Abstract:

A methodology of modeling organic matter degradation is described. It includes the identification of a class of disordered biopolymers embracing a considerable part of stable organic matter in the aquatic environment; the choice of a reference representative of the class, which is proposed to be lignin—a widespread product of wood degradation and processing; the construction of a three-level hierarchical scheme of degradation modeling, whose top level contains the formulation of the purpose of modeling, which is to find the law of the decrease in organic matter concentration over time, the middle level includes the development of a mathematical model, and the bottom level includes the analysis of the mechanisms of the processes. The general formulation of the problem at the hierarchical levels is developed from top to bottom, while the modeling process is realized from bottom to top.

Keywords: disordered biopolymers; lignin; aquatic environment; degradation; methodology; three-level hierarchical modeling
