Next-Generation Local Scale Hydromet Forecasting System
Research and development work is being conducted for the National Weather Service on a new-generation flash flood monitoring and forecasting computer workstation. The workstation represents...

Hydrologic Aspects of Flood Warning?Preparedness Programs
A reliable flood-threat recognition system is a vital component of a sound flood warning-preparedness program. Fundamental questions associated with the development of a flood-threat recognition...

Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...

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...

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...

A 250 KW Closed Cycle Land Based Ocean Thermal Energy Plant
The paper describes the design of a 250 KW land based closed cycle Ocean Thermal Energy Plant suitable for installing at Keahole Point in Hawaii. The work is being done for ALCAN International....

Overview: Steam-Water Phase Change in OTEC Systems
This paper presents an overview of the thermodynamics and the heat and mass transfer processes occurring in OTEC systems utilizing seawater as the working fluid....

Seawater Experimental Results of Direct-Contact Condensation for OC-OTEC Applications
Tests of a direct-contact condenser (DCC) for open-cycle ocean thermal energy conversion systems (OC-OTEC) have been conducted using seawater and exchanging up to 1.25 MW_th...

Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...

De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...

Carbon Dioxide Release from OTEC Cycles
This paper presents the results of recent measurements of CO₂ release from an open-cycle ocean thermal energy conversion (OC-OTEC) experiment. Based...

Large Stone Hot Mix Asphalt: State of the Art
