Summary of BSDMS

       bsdms - Bridge Scour Data Management System

       The BSDMS has been developed to support preparation, compilation,
       and analysis of bridge-scour measurement data.  Users may
       interactively store, retrieve, update, and display bridge scour and
       associated data.  Help information provides descriptions of each of
       the more than 200 items that make up a data set for a bridge-scour
       site.  These variables allow local pier scour, local abutment scour,
       contraction scour, and long-term scour measurements to be described.
       The data set items cover all of the information for a given bridge:
       site data, measured data, flood event data, and channel geometry
       data.  Program options permit comparison of observed scour depths
       with estimates from selected published scour equations.

       Data entered through menus and form fill-in screens are saved in a
       binary Bridge Scour Data, or BSD, file.  These files are not
       compatible across different computer platforms but use of the
       "Archive" option allows data bases to be moved between platforms.

       The BSDMS was developed by the USGS National Scour Study in
       cooperation with the Federal Highway Administration. The beta
       version and version 1.0 were extensively tested by the USGS and
       subsequently modified to correct problems and make the program more
       user friendly.  Version 2.0 contains corrections to all problems
       identified in the previous versions, a verified computational
       module, and some enhancements requested by users.

       The BSDMS can be used to create new data-base files without the need
       of previously entered data.  More than 200 items for each bridge-
       scour site can be entered through a series of menus and form fill-in
       screens.  The 200 items include information on the study site,
       measured variables, flood characteristics, and channel geometry.
       The BSDMS may also be used to retrieve and view data from an
       existing "BSD" file previously created using the data base.

       The BSDMS can graphically display channel geometry, pier shape, and
       flood hydrographs on the screen.  No hard copy graphical output is
       currently available, but all data can be written to a labeled text
       file.  Data for one or more sites and all or a subset of the data
       can be written to the text file.  In addition, there is an "Archive"
       option to export the data to a specially-formatted text file that
       can then be used to create an identical binary "BSD" file on a
       different computer platform.

       BSDMS is written in Fortran 77 with the following extensions: use of
       include files, INTEGER*4 variables, REAL*8 variables, modifies
       FUNCTION arguments, equivalences mixed data types, and variable
       names longer than 6 characters. The WAIDE, GRAPH, AIDE, WDM, STATS,
       ADWDM, and UTIL libraries from LIB are required to recompile. For
       more information, see System Requirements from LIB.

       The USGS has used this program to store the data collected by
       various State cooperative projects that collected limited-detail
       bridge scour data.  The national bridge scour data base is
       distributed with version 2.0 of BSDMS.
