PORTABLE SCOUR MONITORING RESEARCH

Scour monitoring can be completed by either fixed or portable instruments. Fixed instruments are those that are installed and left at the bridge. During the last ten years, significant research and progress has been made with fixed instrumentation. However, fixed instrumentation is not suitable, practical, or cost effective for all bridges. In many cases portable monitoring may be a better solution, and yet, not much research has been completed to improve this type of technology. Recognizing this limitation, the National Cooperative Highway Research Program (NCHRP) funded project 21-07, "Development of Portable Scour Monitoring Equipment." The objective of this research was to improve deployment, positioning, and data collection procedures for portable scour monitoring work. These improvements will facilitate data collection under adverse conditions, and will allow more successful monitoring at a wide range of bridges under flood flow conditions. The research was conducted recognizing the need to provide solutions that are easily used and affordable by state and local bridge owners. The research concentrated on developing a truck mounted articulated crane to quickly and safely position various measurement devices. Collection of position and scour data is automated and a data file is written that allows plotting channel section or scour hole bathymetry.
