Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
Coronarization of the Autonomous Water pump
The conventional hydraulic pressure multiplier has been successfully used by Belgian technician Robert Houman (1986) to provide a dependable source of water supply to the NATO-base at...
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...
Hydraulic and Scour Analysis for Muitiple Crossings of the Salt River, Phoenix, Arizona
Two new freeway systems currently being designed for the Phoenix metropolitan area, the East Papago Freeway and the Outer Loop Highway, will both cross the Salt River within a one mile...
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...
Major Sedimentation (Erosion) Issues and Ongoing Research and Developments at the USDA-ARS
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...
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...
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...
Top Projects 1990
A dam, a bridge, an expressway, an interchange, flood control improvements, wastewater treatment and a dredged material containment embankment round out the 1990 Outstanding Civil Engineering...
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...
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...
