Abstract: Measurements of velocity around the solid body in the flow is very important in hydraulics. But, it is very difficult to measure velocity exactly, because the vertical profile of velocity behind the solid body so complex that there are almost no or backward components in the main flow direction. However, in recent year we can measure the small components of flow by using LDV (Laser-Doppler-V elocimeter). So we set up the trapezoid weir model in the open channel with the smooth bottom and measured velocity around the weir model by using LDV. Then, we calculated the turbulent properties from measured data.
