Construction-Induced Dynamic Pressure and Corresponding Impact Factors for Pipelines
The Bureau of Reclamation, U. S. Department of the Interior, conducted a study which measured pressure exerted by construction scrapers on a rigid, buried, instrumented concrete slab....
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...
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...
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...
Large Basin Runoff Forecasting on Small Computers
The Great Lakes Environmental Research Laboratory (GLERL) developed a semiautomatic software package for making deterministic outlooks of basin moisture storage conditions, basin runoff,...
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...
Reservoir Operation Simulation on Micro Computers
A reservoir operations planning model for a potential reservoir site on the Karadj River in Iran was developed utilizing a personal computer and a commercial spreadsheet package. The model...
Microcomputer Simulation of Jets and Wakes
Illustrations are presented for radial jets and for turbulent flows in the wake of circular cylinders. The paper illustrates the use and importance of low-cost computational tools in engineering...
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...
An Operational Dynamic Routing Model for Small Computers
The paper reports on a study to develop an efficient dynamic routing procedure that can be used on an IBM PC/XT microcomputer as the routing component in a comprehensive watershed simulation...
Floodplain Modeling for the Henry Street Basin
A study focusing on the primary conveyance system in the 5. 7 mi**2 Henry Street Drainage Basin in Hillsborough County, Florida was conducted to develop remedial measures for the control...
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...
Simulation of Marsh Growth Under Rising Sea Levels
A method for computation of the rise of a marsh surface is presented that includes the effects of tidal and sea level variations, aggregation and deposition of cohesive suspended sediments,...
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...
Simulating Flow in the Tidal Potomac River
A one-dimensional unsteady flow model has been applied to the tidal Potomac River, including its major tributaries and marginal embayments, between Washington, D. C. and Indian Head, Md....
Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...
