Summary To develop a method of safety assessments of river structures, it is fundamental to consider about local shear stress in terms of actual flow structures in river. Recently, we have used Acoustic Doppler Current Profiler (ADCP) in rivers during floods. This report is showing one of the results obtained from a radio-controlled boat with the ADCP.
