The use of informational systems to estimate the required amount of chemicals for the dispersion of surface pollution is a fruitful approach in implementations of emergency response plans. A mathematical model of the processes of destruction of pollution on a water surface is an integral part in such a system and a source of accumulation of information about the evolution of pollution in various environmental conditions and characteristics of the source of pollution. Examples of the results of modeling the processes of surface pollution propagation when exposed to surface waves are presented, as well as a set of stored information for estimating the required amount of reagents.
