First Federal Interagency Hydrologic Modeling Conference

April 19 - 23, 1998

Tropicana Hotel, Las Vegas, Nevada


"Bridging the Gap Between Technology and Implementation of Surface Water Quantity and Quality Models in the Next Century"


The Subcommittee on Hydrology (SOH), Interagency Advisory Committee on Water Data, held the Federal Interagency Workshop on Hydrologic Modeling Demands for the 90's in Fort Collins, Colorado in 1993. This highly successful workshop was limited to Federal participants. Subsequent to that Workshop, the SOH has decided to open this conference to all interested parties and to include models addressing surface-water quality and quantity issues. The Conference will follow a mixed set of formats including formal presentations, mini-workshops, and model demonstrations.

The Conference will provide a rare opportunity for professionals from State and local agencies, universities, international entities, and the private sector, as well as Federal agencies, to learn from each other and to network.


The Conference will be held at the Tropicana Hotel and Casino situated on the famous "Strip" in Las Vegas, Nevada. Las Vegas averages 310 days of sunshine per year and, besides being the "Entertainment Capital of the World," features family recreation possibilities such as Lake Mead, Hoover Dam, Red Rock Canyon, and Wet'n Wild amusement park. A considerable number of interesting places are within several hours of Las Vegas.


The Technical Program contains 133 papers and 31 demonstrations and (for pdf format) from the United States and 8 foreign countries, incorporating results of recent research and technology development and/or applications relating to surface water modeling on the following subjects:

Erosion & Sedimentation
    Bridge Scour & Channel Design
    Land Surface Erosion
    Sedimentation in the Yellow River Basin

River & Reservoir Systems
    Major River Systems

OPENING SESSION (Monday, April 20, 1998, 8:30 am - noon)

Welcome and opening statements will be made by the Conference Chair, Ming Tseng, and Robert Hirsch, Chief Hydrologist, USGS. Nancy Lopez, Chief of the Office of Water Data Coordination, will give a brief history of the Subcommittee on Hydrology and its modeling efforts over the Subcommittee›s 50+ year history. A panel of distinguished modelers, representing the Federal government, private consultants, large corporations, and the university sector will discuss the current state and future needs of hydrologic modeling.


A 7-hour session for 30+ demonstrations will be offered. A light dinner will be provided during the demonstrations.


Federal, State, and local agency personnel, consultants, and researchers involved in the development and/or implementation of surface-water quantity and quality models, as well as individuals involved in decision making that depend upon information developed by these hydrologic-based models should attend. Individuals from outside of the United States are encouraged to attend the Conference.
