On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...
New Developments in HEC Programs for Flood Control
Since the Hydrologic Engineering Center (HEC) started in 1964, the evolution has been toward packaged programs that perform a variety of computation options. Two examples are the flood...
Water Infrastructure: Research and Education Needs
Problems with infrastructure have received considerable attention but not much has been written about implications for research and education. Education and research should be aimed at...
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....
Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
The analysis of scour and deposition in Hansen Reservoir by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and...
Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...
An Optimization Model for Use in Analysis and Design of Wastewater Treatment Systems
The objective of present wastewater treatment plant design is to provide a cost effective processing system for a given waste-water. Generally each of the unit processes is designed to...
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...
Energy Dissipation in Small Canals
Two approaches are used for energy dissipation in channels. In the first, the water is allowed to drop, thereby converting potential energy to kinetic energy. This excess energy is then...
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...
Technology Transfer: Consultants and Counterparts
The results of an investigation into the transfer of technical knowledge between and among foreign consultants and their host country counterparts at two large-scale development projects...
Tunneling Around Ft. McHenry
The world's largest underwater tunnel was built out of sight and sound of Ft. McHenry. The 4,000 ft tunnel needed to take I-95 from shore to shore had to be extended to 7,200...
Utopia Under Glass
We stand within sight of the day when our reserves of fossils fuel will be inadequate to maintain the type of energy inefficient cities we have grown used to. This exercise in urban planning...
Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...
Highway Infrastructure
Opportunities for Innovation
Our national commitment to financing the rebuilding of America's highway intrastructure represents a very expensive, long term investment. The challenge facing highway engineers...
Reviewing for Potential Failure
The key to preventing structural failures is to examines them and develop systematic techniques for avoidance. One, called contingency analysis, starts with a what if process to decide...
Contractor, Businessman
The management side of running a construction firm is as important to its survival and growth as the technical activities. This article tells how a Cincinnati geotechnical contractor,...
