Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...
Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...
Corps of Engineers Sediment Management Program
The existing sediment management program includes sediment investigations of reservoir, river and levee projects; gathering and maintaining sediment load records; providing sediment investigation...

The U.S. Department of Agriculture, Agricultural Research Service (ARS) has research programs designed to produce techonology with which to predict, measure, and control erosion and sedimentation...
River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...
CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) overtopping protection systems have been designed for and will be installed on three small embankment dams along the Blue Ridge Parkway. Based on recent field...
Diversion Closure Gate Schemes Used on B.C. Hydro Dams
Over the last 25 years B.C. Hydro has designed, built and has operated a number of large dams and continues to do so. This paper describes the design, erection and operating experiences...
Experiences With a Supercomputer
The advent of ever faster and ever larger computers is opening new areas of scientific study. Within this computational revolution, however, are real people trying to cope with the vagaries...
Microcomputer Applications in Transportation III
This proceedings consists of papers presented at the International Conference on Microcomputers in Transportation which was held on June 21-23, 1989 in San Francisco, California. They...
Modeling Not By the Numbers
A model is likely to be the tool for making predictions of the ecological impact of an engineering decision. However, ecologists often find it difficult under pressures of time and lack...
Landfill Liner Quality
Landfill liners are being made with new synthetic materials, materials which may be beyond the knowledge of the engineer in charge of the landfill construction project. Engineers need...
The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...
A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Franchising for the Future
Franchising is no longer reserved for hamburger stands or quick print photo processors. Now engineers may decide to join lawyers and dentists in future franchise operations. In today's...
Lower Granite Fish Guidance Efficiency System Model Study?Snake River, Washington
With the annual migration of adult salmon up the Columbia and Snake Rivers and the migration of their offspring (juvenile salmon) downstream to the ocean, new problems have developed with...
An Update on the U.S. DOE Ocean Energy Program
This paper summarizes recent research accomplishments of the program and provides a synopsis of planned activities leading to a Net Power-Producing Experiment (NPPE), to be conducted at...
Ocean Energy Activities in Europe
This paper reviews European research and development in wave energy, ocean thermal energy conversion (OTEC), and ocean tidal power. For each technology, a country-by-country summary (in...
Experimental Research and Parameters Optimization of a Prototype OWC Wave Power Device
The paper presents the experimental research and parameters optimization of a prototype oscillating water column (OWC) wave power device being built in China by Guangzhou Institute of...
Pre-Experiments of OTEC Experimental Facility for Ocean-Based Mariculture-OTEC Pilot Plant Houyou
The ocean-based mariculture-OTEC pilot plant 'HOUYOU' was completed in March, 1989 and the at-sea test in Toyama Bay was carried out from July 18th until September...
OTEC's subsurface discharges of Deep Ocean Water: Modelling Their Effects on the Primary Production
The French project of a shore-based OTEC pilot plant (5 MW) at Tahiti gave the opportunity of simulating the ecological effects of a small, man-made upwelling in coastal-tropical oligotrophic...
