The work is devoted to the building of hydrodynamic models for the formation of anomalous pollution zones in surface water bodies. The aim of the study is to establish the physical mechanisms and conditions under which the formation of such zones is observed. The specific tasks are as follows: - significant weakening of the transverse mixing of water masses in surface water bodies; - sharp «explosive» increase in the intensity of the removal of pollutants from bottom sediments.
