Abstract
Measurements of the three Reynolds shear stresses in a fully developed flow in a mildly curved flume were executed using a 3-dimensional laser-Doppler velocimeter. An optical arrangement for turbulence measurements in shallow water flow in a flume was developed. For such flows equal eddy viscosity coefficients for the different Reynolds shear stresses are often assumed, which depend only on the main flow. However, this assumption appears not to be justified. It leads to an underestimation of the secondary flow intensity in a mildly curved flow.
