Roll Waves in Mud Flow
Permanent roll waves on a shallow layer of fluid mud which is modeled as a power-law fluid is studied. Based on long-wave approximation, momentum integral method is applied to derive the...
Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...
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...
Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...
Large-Scale Embankment Overtopping Protection Tests
The U.S. Bureau of Reclamation (Reclamation), Colorado State University (CSU), and the Electric Power Research Institute (EPRI) have an ongoing cooperative research effort to determine...
Progressive Failure of an Overtopped Embankment
The failure of an overtopped embankment is a problem of a very complicated nature. Concerned organizations are interested in information that can be used in future planning and development...
Oxygenation Experiments in the Wave Breaking Zone
Experiments on oxygenation due to waves breaking on a uniformly sloping beach were carried out at the laboratory of Harbor Works, National Technical University of Athens. The influence...
A Finite-Difference Model for 3-D Flow in Bays and Estuaries
This paper describes a semi-implicit finite-difference model for the numerical solution of three-dimensional flow in bays and estuaries. The model treats the gravity wave and vertical...
The Courant Number and Unsteady Flow Computation
The Courant number C, the key to unsteady flow computation, is a ratio of physical wave velocity, ?, to computational signal-transmission velocity, ?, i.e., C = ?/?. In this way, it uniquely...
Three-Dimensional Modeling of Tides and Wind-Waves
A third-generation coupled discrete numerical wave prediction model is dynamically linked to a three-dimensional hydrodynamic model. The effects of water level, currents, and bottom friction...
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...
Proposal on Story Drift Limit Based on Axial Behavior of Column under Seismic Loads
The main function of columns primarily is to support axial loads both under and after repeated lateral loading from earthquakes. A definition of the story drift limit in any structural...
Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
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....
Geographic Information System Planning for Geotechnical and Earthquake Engineering Applications at the Savannah River Site, SC
The Savannah River Technology Center (SRTC) of the Savannah River Site is in the planning stages of compiling a geological, geophysical, and seismological data base on an industry standard...
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...
