Hydraulic Reliability of Urban Water Distribution Systems
Conventional planning and design approaches for urban water distribution systems consist of trial and error procedures to select piping network configurations, pipe sizes, storage capacities...
Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
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....
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...
Organization Design of a Water Resources Institution
An overview of the field of organization design is presented along with a brief description of major macro-organization design theories. Utilizing this information, four water resources...
Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...
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...
Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...
Submerged Vanes for Sediment Control in Rivers
A procedure is developed for a rational design of a system of submerged vanes for depth control in alluvial-river channels. The vanes are vertical, small-aspect ratio foils installed on...
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...
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...

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...
