The U.S. Geological Survey, in cooperation with the Indiana Department of Transportation, has collected data at 5,587 bridges in Indiana built with federal aid. These data, which can be useful for assessing Streambed scour and channel instability, are maintained in a computerized data base at the U.S. Geological Survey in Indianapolis, Indiana. The data elements are grouped under one of five headings: General Site Characteristics, Observed and Calculated Scour Characteristics, Bridge Characteristics, Stream Characteristics, and Debris Characteristics. The description of the data in each group includes the element name; examples of the data from bridge number 89-54 crossing Lick Creek in Wayne County, Indiana; and a brief description of each element. The data already have been used in Indiana to produce an observed-scour index and a potential-scour index and may be useful in other applications as well. For computers with Internet access, the files containing the data for all 5,587 sites are available for downloading at the following URL:
