C. -Pb. : RGSMU, 2008. — 178 s. ISBN 978-5-86813-202-5 . The monograph deals with the modeling of evolutionary hydrological processes. The main object of the study is a differentiable variety and a change in its dimension .. A watershed has been identified between the interclassical theory of catastrophes and partially infinite hydrology. Parallels are drawn between the paradigms of the C++ language and the algorithmization of epistemological transition processes based on the Darwinian triad: variability, heredity, selection. It is intended for specialists-hydrologists, students and persons interested in the methodology of science .
