OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO. 90.12

SUBJECT:  PUBLICATIONS--Water-Resources Investigations Report
                        89-4061, "Proceedings of the Advanced
                        Seminar on One-Dimensional, Open-Channel
                        Flow and Transport Modeling"

Attached is a copy of the subject report by Raymond W. Schaffranek,
National Research Program.  The report is a compilation of short
papers that summarize oral presentations given at the National
Space Technology Laboratory (now the Stennis Space Center),
Bay St. Louis, Mississippi, on June 15-18, 1987.

The purposes of the seminar were to provide a forum for the
exchange of technical information among model users and
developers, as well as to identify immediate and future needs in
the areas of model development, enhancement, and documentation,
user support and training, and technology transfer to the
operational program.  Organized by National Research Program and
Office of Surface Water personnel, and supported by the Regional
Offices, the seminar presented a well-rounded program of topical
presentations of technical subjects in the field of open-channel
modeling and project summaries of water-resources investigations
being conducted by Water Resources Division (WRD) hydrologists.

This report should be beneficial for demonstrating to cooperators
WRD capabilities in the simulation of unsteady open-channel flow
and transport by one-dimensional mathematical/numerical models.
Included in the proceedings are project summaries for a number of
applications of the widely used branch-network (BRANCH) unsteady
flow model.  Applications of the single-reach (LTM) and branched
(BLTM) versions of the Lagrangian transport model and a case-study
demonstration of a debris flow model also are presented.  These
project summaries demonstrate model applications of varied levels
of technical difficulty and should serve to illustrate the wide
range of hydraulic investigations that can be approached by one-
dimensional simulation methods.

Topical presentations of technical subjects summarized in the
proceedings serve to demonstrate both the technical strength of
the mathematical methods developed within WRD and the depth of WRD
commitment to exacting analytical investigations.

The glossary of technical terminology in the appendix of the
report should be a valuable reference for report reviewers in the
field of computational hydraulics.

This report is being sent to Region, District, and Subdistrict
Offices of the WRD.  Copies for distribution to cooperators should
be obtained through standard report outlets.  A limited number of
additional copies for internal use can be obtained by contacting
the Chief, Office of Surface Water, or the Chief, Branch of
Regional Research, Northeastern Region.
