The project examines the survivability and reliability of fixed-in-place continuous scour monitors for possible use in Indiana streams. The report considers primarily the experience with a sonar device at the US52 crossing of the Wabash River. Although very large flow events did not occur over the project period, the device has survived a number of smaller events, and has operated continuously without failure due to physical damage. Further, the data obtained, after appropriate processing, were examined for their credibility in terms of their correlation with a hydrologic parameter, the stage. A reasonably strong correlation was found, suggesting that the recorded data from the sonar monitor are a reliable indicator of scour (and fill). Recommendations are given regarding the applicability of the various different types of scour monitoring devices.
