Subcommittee on Hydrology


Second Federal Interagency Hydrologic Modeling

July 28 - August 1, 2002
Riviera Hotel, Las Vegas, Nevada

Abstracts due November 30, 2001

July 6, 2000

Theme: "Hydrologic Modeling for the 21st Century"

BACKGROUND: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. That highly successful workshop was limited to Federal participants. Subsequent to that Workshop, the SOH decided to hold a broader conference and to open it to all interested parties. The conference covered models addressing surface water quality and quantity issues and was held in 1998 in Las Vegas, Nevada. That conference, the First Federal Interagency Hydrologic Modeling Conference, was also very successful. One of the needs identified in that conference was for better coordination among similar model development/support activities in the profession. To address those needs and plan for the future, the SOH decided to hold this new conference, the Second Federal Interagency Hydrologic Modeling Conference, in 2002. In November 2000 a workshop was held in Tucson, Arizona to identify key issues and topics for the 2002 conference. The key issues and topics identified at the Tucson workshop are included below (see The 2002 Conference will follow a mixed set of formats including formal presentations, mini-workshops, and model demonstrations.

TOPICS: About 120 papers and 40 demonstrations incorporating results of recent research and technology development and/or applications will be solicited for presentation on the following subjects:

New observations and data for Hydrologic Modeling Uncertainty estimates for data, parameters and results
Instrumentation to support Hydrologic Modeling in the 21st Century Model Sensitivity Analysis and Error Estimates
Evaluation of Hydrologic Models by Regime and Climate Advances in Model Calibration Techniques
Standards for Hydrologic Data Remote Sensing/GIS Applications
Agency Specific Hydrologic Modeling Practices Data Sharing Information Management Automation
Research versus Operations Needs in Hydrologic Modeling Environmental River Management
Documenting Quality of Hydrologic Data Flood Hydrology
Establishing Standards for the Evaluation of Hydrologic Models Case Studies of Interagency Cooperation in Hydrologic Modeling
Error Propagation for Hydrologic Models Models Modeling of Major River Systems
Identifying Model Parameters Landscape Erosion, Sediment Transport
Sustaining River Environments Modeling Water Quality Transport Processes
Using Models in Developing TMDL's Modeling Dam Decommissioning

MODEL DEMONSTRATION: An evening session for up to 40 demonstrations will be offered. Individuals wishing to take part in these demonstrations will be required to furnish their own computers and software. In lieu of a formal paper, individuals wishing to participate in these demonstrations will be required to prepare an extended abstract for publication in the proceedings

WORKSHOPS: Several major topics will be chosen from the subjects listed above for the development of mini-workshops. Papers will be given on these subjects; a discussion and recommendation period will follow. These workshops will give participants the opportunity to influence and make recommendations concerning ways to close the gap currently recognized in model development and implementation.

WHO SHOULD ATTEND: Federal, State, and local agency personnel, consultants, academicians, and researchers involved in the development and/or implementation of surface water quantity and quality models. Also, individuals involved in decision making that depend upon data developed by these hydrologic based models. Individuals from outside of the United States are encouraged to present papers at the Conference.


Papers and computer demonstrations that address the theme of the conference and directly support the responsibilities and missions of the Federal Agencies will be given preference. Federal agency authors wishing to present papers and/or participate in the computer demonstration are requested to submit an abstract of not more than 500 words to their hydrology Subcommittee Representative (for SOH Reps. list see All other authors should submit their abstracts to Don Frevert or George Leavesley at the addresses below. Abstracts are due by November 30, 2001. Indicate which topic area the paper is to be considered for and whether it is to be an oral presentation or a computer demonstration or both. Authors are encouraged to submit their abstract via email. Authors will be notified of paper selection and provided with formal instructions by December 30, 2001. Final papers are due by March 30, 2002. Senior authors are responsible for obtaining approval of their papers by their organizations prior to final submission.
