Tidal Flow in Exponentially Varying Estuaries
Estuaries with negligible freshwater flow and insignificant diurnal inequality are considered. With flow resistance according to Manning's formula, and governing equations...

Weight Optimization of Plane Trusses
Optimization of topology, geometry, and cross-sectional properties from a discrete table of sections employing code allowable stresses is demonstrated on plane truss structures. A modified...

Continuously Supported Cylindrical-Conical Tanks
The bending effects in the shell arise from two primary sources: (1) the radial forces applied through the ring stiffeners; and (2) the geometrical discontinuity at the cylindrical-conical...

Ultimate Strength of Rectangular Compression Members without Tensile Strength
In a 1971 paper by Yokel, he presented an analysis for the ultimate load of eccentrically loaded compression members of rectangular cross section with no tensile strength. This paper extends...

Longitudinal Dispersion in Sinuous Channels
The longitudinal spreading of tracer solution and the distribution of velocity are investigated experimentally in a laboratory flume having a series of 13 uniform bends in alternating...

Turbulent Flows Past Boundaries with Small Streamwise Fins
An experimental investigation was conducted to determine the effect of small streamwise fins on the average boundary shear stress of turbulent flows in conduits. The experiments were performed...

Prediction of Mixing Lengths for River Flow Gaging
An analytical solution of the diffusion equation is used to determine criteria for use in river flow gaging by the dilution method. The method advanced in this paper allows the mixing...

Simulation in Watershed Planning
Hydrologic and hydraulic simulation is an effective technique in comprehensive watershed planning and in subsequent plan implementation. The need and rationale for simulation are considered,...

Solutions for Lateral Outflow in Perforated Conduits
Many applications in varied fields of engineering design require a uniform discharge in a perforated conduit. This paper gives general solutions for obtaining a uniform lateral outflow,...

Design Criteria for Submarine Pipeline Crossings
This laboratory investigation of pipeline crossings of alluvial streams shows that the rate of scour above the pipe varies as the dimensionless shear stress which is a function of the...

Structural Designs for Bounds on Dynamic Response
An upper bound on the displacement at a particular point on an elastic beam resulting from impulsive loading may be established. For a given volume of material in a beam of sandwich cross...

Taper Cantilevers with Varying Distributed Loads
Many investigators have considered the problems of cantilever beams undergoing large deflections. Barton and Bisshopp and Drucker solved exactly a cantilever carrying a concentrated load...

Inelastic Buckling of Rings with Residual Stresses
Circular rings are commonly fabricated by cold rolling long straight bars of desired cross sections to the required radii and then completing them with a single butt weld. This process...

Cantilever Cylindrical Shells under Assumed Wind Pressures
A complete analysis is presented for the problem of cantilever cylindrical shells (clamped at the base and free at the top) subjected to wind pressures. Donnell's shell theory...

Open-Channel Flow Equations Revisited
Equations of continuity, momentum, and energy in integral form are formulated herein by integrating over the cross section the corresponding equations for a point and then transformed...

Optimal Plastic Design for Bending and Shear
In optimizing flexural systems (such as beams, frames, and grillages) of continuously varying cross section, most authors assume that the specific cost of the member is a function of the...

Large-Deflection Spatial Buckling of Thin-Walled Beams and Frames
The potential energy expression and the (14 by 14) stiffness matrix of a straight thin-walled beam element of open asymmetric cross section, subjected to initial axial force, initial bending...

Planning Criteria for Bikeways
The transportation planning process is examined including developing master plans and organization for planning and implementation. Guidelines are presented that help the professional...

Regime Equations and Tidal Inlets
Selected regime equations for stable channel cross-sectional areas are compared to an empirical relationship for stable tidal inlet areas. Using an equivalent steady discharge to represent...
