Abstract	In the flume experiment, the directions of measured velocity by 2D LDV (Laser Doppler Velocimetery) usually are not the streamwise and vertical direction of the flume respectively. And thus the measured velocity momentums are not along the streamwise and vertical direction of the flow. In this paper, the velocity momentums transfer considering flume slope with 2D LDV measurement is studied. Based on the defintions of velocity momentums, the transformation formulae are deduced. The application of the transformation formulae in uniform flow with rough bed shows that the slope can not be ignored.
