Abstract: Field experiments on fluctuation velocities were carried out at the section Huanglingmiao of stem stream of Yangtze River with an Acoustic Doppler Current Profile (ADCP). And a number of data such as velocities of different discharges and different vertical lines were obtained. On the basis of Prandtls mixing length, the function relationship between mixing length and water depth was researched, which searched a feasible way on calculation of Reynolds stress and studied the closed Reynolds equations in the natural river. The paper also puts forward the quasi*.polynomial about calculation of mixing length on which the calculation of Reynolds stress is based. Finally, the calculated values are in good agreement with the field data.
