capable of simulating channel widening/narrowing phenomena as well as local scour due to highway encroachments. It contains a subset of Federal Highway Administration's WSPRO subroutines for computing bridge hydraulics. This User's 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 instruction for the use of utility programs included in the BRI-STARS package including their menu structures and their operations are given.
