Description
Summary:The paper analyzes changes in the hydro-physical properties of peat micro- and macrosystems in the process of drainage. Maximum moisture-holding capacity of peat is used as the main characteristic. With a full drying cycle and subsequent moistening of peat, there are three stages associated with the coagulative structure formation in the system. The boundary of the transition from the state «peat in water» to the state «water in peat» is moisture content equal to one. It divides the period of structure formation into two periods, due to the predominating action of van der Waals interactions or hydrogen bonds. In the state «water in pear» the peat system loses the ability to recover its original hydro-physical properties. Scaling up the research results on peat deposits (marshes) makes it possible to classify them according to the degree of drainage of the deposit. A new approach to the use of the term «surface water body» for peat deposits is proposed.
