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 7 Jul 1998 1 bsdms(1) U.S. Geological Survey (wrdapp) bsdms(1) 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.
