Once more on the «elementary morphological unit», its content and methods of its identification

Abstract

A precise wording is necessary to determine the «elementary morphological unit» (E. M. U.), so that everyone could establish it unambiguously. A simplest drainage area of a first order stream can be used as a unit of this kind. Such E. M. U. is the simplest cell of the hierarchic structure of the higher rank geomorphosystems.
