Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Assessment of Drought Restriction Needs in New Jersey
Due to insufficient rainfall and related runoff during the spring of 1985, the Passaic and Hackensack River Basins in northern New Jersey and related storage reservoirs therein were able...
Classification and Behavior of Meander Migration
Meander migrations on the Mississippi River between Cairo, Illinois and Baton Rouge, Louisiana for the time period between the years 1765 and 1930 were classified into six categories based...
Management Strategy
Meanders of sinuous streams are often cut off by natural action or by man in order to improve conveyance or navigability. Cutoff bendways, as long as they remain aquatic, provide extremely...
Effect of the Fluid Velocity on the Biofilm Development
In order to get basic information concerning the application of a biological treatment to the ammonia nitrogen removal from drinking water, we considered the relation between the biofilm...
A New Methodology for Modelling Water Pipe Breaks
A new methodology for modelling breaks in large diameter cast-iron water pipes is proposed. The need to consider two separate stages of deterioration (early stages with fewer breaks and...
A Computer Model for Oil Slick Transport in Rivers
A computer model for simulating oil slick transport in rivers is presented. In the model the effects of advection, spreading, evaporation, and dissolution on the transformation of an oil...
Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...
Development of Two- and Three-Dimensional Modeling Systems for Open Channel Flow and Sedimentation
Two- and three-dimensional numerical modeling systems have been developed to address questions of open channel flow and sedimentation for the Corps of Engineers. These systems are complete,...
Physical Habitat Simulation and the Moveable Bed
One objective of an instream flow analysis is to quantify a flow that will maintain the existing channel and/or flush fine material from the bed. Five empirical approaches to determine...
Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...
Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...
Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...
Microtunneling: No Pipe Dream
Microtunneling machines developed in Japan and Germany can help install pipes, ducts and cables without disrupting urban activities at street level. A microtunnel is defined as having...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...
Three-Dimensional Boundary Element Techniques for Moving Boundary Problems
The boundary element method (BEM) is a powerful numerical method well suited for a wide variety of engineering problems. The numerical computations are performed only on the boundary of...
Hydrologic Simulation for Reservoir Development
Potential changes in the Manasquan River basin hydrologic budget were assessed with the Hydrological Simulation Program in Fortran (HSPF). The HSPF results were used to assess the reliability...
