Abstract: The behavior of a nonbuoyant three-dimensional rectangular water jet with aspect ratios of 5, 10, and 20 were investigated based on experimental results of the mean velocity field obtained by particle image velocimetry. ...

Abstract: The complex nature of low‐flow mixing in natural channels has been investigated using both laboratory experiments and the numerical solution of a proposed mathematical model that is based on a set of mass balance equations ...

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 ...
