Abstract

Geomorphology presents great complexity because of the numerous approaches to geomorphological analysis and the wide variety of geomorphological mapping scales. The nature of the geomorphic unit is controlled both by the chosen analysis model and the mapping scale required. The two main features fundamental for the basic geomorphic unit are homogeneity and indivisibility at the chosen scale. The basic geomorphic unit should have homogeneity, and may be defined in terms of genetic or structural pattern, which is the approach followed by the IGU (International Geographical Union) and most European geomorphologists. There is also an alternative used by British system followers, according to which the location and dimensions of geometric elements play an important part.
