OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO. 87.05

Subject:  PUBLICATIONS--"Bridge Waterways Analysis:  Research
                        Report" by J. O. Shearman, W. H. Kirby,
                        V. R. Schneider, and H. N. Flippo, Report
                        No. FHWA/RD-86/108, 112 p.

The purpose of this memorandum is to distribute the subject
report.  The report describes the theory and methods used in a new
Water-Surface PROfile computation model (WSPRO).  The report also
presents the results of some limited model verification studies.

WSPRO was developed as a cooperative effort between the U.S.
Geological Survey (USGS) and the U.S. Federal Highway
Administration.  Existing step-backwater programs E431 and J635
should be phased out in favor of WSPRO.  WSPRO provides improved
computational procedures for flow through bridges.  It also
provides considerable flexibility for analysis of alternative
designs.  A "user-formatted" concept for the vast majority of the
input data makes the model considerably easier to use than
existing programs.

Some USGS offices are already using WSPRO, especially those
involved in Federal Emergency Management Agency projects.  User's
instructions for WSPRO are currently in "draft" form and probably
will be finalized in 6 to 8 months.

Additional copies of the subject report (the supply is somewhat
limited) and additional information regarding use of the model and
user's instructions can be obtained from the Office of Surface
Water.  The primary contact for WSPRO information is Jim Shearman.
Jim can be reached by telephone at FTS 959-5227 or (703) 648-5227
or via E-mail at JOSHEARMAN@RVARES.
