摘要：	The Federal Highway Administration (FHWA) has been a leader in the development of two-dimensional (2D) computer models of surface-water flows, which provides a level of detail and accuracy not previously available to highway hydraulic engineers. In 1994, FHWA collaborated with the Engineering Computer Graphics Laboratory at Brigham Young University, which was reorganized to form the Environmental Modeling Research Laboratory (EMRL). The interface to the FHWA's 2D, depth-averaged, Finite Element Surface-Water Modeling System (FESWMS-2DH) and corresponding tools were made available as part of the Surface-Water Modeling System (SMS) in Version 4.0, which was released in 1995. Tools created for use with 2D finite element surface-water models generated an interest in the development of tools for creating 1D data and for visualizing 1D results in two and three dimensions. Therefore, an interface for graphical interaction with 1D cross sections was developed to support FHWA's Water-Surface Profile (WSPRO) computer model. The WSPRO computer model is used by hydraulic units in many state highway agencies to accomplish their routine water-surface profile computations. This interface was developed and made available in SMS Version 5.0, which was released in 1997. This article describes the methods and tools to perform numerical hydrodynamic analysis using SMS with FESWMS-2DH and WSPRO. The purpose of the article is to provide a greater awareness of state-of-the-art methods for modeling complex surface-water flows. The simulations are cost-effective and provide realistic solutions to complex problems commonly encountered by hydraulic engineers.
