Designing Self-Cleaning Wet Wells for Wastewater Pumping
Guidelines for the design of self-cleaning wet wells for variable speed pumps are given. The progress of research on the design of wet wells for constant speed pumps, including submersible...
San Francisco Bay and Delta Oil Spill Fate Studies Part I: Hydrodynamic Simulation
A two-dimensional vertically-averaged finite element model was used to simulate the hydrodynamics in San Francisco Bay and Delta to support oil spill fate studies. Simulations were performed...
San Francisco Bay and Delta Oil Spill Fate Studies Part II: Oil Spill Simulation
Because of the presence of oil refineries and significant tanker and barge traffic in the bay and delta region, the possibility of a moderate or major spill in the area must be considered....
Extreme Events and Coastal Wetlands
Temporal ecosystem behavior in tidal wetlands can be static, dynamically stable, progressively changing, or subject to catastrophic change during extreme events. Catastrophic change in...
Predicting Water Quality at Municipal Water Intakes Part 2: Application to the Southern Sacramento-San Joaquin Delta
Work in progress on developing methodologies for predicting water quality at Municipal intakes in the Sacramento-San Joaquin Delta is discussed. Principal sources of salinity are identified...
Sediment Disposal and Transport in Central SF Bay
The relocation of dredged material from navigation channels in the Francisco Bay is crucial to the movement of deep-draft shipping and shallow-draft recreational vessels. The margins of...
Interpreting Debris-Flow Hazard from Study of Fan Morphology
The deposits, stratigraphy, and surface morphology of debris-flow fans are a record of past debris-flow activity, and as such can provide useful information about debris-flow hazards....
Survival of Atlantic Salmon Smolts Bypassed Through Ice-Log Sluices Determined by the HI-Z Turb'N Tag
The HI-Z Turb'N Tag was used to assess injury and mortality incurred by Atlantic Salmon (Salmo salar) smolts bypassed through ice-log sluiceways at two stations. Both sluiceways were similar...
Gully Intrusion on Reclaimed Disposal Sites
A three-phase gully erosion study was initiated at the Engineering Research Center of Colorado State University, in cooperation with the U.S. Nuclear Regulatory Commission. The objective...
Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...
Modeling the Tides of Massachusetts and Cape Cod Bays
A time-dependent, three-dimensional numerical modeling study of the tides of Massachusetts and Cape Code Bays, motivated by construction of a new sewage treatment plant and ocean outfall...
Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...
GIS for Regional Seismic Hazard and Risk Analyses
Earthquake occurrences cannot be accurately predicted or prevented, but their damaging effects can be analyzed and possibly reduced by utilizing the available geologic and geographic information....
Assessment and Repair of Fire-Damaged Concrete Structures
Concrete, even though it may be the most fire-resistant of all the major building materials, can be damaged by fire. Seldom does even a major fire cause total destruction, however, most...
Present and Future Use of Coal Ash in Construction and Related Applications
The American Coal Ash Association, Inc. (ACAA) is an organization of producers and marketers of coal combustion by-products. An annual survey of coal-burning electric utilities is conducted...
Ground Penetrating Radar: Images of Subsurface Characteristics
Ground penetrating radar has not been widely used for subsurface exploration in Civil Engineering. This paper describes the experimental setup used to explore ground penetrating radar...
Non-Destructive Remote Sensing of Hazardous Waste Sites
This paper describes how the non-contact, nondestructive, remote sensing techniques, of Computer Enhanced Infrared Thermography and Ground Penetrating Radar, may be used to detect buried...
Fly Ash for use in the Stabilization of Industrials Wastes
Fly ash and other coal combustion by-products are used in the stabilization of industrial wastes. This paper describes the various types of fly ashes, the mechanisms of strength development,...
Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....
