Abstract
This report includes descriptions of three computer programs developed to enable practicing engineers to make use of the two-dimensional finite element model FESWMS-2DH for the analysis of scour at single opening bridges. Multiple opening bridges could be analyzed one opening at a time after using WSPRO to determine the division of flow for each opening. The executable versions of the programs are available. The program descriptions are as follows: PREFES is a preprocessor for FESWMS-2DH which is described in detail in the report. The program PREFES creates the finite element grid input file and various other files required to run FESWMS-2DH. It is designed to create close to the maximum allowable number of finite element nodes with the greatest node density through the bridge opening. This results in very precise flow modeling by FESWMS-2DH. Reliable estimates of angle of attack, velocity magnitude and approach depth can be obtained for scour calculations.
