Factor Model of the Geomorphological System of a Part of Northwestern Croatia

The method of factor analysis (R-mode) is applied as a tool in the system approach to the investigation of a selected geomorphological region in the Northwestem Croatia. The factor model derived from the analysis is a mathematical representation of the fourth-order d rain age basin system. It is composed of five orthogonal factors representing an assemblage of mutually uncorrelated subsystems as a framework within which geomorphic processes operate. Lithologic variables included in the analysis prove to be an inseparable part of the investigated geomorphological system. Loaded significantly on the specific factors, not only do they disclose the way the resistant geological framework opposes the activity of driving forces in the study area, but also indicate most straightforwardly the connection between the geologic structure and the area! extent of the certain rock types (lithology). The former is particularly evident in the case of the sl ope factor, while the latter is characteristic for the factor of vertical dis section.
