Fluid meanders, such as river meandering, fluid intrusions, and microscopic flows over a surface, are difficult to model from classical dynamics. Another approach is to select trajectories from a randomly generated sample. This Demonstration generates individual trajectories with a few controls. The simulated process is a fluid bead sliding down a surface dominated by friction. There are occasional lateral displacements from a choice of distributions. For some choices of parameters, the courses, outlined by the extremes of the trajectory, look very much like meanders.
