Longitudinal Stresses in Buried Pipes
Longitudinal stresses are inevitable in buried pipes even in pipes with gasketed joints. Longitudinal stresses in any pipe section are cumulative. They include stresses due to soil friction...
SULF.BAS, an IBM PC Sulfide Prediction and Corrosion Analysis Program for Sanitary Sewers
'SULF. BAS' is a Basic language computer model which predicts sulfide buildup and corrosion protection required in a sanitary sewer system. The prediction is...
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)...
Response of Buried Flexible Plastic Conduits Under Loading
Structural performance of 75 mm and 100 mm diameter plastic conduits embedded in Lloyd clay were examined experimentally in a laboratory soil bin, and numerically by the finite element...
Large Diameter Plastic Pipe Design
This paper presents a rationale for the design of large diameter plastic pipes for gravity flow applications. This procedure, applicable for all plastic pipes, adapts state-of-the-art...
Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...
Design of Non-Pressure Very Flexible Plastic Pipe
There is considerable debate about the correct structural design procedure to be used for very flexible plastic pipe (VFP) - typically glass-fiber reinforced pipe (GRP), reinforced plastic...
Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
Microcomputers in Domestic Water System Evaluation
Water system hydraulic network analysis can be accomplished rapidly and accurately using microcomputer systems affordable by engineering firms and staffs of major water utilities. Simulations...
A 1-D Saltwater Intrusion Program on the IBM-PC
A one-dimensional finite element program has been developed for use on the IBM-PC as an aid to teaching groundwater hydrology to students. The program uses linear elements and the Galerkin...
Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
A Two-Dimensional Numerical Model of Thermal Discharges in Coastal Regions
This paper describes a two-dimensional numerical model of thermal discharges in coastal regions. The model uses potential flow theory to calculate the ambient velocity field of the coastal...
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...
Flowfield Analysis with a Workstation
An engineering analysis workstation has been developed to expedite flow analysis. The workstation couples a microcomputer, a powerful numerical equation solver, and a versatile graphics...
South Branch Rockaway Flood Water Study
The paper reports on a study to analyze in detail various methods of storm water management. The technical studies were carried out in an actual watershed setting to arrive at a recommended...
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...
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
