Optimal Real-Time Operation of a Cascade of Hydropower Plants in Central West China
The Longxihe River hydropower system consists of four hydropower plants in series. The four reservoirs are used for flood control and power generation. Among the four reservoirs, only...
Artificially Varied Flow: River System Management
Some of the major water quality problems are heat, color, organic sediment, and total dissolved solids. To dilute these and other pollutants, substantial augmentation of flows for water...
Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...
Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...
Temperature Effects on Lasers
While lasers have markedly improved the accuracy of engineering, air temperature gradients can reduce that drastically. Based on a sewer project that used lasers to align all the pipe,...
Measurement of Ice Forces on Structures
Methodologies and techniques are discussed for measuring ice forces on fixed structures situated in rivers and lakes. The usual method of measuring ice forces is to place a load frame...
Water Pollution Control Plant Upgraded to Meet EPA Regs
An Outstanding Civil Engineering Achievement Award Nominee, Philadelphia's Southwest Water Pollution Control Plant, has a $300 million addition which nearly doubled plant...
Dike Safety Upgraded with Millions of Square Feet of Fabric
Nonwoven fabrics of two different weights were used in an $80 million dike reconstruction project in southern Florida. Florida Power & Light Company rebuilt the embankment to a...
A Guide for the Field Testing of Bridges
The history and present use of bridge testing are reviewed. The benefits of bridge testing include safety and reliability, the money saved by not constructing a new bridge, the improvement...
Solar Energy for Heating Homes: How Practical�
There is a widespread belief that on-site solar energy for heating homes is still not a proven technology and that, in any event, it's much too expensive. The fact is that...
How about Reverse Filters
Reverse or inverted filters allow water to drain freely without carrying away suspended solids. Their pore size must be properly related to the fines being protected. Terzaghi's...
The Zero-Energy House: The Bold Low-Cost Breakthrough that may Revolutionize Housing
The world is in the early stages of a revolution in housing. About 200 houses have already been built in Canada that use under $125/yr for electric-resistance space heating�� even where...
Electricity from the Sea
In Hawaii, the state, Lockheed Space and Missile Co. and Dillingham Corp. have conceived, designed and built the first prototype ocean thermal energy conversion plant. OTEC uses the 40�F...
Acid Rain
Current information on acid rain is reviewed in eight papers presented at an April, 1979 session sponsored by the Research Council on Environmental Impact Analysis of the ASCE Technical...
Proceedings Volume I
Polyphase Flow Transients Pressure Recovery Devices Intake Structures Cooling Water Systems
The papers presented in these proceedings represent a variety of disciplines from many countries. This unique jointing of three major societies has created a collection of papers with...
Doing Business in Saudi Arabia
The consulting firm or contractor eager to get a piece of the action in Saudi Arabia must be prepared to endure some hardships. Foreigners can't own land but can rent living...
Don't Look Up, Look Down
In response to the rising cost of energy, the designers of the Terraset Elementary School, Reston, Va., buried it under 2-3 ft of earth. The resulting high thermal mass allows the building...
Inflatable Dam Regulates River Level
Inflatable dams are economically feasible for maintaining a required constant water elevation on rivers and streams where flooding poses problems. Puncture resistant material, inflated...
Stress Ribbon Bridge in Freiburg, Germany
A three span continuous stress ribbon bridge of 75, 130, and 138 ft, was built in downtown Freiburg, W. Germany, for pedestrian traffic. Structural analysis is similar to that of suspension...
