A Statistical Climate Inversion Scheme and its Application in Hydrologic Impact Assessment Studies Associated with Global Climate Variability
The use of deterministic atmospheric, general circulation models (GCM's) to understand potential global climate change under doubled CO₂ forcing...

Field-Scale Research at the TVA Columbus Groundwater Research Test Site
TVA has been conducting large-scale field experiments at their Columbus Groundwater Research test site at Columbus Air Force Base since 1983. This work has been performed in cooperation...

Comparison of Nested Models' Local-Scale Precipitation from a Three-Year Base Run and a Corresponding Doubled CO₂ Run
Comparisons were made of nested model simulated precipitation from a 3-yr base run and the corresponding doubled-CO₂ run for the Gunnison watershed...

Nested Modeling of Watershed Precipitation
The U. S. Bureau of Reclamation's GCCRP (Global Climate Change Research Program) is concerned with the possible impacts of global change upon precipitation, environmental variables and...

Nonlinear Hydrodynamic Pressures on Dam Faces with Arbitrary Reservoir Shapes
A finite-difference method was used to calculate the nonlinear hydrodynamic pressures acting on the rigid dam faces during earthquakes. The geometry of the reservoir is in a realistic...

Hydraulic Analysis of the McCook Outlet Manifold
A 1:40-scale model of the proposed McCook Outlet Manifold was tested at the U.S. Army Engineer Waterways Experiment Station (WES). Subsequently, flow conditions in the manifold were calculated...

Limitations of Reduced Scale Testing on Parshall Flumes
A model for the boundary layer development in the entrance section of a Parshall flume is developed to account for the effects of fluid viscosity on flume calibration equations. Data for...

Model Study of Center Hill Fuse Plug Spillway
Model tests of a fuseplug spillway mounted on the fixed crest of an embankment dam were conducted to develop a satisfactory design that would fail in a orderly fashion at a prescribed...

Three-Dimensional Variable Resolution Hydrodynamic and Transport Modeling of the Chesapeake Bay System
This paper describes a domain decomposition methodology used in the application of the three-dimensional environmental fluid dynamics code, EFDC, to model hydrodynamics and transport in...

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...

Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...

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...

Connection of Beam Flange to Concrete-Filled Tubular Column
Research has been carried out on a frame composed of a concrete-filled steel tubular column and H-shaped steel beam with the aim of developing a reasonable connection method. The proposed...

The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...

Some Considerations for the Use of Geographic Information Systems
GIS have become widely used. Geotechnical earthquake engineers need both to understand what distinguishes a GIS form other data base systems and to make clear the purpose, use, and maintenance...

A Geotechnical/Earthquake Engineering Information System?Expanding the GIS Conceptual Framework
Data in a typical geotechnical and earthquake engineering study, encompass a variety of sources of information from site investigations, field instrumentation, dynamic computer simulations,...

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...

Earthquake Risk GIS Analysis for Ningxia Hui Autonomous Region, China
The Ningxia Hui Autonomous Region is a small autonomous region in the eastern part of northwest China and below Inner Mongolia with an area of 66,400 square meters. Ningxia's population...

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....
