The relevance of the research is determined by the necessity to study paleohydrological conditions, which play an important role in formation of geochemical anomalies. The methodology of such studies is currently not sufficiently developed, that affects the reasonableness and effectiveness of searches of minerals. The aim of the research is to develop and substantiate the methods of paleohydrological reconstructions for determining the total runoff caused by the zonal climate. Methods: geographical and hydrological and statistical methods, mathematical modeling of hydrological processes. Results and conclusions. The authors have developed the mathematical model of formation of total zonal runoff. On its basis the methodology of paleohydrological reconstructions was proposed and tested. By means of the model the authors determined the non-synchronous change in the zonal water runoff in northern and central parts of Western Siberia, caused by different trends of climatic changes and geo-ecological conditions. It was shown that more abrupt and differently directed water runoff fluctuations during the Holocene are more typical for northern regions, currently corresponding to the northern taiga subzone, forest tundra and tundra zones. The changes of water runoff are less pronounced and more closely associated with wetland processes in the subzone of the southern and middle taiga. The authors made the conclusions that the increase in the water runoff variability as a whole would lead to a certain growth in the variability of the contents of a number of dissolved substances and consequently the probability of formation of hydrogeochemical anomalies. In the medium term the increase in forested catchments should be expected with continued warming. At the same time the increase in total water runoff is probable in areas with less than 40 % swamping.
