Scour in abutment of the bridge is one of the most important fields in river engineering, which has been extensively studied in the past six decades. Many bridges destroyed by abutment scour, despite many precise calculations that have done by engineers. Several investigations have done to determine depth of scour around bridge pillars in the laboratories. To calculate the depth of scouring understanding of the mechanisms governing on flow pattern and scour around abutments is needed. For this reason, many studies have been conducted about piles flow pattern, but there are few studies on the flow around the abutments. In this study the flow pattern around the abutments with semi-elliptical and trapezoidal rounded shape is investigated. The three-dimensional measurement of instantaneous speed at different levels horizontally and vertically using a tachometer (ADV) was performed. Profiles of velocity, shear stress, turbulence intensity and analysis of quadrant was performed to determine flow patterns. Studies on stress and velocity profiles around the abutments indicating the presence of both horseshoe vortex and downward flows in the upstream and in downstream of flow, presence of rising vortexes cause numerous irregularities. Also by quadrant analysis it was shown that in the semi-elliptical abutment near river bed ejection is most dominating event, and in trapezoidal rounded abutment both events have equal effect near the bed.
