The program can simulate flow around/through various It calculates solutions for both subcriticalĪnd supercritical flow profiles. Varied flow in natural or man-made channels. The current version of HEC-2 calculates water surface profiles for steady, gradually The FHWA procedures wereĪdded to HEC-2 by Dodson and Associates of Houston, TX. Highway Administration's (FHWA) culvert procedures. (Version 4.6) included the capability to simulate culvert hydraulics using the Federal Program’s first release, addition of new features and improvements have prompted the

Second in a series of generalized computer programs issued by the HEC. Program was revised and released as HEC-2, Water Surface Profiles. Modern computational techniques for hydraulic analysis (USACE, 1990).

This program represented a significant step in the development of Possessed the capability of computing water surface profiles in channels with irregularly Name "Backwater Any Cross Section." The Backwater Any Cross Section program In 1966, the HydrologicĮngineering Center (HEC) released the first FORTRAN version of HEC-2 under the Army Corps of Engineers, Tulsa District office. This early version was developedĪt the U.S. The original computer program HEC-2, Water Surface Profiles, stemmed from a step-īackwater program written by Bill S. The modelsĪddressed herein include: HEC2, UNET, WSPRO, HEC-RAS, Ad-ICPR, SWMM, and Search address only the more commonly available / popular models (i.e., non-proprietary)Įmployed for this specific application (determination of bridge hydraulics). Models for examining flow in open channels and through bridge crossings. Survey of the literature revealed a number of different Some one-dimensional models attempt toĪpproximate the effects of transverse variation in roughness and velocity through the Not explicitly consider transverse effects. Vary only in the streamwise direction (USACE, 1993). The term one-ĭimensional derives from the model assumptions that the stage, velocity, and discharge Single reaches or complex networks of interconnected channels. One-dimensional open-channel flow models can simulate steady or unsteady flow in

* These models were/are free to the public. The models discussed below include the following: As such, the literature review concentrated on three areas: a shortĭescription of the commonly applied one- and two-dimensional models, case studies forĮach of the models, and comparison articles that contrasted one- and two dimensional Revealed that very little literature exists that contrasts these two types of models for suchĪ specific application. Models at bridge crossings under a wide variety of conditions. The main objective of the literature review was to compare and contrast the relativeīenefits/difficulty between the application of one-dimensional and two-dimensional

Transportation and the Federal Highway Administration. To consist of not only a review of the current literature, but also a survey of the engineersĬurrently performing bridge hydraulic analyses for the state Departments of Given the diverse requirements of this task, the procedure for successful completion had Identifying and characterizing the site conditions and design requirements that may affect — from actualīridge sites for the selection tool example application. Measured event flows and stages, survey data, boundary conditions, etc. The second objective includes identifying data sets — which contained

The first objective included identifying the most commonly employed one- and two-ĭimensional numerical modeling software for examining hydraulics through bridge The purpose of a literature review and survey of the state of the practice was multifold.
