Measured Performance of a Laboratory Culvert
This study shows that the behavior of a soil culvert system can be modeled by a linear finite element program and a mathematical solution of a hole in an elastic sheet reinforced by a...

Estimating Local Scour in Cohesive Material

Soil-Structure Analysis and Evaluation of Buried Box Culvert Designs

Computer Analysis of Newtown Creek Culvert
The design of corrugated-metal buried structures with spans of as much as 25 ft to 50 ft (7.6 m to 15 m) has been largely empirical. Finite element methods of analysis using computers...

Expansive Roadbed Treatment for Southern Africa

Behavior and Design of Long-Span Metal Culverts
The interaction between flexible metal culverts and the surrounding backfill is examined by means of finite element analyses that simulate the placement of backfilling and subsequent application...

Arch Culvert Footing Movements
A flexibility approach is combined with a neutral point (elastic center) analysis to assess effects of differential footing displacements on the structural behavior of arch culverts embedded...

Arch Culvert Research—Phase 3
A 22-ft (6.7m) arch culvert embedded in a highway embankment under 191 ft (58 m) of overfill was instrumented to evaluate the relative behavior of two structural sections subjected to...

Optimal Design of Culverts under Uncertainties
In the design of highway drainage culverts there are many uncertainties involved in addition to the normally considered hydrologic uncertainty due to the randomness in flood and rainfall...

Measured Performance of Newtown Creek Culvert
Increasing use is being made of corrugated-metal buried structures for culverts and grade separations with spans exceeding 25 ft (7.63m). Recently developed analytical design procedures...

Design and Construction of Long-Span Metal Culverts
Long-span metal culverts are built of corrugated-metal plates bolted together. They have spans exceeding 15 ft. Principal applications include use as drainage structures, grade separations,...

Culvert Design and Channel Erosion

Direct Solution to Problems of Open Channel Transitions
Existing methods of solving problems of open channel transitions involve trials-and-error solution of higher degree equations and no direct solutions are available in technical literature....

Flood Management for Small Urban Streams
Experiences in Princeton, N.J. are drawn on to analyze flood problems of small urban streams, including building in flood plains, increased floods due to urbanization, and accentuated...

Stratified Flow in Great Salt Lake Culvert
A causeway has effectively divided the Great Salt Lake in Utah into two lakes having different water-surface elevations and different densities. Exchange between the two lakes is by seepage...

Highway Fill — A Broad-Crested Weir
Hurricane Agnes in June, l972, destroyed the bridge over the Middle Patuxent River in Maryland which had suffered damages from several other storms. Replacement costs had to be kept low...

Stresses in Shallow Elliptical Tunnel
Structural-soil composite bridge systems utilizing corrugated steel culvert lines have recently become quite popular. In a previous page on long-span flexible elliptical culverts, one...

Model Study of Culvert Energy Dissipator
This paper describes some experiments with a model of the Basin VI energy dissipater with a square culvert. The model and experimental procedure are described, the experimental results...

Optimum Size of Equipment
Generally speaking, equipment of greater capacity yields lower unit costs than does equipment of lesser capacity. However, this is not true when the equipment is employed in an operation...

Improved Design of Highway Culvert
New culvert design procedures, incorporating improved inlet concepts, make significant construction savings possible through hydrauically efficient use of the culvert barrel. Two representative...
