HEC River Analysis System (HEC-RAS)
The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the...
An Improved Design of Fishways Under High Variation of Headwater
For the purpose of mitigating environmental impact, it is necessary to build fish passing facilities for fish migration when a dam is constructed on a river. But when the headwater variation...
Improved Hydraulic Features of the HEC River Analysis (HEC-RAS)
The Hydrologic Engineering Center (HEC) is in the process of developing a Next Generation (NexGen) of hydrologic engineering software. The goal in the area of river hydraulics is to develop...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Sedimentation and Remediation Aspects of Recreation Lakes
Relatively higher rates of silting in Lake Shafer, Indiana during the past few years have been a matter of concern to its owners, operators, and users. Potential causes for observed increases...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...

Lessons Learned from the Design, Construction and Operation of Hydroelectric Facilities
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...
Keeping Up With Computers
As computer hardware and software continue to grow in power and complexity, with new advances announced every day, many engineers wonder how to keep up with the rapid pace of change. When...
Restoring Freedom at the Capitol Dome
Early one morning last spring, a helicopter lifted that Statue of Freedom off its pedestal at the top of the U.S. Capitol Dome where it had stood undisturbed since shortly after the Civil...
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...
Reforming Japan's Public Works
Japan's public works bidding system has traditionally been dominated by money politics and industry collusion, which has served to keep out small Japanese companies as well...
Light at the End of the Chunnel
