Abstract: In this study, a theoretical formula for a one-dimensional longitudinal dispersion coefficient was developed using the lateral distribution equation for depth-averaged streamwise velocity derived from the Shiono and Knight ...

Abstract: In this study, a theoretical method for predicting the longitudinal dispersion coefficient is developed based on the transverse velocity distribution in natural streams. Equations of the transverse velocity profile for ...

Abstract: A new theoretical equation is proposed to describe the streamwise variations of the transverse velocity along a curved channel with a constant curvature. Furthermore, based on this theoretical equation for the transverse ...

Abstract: Two types of dispersion coefficient tensor for meandering channels were examined. The first type was estimated using measured vertical velocity profile in an S-curved channel, and the second type was based on the depth-averaged ...

Abstract: Mixing characteristics of conservative pollutants were examined two-dimensionally in a laboratory meandering channel, and a method to compute the dispersion coefficients was developed based on the measured concentration ...
