A Comparison of the One-Dimensional Bridge Hydraulic Routines from HEC-RAS, HEC-2 and WSPRO.
Abstract
The hydraulics of flow though bridges is an important aspect of computing water surface profiles. The computation of accurate water surface profiles though bridges is necessary in flood damage reduction studies, channel design and analysis, and stream stability and scour evaluations. There are several one-dimensional water surface profile computer programs available for performing this type of computation. The most widely used of these programs are HEC-2 (HEC, 1991) and WSPRO (FHWA, 1990). The Hydrologic Engineering Center (HEC) has recently released a new program for computing one-dimensional water surface profiles, called HEC-RAS (HEC, 1995). The purpose of this study was to evaluate the effectiveness of the new bridge hydraulics routines in HEC-RAS at sites with extensive observed data, and to compare HEC-RAS to HEC-2 and WSPRO, with respect to bridge modeling performance.
