Abstract : The principal purpose of this study was to evaluate and describe the performance and applicability of selected CSRP* (Continuous seismic reflection profiling) and sidescanning sonar systems to locate, identify, and monitor significant geological morphological, and man-made features or processes occurring in stream channels that are directly or indirectly involved in the process of streambank erosion. An additional objective of the study was to present types of equipment available and techniques of employing the equipment that can assist in various phases of engineering and geological studies located within fluvial environments. The major emphasis of this study was to determine the applicability of selected waterborne acoustic profiling systems at sites along streams where streambank erosion has been a recurrent problem. This report presents data obtained during waterborne surveys conducted on selected reaches of the Mississippi, Ohio, Missouri, and White Rivers. The data consists primarily of subsurface CSRP and side-scanning sonar profile records which provide graphic illustations of the capabilities of these systems to detect and monitor riverline features and processes.
