PRINCIPLES OF FORMATION OF STRUCTURAL GEOLOGICAL MODELS OF HETEROGENEOUS LAYERED BOTTOM

Abstract

The article describes the developed and implemented analytical and numerical methods for modeling layered geological structures with cavities of simple and complex shape. The developed author’s analytical and numerical methods of mathematical modeling of the structure and spatial distribution of acoustic properties of marine sediments, presented as a layered inhomogeneous medium, which allow to create discrete, continuous or mixed structural-acoustic models of inhomogeneous seabed taking into account stratification, the presence of cavities and inclusions of various shapes and properties. Models of geological layered environment implemented according to these algorithms are necessary for modeling panoramic survey (SSS), SSS with interferometric channel, multibeam sounder, three-dimensional profiling, construction of isobathic maps based on sounder measurements.
