Investigation of the Long-Term Creep Modulus for Buried Polyethylene Pipes Subjected to Constant Deflection
The tests reported in this paper are simulating the stress relaxation in constantly deflected pipe rings of various high density and medium density polyethylene grades. The pipe rings...
Long Term Deflection of Buried Plastic Sewer Pipes
During the 70's and the early 80's a research program has been carried out in Sweden regarding the long term behaviour of buried plastic pipes. The program has...
Determining the In-Place Density of Soils Using the Sleeve Method
The sleeve method of determining the in-place density was developed by Bureau of Reclamation field personnel for cohesionless, fine, gravel soils used for pipe bedding when other methods...
Numerical Simulation of Soil-Pipeline Interaction in a Ground Subsidence Zone
In this paper, the flexural interaction between a buried pipeline and the surrounding soil is examined by employing a combined boundary element-finite element scheme. The flexural interaction...
Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...

Microcomputers in Highway Drainage Design
This paper discusses some of the benefits and uses of microcomputers in highway drainage design and discusses the programs presently being developed. Subjects covered include hydrologic...
Computational Model for Computing Dune Erosion
This paper summarizes the development of a computer model for determining potential beach and dune erosion along the Florida Panhandle. The results have been used as a guide in delineating...
Real-Time Flood Forecasting on Small Computers
A real-time, rainfall-runoff, flood forecast model, developed by the Corps of Engineers Hydrologic Engineering Center (HEC), was applied to two of tributary basins in the Ohio River System....
A Microcomputer System for Processing Analog Hydrologic Data
Microcomputer software was developed to digitize, filter, and view data from analog charts of gate operation and water level before being transmitted to a mainframe computer for data base...
Survey of Computer Use in Hydraulics and Hydrology
The surveyed population consists of the 58 member firms of the Consulting Engineers Council of Colorado practicing in the area of water resources. 90 percent of these firms use computers...
Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
