ABSTRACT
The concept of geofiltration or groundwater flow constitutes one of the fundamental characteristics of DGW. According to G. N. Kamenski, geofiltration flow refers to the spatial movement of groundwaters characterised by a specific form of linear flows and cross-sections. The system of mutually orthogonal lines of flow and head also constitutes the hydrodynamic network. The structure of a flow is graphically represented by the hydrodynamic network and is characterised by spatial position and direction of the vector of velocity of filtration, which is conducted towards standard points situated in the parts with diverse flow line shapes. The major tendencies in the dynamics of flow ought to be highlighted and analysed prior to the solution of truly hydrodynamic or ecological problems and creation of a network of observation wells with the sole aim of preventing pollution of groundwaters. One of the basic aspects of hydrodynamic analysis is the study of the form of structures.
