Transport of Contaminants Through the Bottom Sediment Layer. 2. Analysis and Applications
摘要
The paper suggests a thorough analysis of regularities in the transport and accumulation of contaminants in a bottom sediment layer, and in the discharge of those into subgrade soil for a wide range of variation of modeling parameters. Two characteristic subphases are recognized in each of two phases of the process. A background is given for conditions that define a contaminant localization in the bottom sediments. Limits are found out within which the kinetics of exchange processes affects the propagation of the contaminants by increasing their mobility in the first phase and suppressing it in the second one. Estimates are given for the time of characteristic redistribution of the contaminants in the sediment layer, and for an initial moment of their essential discharge.
