Cellular automata two-dimensional simulation of the suspension transfer
Based on the cellullar automation (CA-modelling), two-dimensional simulation model of transfer of the sediment inert suspended matter cloud is presented in terms of advective diffusion. Recently obtained empiric al relationships for calculation of the advective and diffusion components are used. CA loyalty allows to consider the main factors, influencing the transfer and suspended matter cloud sedimentation under conditions of rugged bottom relief of the shallow coastal waters. With the depth being constant, the CA model complies with the classical model of the advective diffusion. Examples of modelling in differe nt areas of the Kerch Strait reveal that the obtained results correspond in quality to the existing concept of advective diffusion in the shallow coastal waters. Implementation is conducted as a web program CA2DSIST (Cellular Automata 2D-Simulation Suspension Transfer) and is characterized by computation efficiency, which allows to timely preform simulation experiments with the suspended matter sources using slow computers. CA2DSIST is designated for operational calculations of the pollution parameters with the suspended matter emissions in order to assess negative effects on hydrobionts.
