EXECUTIVE SUMMARY
A devastating flood in Red River valley in 1997 emphasized the need to study the flood control measures in the Red River basin using state of the art modeling tools. The Red River and its floodplains can be modeled using one-dimensional, quasi two-dimensional or fully two-dimensional hydrodynamic models. Each modeling approach has its own advantages and limitations. The main purpose of this report is a comparison between one-dimensional (or quasi two dimensional) and fully two-dimensional hydrodynamic modeling approaches for modeling floods in the Red River basin.
A two-dimensional hydrodynamic model, MIKE 21, coupled with Geographic Information System (GIS) …
Metadata In A Digital Special Library: The Energy And Environmental Information Resources Center In Lafayette, Louisiana, Dan Foley
E-JASL 1999-2009 (Volumes 1-10)
This paper discusses three kinds of metadata and how they are used in the Energy & Environmental Information Resources Center (EE-IR Center), a digital special library of text, numeric, and geospatial data, located in Lafayette, Louisiana. These metadata are Dublin Core (DC), MARC21 (formerly USMARC), and Federal Geographic Data Committee (FGDC) metadata.
The EE-IR Center was formed as a partnership between the National Wetlands Research Center (NWRC) of the U.S. Geological Survey and the Center for Advanced Computer Studies of the University of Southwestern Louisiana (CACS/USL). Both partners are located in Lafayette, Louisiana. The EE-IR Center is funded by a …

A three-dimensional hydrodynamic-sedimentation computer model, HYSED-3D, was used to evaluate the effect of bridge-tunnel infrastructure for a proposed highway crossing of Hampton Roads on the physical characteristics (tides, currents, circulation, salinity, and sedimentation) of the James River estuary in Virginia. Model-represented infrastructure included tunnel islands and bridges on pilings connecting the islands to interstate highways in Newport News, Hampton, Norfolk, and Portsmouth, Virginia. Combinations of these elements occur in each of three proposed crossing routes designated Alternative 1 (Hampton-Norfolk), Alternative 2 (Hampton-Norfolk, Norfolk-Portsmouth), and Alternative 9 (Newport News-Portsmouth-Norfolk). Simulation comparisons were made between the existing waterways and infrastructure in Hampton …
