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...
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 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...
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...
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...
Microcomputers and Design Codes: A Case Study
A microcomputer analysis of the thermal stress problem in reinforced concrete box sections was conducted. An explicit finite difference algorithm for a one-dimensional heat flow analysis...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....
The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...
