摘要
The development of methods for studying river runoff formation to integrate the up-to-day instruments of point hydrological–hydrochemical observations with new concepts and modern simulation means is discussed. The proposed methodological approaches are mostly based on the results of several years of works in an experimental mountain-forest basin in the southern Far East, Russian Federation. Despite the moderate experience analyzed in the article, the tested methodology is shown to be valuable and effectively applicable to basic hydrological studies and engineering–hydrological surveys, accompanying the designing of large facilities.
