NAME
bsdms - Bridge Scour Data Management System
ABSTRACT
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.
METHOD
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.
HISTORY
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.
DATA REQUIREMENTS
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.
OUTPUT OPTIONS
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.
SYSTEM REQUIREMENTS
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.
APPLICATIONS
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.
