Flow and Sediment Transport in Curved Channels with Nonuniform Bed Material
Described is a scheme for controlling the exchange of grain sizes between bed and bed load in a curved alluvial channel. The scheme is an integral part of a model for simulating spatial...
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...
Automated Control for Central Arizona Project Distribution Systems
Computer based automatic control for three extensive open channel water distribution systems is described. Radio telemetry allows a central computer to execute control logic at individual...
Algorithms for Automatic Control of Diversion Dams
The application of local automatic control for the releases from a diversion dam that has intermittent river inflow is limited. For this case, it is better to install a remote monitoring...
Trash Busters ? A Comparison of Screening Structures for Irrigation Systems
Several irrigation districts in the Pacific Northwest have recently installed screening structures for use in removal of trash from canals, rivers, or reservoirs. Some of the screens have...
Water Supply and Sewage Disposal: Shanghai, China
This paper describes a joint research effort which took place between the Shanghai Bureau of Environmental Protection, Tsinghua University (Beijing), and the University of Michigan. The...
Garrison Diversion Unit?An Example of United States-Canada Cooperative Investigation
Canada and United States have cooperated in the investigation of disputed international waters on numerous occasions. The study of the Garrison Diversion unit is an example of an exhaustive...
The Changing Objectives of Garrison Diversion Unit
Construction of the 101,000-hectare initial stage Garrison Diversion Unit was authorized in August 1965 as a feature of the Pick-Sloan Missouri Basin Program for irrigation and other purposes....
Analysis of Freshwater Distribution System at the Long Beach Naval Complex
This account of the evaluation of freshwater pipelines at California's Long Beach Naval Complex discusses current methods for assessing the condition of damaged water lines....
Modeling Erosion and Sedimentation in Irrigation
Sediment yield and erosion modeling approaches for sprinkler and surface irrigation are discussed. Empirical approaches, such as the ULSE, and other regression approaches and their applicability...
Irrigation and Groundwater Quality in the South
Impact of irrigation trend, water table fluctuations, crop management, and tillage systems on groundwater quantity and quality of the southeast (Alabama, Florida, Georgia, and South Carolina)...
Geotechnical Construction Control Data Base Package
A data base can be defined as pieces or groups of data stored together in an orderly form such that access to all or any part of the data can be readily accomplished. A computerized data...
Project Cost Control for Heavy Equipment
Some concepts and methods of project cost control for heavy equipment have been defined, which include methods, effectiveness, outside repairs, and the resulting management information,...
Teaching Experiment in Real-Time Construction Data Acquisition
This paper describes an experiment used in an undergraduate civil engineering course to familiarize students with interfacing electronic instruments mounted on a construction machine to...
Rapid Identification of High Risk Building in Seismic Regions Using Expert Systems
Seismic risk evaluation is a complex problem because it involves many factors such as ground motion, ground failure potential and structural performance with great uncertainties. Many...
The Promise of Supercomputers
This paper briefly reviews the classification and general architecture of supercomputers: their capabilities, promise, current and projected limitations are considered. The author reviews...
CAPPS: Custom Architectured Parallel Processing System
CAPPS (Custom Architectured Parallel Processing System) is under development at Paragon Pacific Inc. , Torrance, CA, for the solution of computationally intensive engineering problems....
Supply Side Engineering
In New Jersey, the Hackensack Water Co., a private utility, and the North Jersey District Water Supply Commission, a state agency, are jointly completing Wanaque South, a $151 million...
An Integrated Approach to Structure and Control Design of Space Structures
In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints...
Optimum Seismic Structural Design with Tendon and Mass Damper Controls and Random Process
This paper describes the optimization of structural weight for seismic structures implemented by active control systems. The instantaneous open-loop optimal control algorithm is used for...
