Spatial conceptual models of slope development worked out by F. Ahnert

Abstract

The system modeling in the slopes' geomorphology developed by F. Ahnert is a synthesis of fundamentals of the geosystems paradigm, general principles of geo- and morphosystems (morpholithosystems) modeling and a system of models of exogenic and endogenic relief formation which is now in the process of development. On the basis of this approach F. Ahnert constructed a spatial model which presented the processes differentiation as a system of «process – response» type, which can include not only a single element of slope relief, but any drainage basin as a whole or any other area organized in a structural entity.
