Updating Utah's Crop Water Use Estimates
Crop water use was estimated at National Weather Service stations throughout Utah for the 1961-1990 normal period. Daily weather data (air temperature, solar radiation, humidity, wind...
Effect of Choptank Watershed Drainage Project on Stream Temperatures
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A conducted a stream study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of channel construction...
A Model for Low-Drag Landslides
Field observations and experimental records indicate that the primary mode of motion of many large landslides is that of sliding rather than flowing. Most of the shear during sliding is...
Observations of Artificial Destratification
Artificial destratification using bubble plumes is one means whereby low dissolved oxygen in the hypolimnion of lakes and reservoirs may be averted. Temperature and DO were measured at...
An Assessment of Fish Entrainment and Impingement Potential for an Offshore Cooling Water Intake in a Tropical Bay
Fish entrainment and impingement potential were assessed for a proposed cogeneration facility on the west coast of Puerto Rico that will withdraw cooling water using offshore intake structures....
Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...
Quantity and Quality of Dry Weather Flow in Las Vegas Valley, Nevada
In recognition of the potential for dry weather flows to convey pollutants from the Las Vegas Valley, the potential economic and resource value of these flows within the Valley, and the...
Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal ? A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...
A Simple Finnish Method for the Structural Fire Design of Composite Structures
The structural fire design of composite structures in Finland has previously been based on furnace tests, which are expensive and take too much time to arrange. With the increasing prominence...
Seismic Performance and Composite Action of Older Structures
A study into the seismic performance of older steel structures is described. A review is made of the types of steel building construction completed during the period of interest, and the...
Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
Accuracy Requirements for GIS-Based Seismic Risk Assessments
Accurate assessments of potential earthquake damage and casualty risk are essential to the design of seismic hazard mitigation policies and seismically oriented engineering practice. More...
Considerations in Integrating Geographic Information System Technology in Earthquake Hazard Analyses
Seismic hazard and risk analysis can play a major role in identifying the potential consequences of an earthquake. Recent advances in computer based Geographic Information systems provide...
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....
Liquefaction Analysis in a GIS Environment
Liquefaction has been identified as one of the seismic hazards that brings great damage to property and infrastructure, and loss of life. The need for liquefaction analysis that works...
Liquefaction Potential of Western Puerto Rico
The historical seismic record, paleoseismic evidence, high population density, time expired since the last major earthquake, and the presence of liquefiable sands and soft clays combine...
Development of Geographical Information System (GIS) for Seismic Hazard Study of Charleston, SC
One of the most prominent areas of seismicity in the eastern U.S. is near Charleston, SC. The 1886 Charleston earthquake (M=7,5) and liquefaction evidence from at least five prehistoric...
CALTRANS Seismic Hazard/Risk Map and Proposed GIS Applications
The California Department of Transportation (CALTRANS) considers earthquake effects in planning, design, and construction of their structures. Obviously, CALTRANS has to respond to damaging...
A Prospect for Liquefaction Hazard Evaluation Using GIS
A brief description of a recently developed methodology to evaluate liquefaction hazard at a site is presented. In this method, uncertainty and scatter in the data are considered rigorously....
