Concrete Pipe Culvert Behavior—Part 1
An 84-in. (2.14-m)-diam., reinforced concrete, dummy pipe culvert, with a 1,000-D load rating, was buried under 136 ft (41.5 m) of highway embankment. Six 40-ft (12.2-m)-long zones were...

Concrete Pipe Culvert Behavior—Part 2
An 84-in. (2.13 m)-diam., reinforced concrete, dummy pipe culvert, with a 1,000-D load rating, was buried under 136 ft (41.5 m) of highway embankment. Six 40-ft (12.2-m)-long zones were...

Optimal Design for Highway Drainage Culverts
Economic risks are directly considered in an optimal design procedure for box culverts. Flood related losses are computed on a probabilistic basis to derive economic risks for box culvert...

Swimming Performance of Arctic Grayling

Digital Computers in Circular Culvert Design
As circular culverts may have sections of different slopes, lengths, and pipe sizes, flow profile and hydraulic jump calculations are extremely tedious and time consuming. A digital computer...

Concrete Arch Culvert Behavior-Phase 2
An arch culvert, under a 240-ft. (73-m) embankment, was tested to assess influence on structural behavior of four methods of backfilling, including Method A, employing well-compacted structure...

Steel Highway Accessory Structures
Highway accessory structures are essential for full utilization and continued service of modern highways. Culverts, retaining walls, bridge flooring and forms, guardrail, signs and lighting...

Energy Dissipators for Large Culverts
A model study of a hook-type energy dissipator basin has shown hooks to be an efficient and economical means of hydraulic energy dissipation for large culverts. The tests showed the hook-type...

Nonenlarged Box Culvert Inlets
The effect of variation in the dimensions of beveled leading edges on the discharge capacity of box culvert inlets of rectangular cross section is investigated. It is demonstrated that...

Structural Behavior of Concrete Arch Culvert
Field studies were made of an arch culvert embedded in a deep embankment and surmounted by layers of straw. Quasitheoretical internal stresses resulting from measured soil pressures acting...

Flexible Culverts Under High Fills
The possibility of predicting the load distribution on the culvert if the fill material, base material and method of fill are specified, is discussed. The additional feature of the deformation...

Harvard Gulch Flood Control Project
The planning, design, and construction of a major urban flood control project is presented. Emphasis is placed on the flood hydrology investigations used as a basis for sizing of the culverts,...

Forces on Rigid Culverts under High Fills
The forces acting on the barrel of a rigid culvert due to the dead load of a high fill may depend on the construction method, the presence of organic material, the material of the earth's...

Flow in Culverts and Related Design Philosophies
The determination of the performance of a culvert is difficult, but the performance must be known before the capacity can be computed using well-known equations. A classification of the...

Philosophy Of Service Life In Culvert Design
The philosophy of service life in the design of culverts has changed over the years. With the improvement and enlargement of our highway system, culvert costs are significant and the service...

Hydraulic Efficiency In Culvert Design
Although all of the equations required for the hydraulic design of culverts are well-known, the determination of which equation applies to a particular situation is difficult to determine....

Philosophy Of Culvert Design
Culvert design is traced historically from a philosophic viewpoint, beginning with the nonprofessional conceptions of road foreman and stone masons 60 yr ago. Centralization of the road-building...

Tapered Inlets for Pipe Culverts
The performance of pipe culverts on steep slopes with tapered inlets is, in general, sensitive to the presence of air-carrying vortices over the inlet. Under such conditions, an area of...

Transitions for Canals and Culverts
Results of large-scale model studies of variations in open-type and closed-conduit-type inlet and outlet transitions for small canals and culverts are presented. Losses for open transitions...

Navigation Locks: Filling and Emptying Systems for Locks
Three basic criteria are used in the design of lock filling and emptying system: (1) Lockages must be accomplished in the shortest possible time; (2) disturbances in the lock chamber must...
