Finite Element Model for Backwater Computation

Two-Dimensional Analysis of Backwater at Bridges
A two-space dimensional mathematical model of computing steady flow distributions and water levels near contractions in natural waterways (e.g., highway bridges) is developed. The two-dimensional...

Comparison of Bridge Backwater Relations
A previously developed subcritical (submerged) flow analysis for open channel constrictions has been shown to be generally applicable to computing backwater due to bridges, whether the...

Computing Backwater at Open Channel Constrictions
A previously developed subcritical (submerged) flow analysis for open channel constrictions has been modified to provide an improved technique for computing the backwater resulting from...

Backwater Effect of Submerged Sills
In designing these sills one would like to know the various damming effects that could be achieved if the components of the sills are arranged in different configurations. The experiments...

Nonuniform Flow in Flat Rectangular Channels
Nonuniform flow is possible in flat open channels and the surface profile of flow in such a channel is always in the form of a backwater curve. The present practice for backwater profile...

Bridge Backwater in Wide Valleys
A method is presented for calculating the longitudinal water surface profile in the reach of a river in flood which is disturbed by the presence of the bridge and embankment fill. A variety...

Characteristics on M1 Backwater Curves
An analysis of M1 profiles with Froude number as a reference parameter is made. A total of 182 M1 profiles in rectangular, trapezoidal, triangular, and parabolic channels are studied....

Characteristics of the Backwater Curve
The profiles of over forty Ml curves in rectangular channels are examined. The ranges of variables covered are: n, from 0.012 to 0.050; breadth-to-depth ratio, 2, 10, and infinity; and...

Solving the Equations of Uniform Flow
All realizable hydraulic profiles associated with the uniform flow of liquid in an open channel are expressible in terms of three simple integrals. The fifteen profiles fall naturally...

Travel Time of Waves in Backwaters
Time of travel of elementary waves in prismatic channels with gradually varied flow is expressed by two parametric equations. The first of these equations gives the travel time over a...

Hydraulics of Single Span Arch Bridge Construction
Series of model tests were run for condition of no skew, no eccentricity, and no entrance rounding; generalized backwater equation is presented, by means of which backwater superelevation...

Water Surface Profiles in Irregular Natural Streams
Simple, practical method is proposed for computation of water surface profiles; method is advantageous when several backwater profiles must be determined in channel; assumption is that...

Tolkmitt's Backwater and Dropdown Curve Tables
Tables and formulas, published originally by G.TOLKMITT, are presented in slightly enlarged form, for computation of backwater and dropdown curves for channels of parabolic section; use...
