| The knowledge about structure of the velocity in the stream is essential in the investigation of stream meandering, erosion and sediment transport, and dispersion of pollutants in the stream. In this study, theoretical velocity profile model in which transverse profile of the longitudinal velocity in the stream can be predicted using stream hydraulic data was developed. The proposed model was tested with the measured velocity data of the Nakdong river. The result shows that the numerical model simulates properly the general shape of the measured velocity profiles. The simulated profiles agree well with measurements, especially in the aspects of skewness and flatness. |
