Rock Creek?Cresta Sediment Management Plan
Pacific Gas and Electric Company (PG&E), an investor owned utility serving northern and central California, is working to manage sediments at its Rock Creek - Cresta Hydroelectric...
Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
Extended Experience with a Short-Term Hydropower Scheduling Model in New England
The New England Power Exchange (NEPEX) is responsible for the central dispatch of power throughout New England. To assure the maximum benefits of power pooling, the electric facilities...
Hydropower, Water Quality and Waste Discharge
Development of multiple hydroelectric projects on large river systems can result in potential reductions in dissolved oxygen (DO) concentrations. Municipalities along the Ohio River basin...
Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...
Prescriptive Model for Missouri River Reservoir-operation Analysis
The six main-stem reservoirs of the Missouri river system are operated by the Corps of Engineers for flood control, navigation, irrigation, power, water supply, water quality control,...
Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...
Infrared Thermographic Sensing of Sewer Pipeline Problems
When a sewer caves in, it often takes the street, sidewalks, and surrounding buildings along for the ride. These collapses endanger public health and safety. Repairing a sewer before such...
Principles of Infrared Thermography and Application for Assessment of the Deterioration of the Bridge Deck at the Zoo Interchange
This paper details the principles of infrared thermography from the underlying theoretical considerations to the physical constraints involved with performing the test. Infrared (IR) thermography...
Aerogel?A Transparent, Porous Superinsulator
Silica aerogel is an unusual, transparent, low density, thermally insulating solid useful for a variety of applications. We have been investigating silica aerogel for use in transparent...
The Desalination Situation
Rapid growth is putting increasing pressure on water supplies in coastal communities. Conservation can only do so much, and providing new freshwater supplies is getting more expensive...
Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...
Radiation Energy Treatment of Water, Wastewater and Sludge
A State-of-the-Art Report
Since ionizing radiation is one of the more technologically advanced forms of energy available to society, it has been applied to a great many activities such as: the sterilization of...

Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...
Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
Tying Back a Landslide
A slope covered with landslide debris is never the most desirable site on which to build, but sometimes it is the only one available. For the Forks of Butte hydroelectric power project,...
