Title

THE APPLICATION OF TWO-POINT METHOD FOR ESTIMATION OF FLOW HYDRODYNAMIC PARAMETERS IN MOUNTAINOUS COBBLE-BED RIVERS

Pages

  363-372

Abstract

 The study of mountainous rivers is recently considered by hydraulic researchers. Ten cross sections of a cobble-bed river, Behesht Abad, located in the central Iran were applied in this study. The distribution of velocity profile in cobble-bed and accuracy of two-point method to estimate the parameters of mean velocity and shear velocity were investigated and then the values of FLOW RESISTANCE were evaluated. Shear velocity was calculated by two-point method, and velocity profile and the results were compared by the parabolic and the BOUNDARY LAYER CHARACTERISTICS methods to predict FLOW RESISTANCE function. Results reveal that velocity profiles present S-shape and logarithm distributions. Also the values of mean velocity, shear velocity and FLOW RESISTANCE function calculated by two-point method can be presented with 94.6, 85.6 and 84 per cent accuracy, respectively. The results of this study can be extended to apply and to predict FLOW RESISTANCE for other mountainous rivers in Iran.
