Study of Diffusion Characteristics of Pollutant in Flowing Water

Abstract:

By considering the impact of the walls, water surface and river bed in straight and rectangular cross-section channel and analyzing concentration distribution of instantaneous point source, diffusion characteristics of pollutant were obtained that: (1) the vertical front position of pollutant, z_f, is proportional to 0.5 power of t; (2) the velocity of vertical front position, V_f, is inverse-proportion to the vertical front position, z_f; (3) the vertical front position, z_f, is proportional to the transverse front position, y_f.
