Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...
Design of Manning's-Rougness-Coefficient Study in New York State
Field-collected hydraulic data can be used to compute roughness coefficients for channels with different hydraulic characteristics. Suggested criteria for the design of a roughness-coefficient...
At-A-Site Mountain River Flow Resistance Variation
At-a-site variation in flow resistance is examined in the light of observations of an S-shaped velocity profile at relative submergences (d/D84)...
Evaluating Flow Resistance Using Height of Roughness Protrusions
On the basis of field measurements on the Sumava mountain rivers heights of roughness protrusions have been used for calculation of flow resistance. The result resistance equations, compared...
Flow Resistance of High-Gradient Gravel Channels
The flow resistance in terms of the friction factor for bank-full or high in-bank flows for 120 high-gradient gravel-bed rivers are examined. The friction factor f was divided into grain...
Step-Pool Streams: An Adjustment to Maximum Flow Resistance
An experiment was conducted to study the maximum flow resistance of step pool streams and the morphology of the steps formed from clastic materials. The step pool formation was qualitatively...
Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...
Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...
The Rest of the Best
Nominations for this year's Outstanding Civil Engineering Achievement Award ranged from a channel built to control flood waters to the construction of a wastewater pollution...
Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...
Lessons Learned from the Design, Construction and Operation of Hydroelectric Facilities
Northridge: Questioning Our Codes
The earthquake that struck Southern California at 4:31 A.M. Pacific Time on January 17, 1994 was responsible for 61 deaths, more than 9,000 injuries and $30 million in damages. From its...
Computer-Integrated Construction
Computers have been used quite successfully as replacements for manual drafting, but to stop there seriously underuses the potential of computer aided design. By using the computer's...
Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...
