Abstract: Taylor's theory of diffusion by continuous movements and Einstein's equation of diffusion were applied to eddy diffusion of particles in two dimensional field of homogeneous turbulence in broad shallow channel with extreme bottom roughness; method of determining Lagrangian eddy size, eddy diffusivity, turbulence intensity, and mixing length; experimental verification of Kilmogoroff similarity principle.
