Abstract
In this textbook the author tries to integrate the investigation of processes which create small scale landforms and the new developments of investigations on a global scale. These are especially plate tectonics, sealevel change, and climatic changes. There are 5 parts: In an introduction the fundamental concepts as they have been developed in the English speaking world in the last two decades are discussed. Part 2 covers the endogenic processes, the plate tectonics, and igneous activity. Associated landforms are more or less the structural forms, why and where there might be divergences from tectonic lines is not particularly discussed. In part 3 a rather conventional description of exogenic processes and landforms starts with weathering, covers slope processes and forms, fluvial, eolian, glacial, periglacial, and coastal processes and landforms. But in comparison to what is called in German “climatic geomorphology” - probably this should be named in a better way “dynamic geomorphology” - there is a fundamental difference. It is not only the single process or landform which should be analysed, but the combination of processes and thus the set of landforms. In “dynamic geomorphology” there is a qualitative appraisal of the processes. Only in this way the explanation of the landscape or the landforms is possible. Besides this gives a good basis for measurements and especially extrapolation of measurements is not possible without an analysis of the process combinations. Furthermore there is a close feedback to climato-genetic geomorphology. One can proceed with the latter from single landforms typical for a paleoclimate, but the whole analysis of the set of landforms is only possible with the estimation of the process combinations of the recent and paleoclimates.
