BRIDGE SCOUR DATA MANAGEMENT

A Bridge Scour Data Management System has been developed by the U.S. Geological Survey to support preparation, compilation, and analysis of bridge scour measurement data. Users may interactively store, retrieve, select, update, and display bridge scour and associated data. Interactive processing makes use of full-screen menus and form fill-ins, and an instruction window. Optional help and limits windows provide additional information for each of about 150 items in the data set for each bridge-scour site. The data set items include all of the essential information from a detailed scour measurement. Each data set has four categories of information: site data; measured scour data; flood event data; and channel geometry data. Program options permit selection of prediction equations and computation of scour depth estimates for comparison with observed scour depths. The program is written in Fortran 77 and is portable to personal computers, workstations, and minicomputers. The data base will facilitate: (1) developing improved estimators of scour for specific regions or conditions; (2) describing scour processes; and (3) reducing risk from scour at bridges
