Many-elements filtering of spatial frequencies normal stochastic fields for the first time is used, that enables to create sea bottom patterns, with any number of bottom layers containing different dimension and distribution heterogeneities (cavities and fillings), to vary the roughness of layers surface, to change mutual correlation of their form.
