Experimental and Field Observation of Dynamic Behavior of Buried Pipelines
Cyclic torsion, axial pull-out, and bending data from experiments conducted on jointed utility pipelines buried at several depths are presented. It is found that linear relationships exist...

Dynamic Responses of Buried Pipelines
The dynamic responses of the pipelines are analyzed by the continuous mass matrix method by considering the soil as a bounded plane in which the pipeline is placed. The friction between...

Characterization of Soil Arching Above Buried Conduits
Conventional ways of assessing the effects of soil arching over buried conduits were examined by means of finite element analyses. It was found that neither of the conventional soil arching...

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...

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...

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...

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...

Real-Time Monitoring for Ohio Basin Water Management
The Ohio River Division (ORD) of the Corps of Engineers operates 77 reservoirs in this basin for the purposes of flood control, conservation, hydropower, low flow augmentation, water supply,...

Real-Time Monitoring and Flood Forecasting in Harris County, Texas
A new automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 90 sensors are automatically...

Geostationary operational environmental satellites (GOES) Data Collection Procedure?Ft. Worth District
The Fort Worth District Corps of Engineers is currently responsible for the daily operation of 22 federally owned reservoirs in Texas. This report describes this district's experience...

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...

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...

Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...
