GLOBAL GEOINFORMATION SYSTEM “SUSPENDED SEDIMENT YIELD IN THE RIVER BASINS OF THE EARTH”

Geomorphology RAS (2015)

Oleg Yermolaev Kirill Maltsev V. V. Mozzherin V. I. Mozzherin

General-theoretical and methodical problems of creation and use of the global geoinformation system, which reflects the basic regularity of formation, spatial and temporal variability of suspended sediment yield of the Earth's rivers, are considered. The role of river basins as geosystem formation in research of sediment yield is shown. Approaches to the automatic detection of river basin boundaries, methods of geoinformation system integration with thematic databases for purpose of geomorphological analysis of river suspended sediment yield are offered and tested.

TWO EROSION SYSTEMS IN THE RIVER BASINS OF THE EARTH'S PLAINS AND THEIR MUTUAL TRANSFORMATION (PART II)

Geomorphology RAS (2015)

A. P. Dedkov А. В. Гусаров V. V. Mozzherin

Functioning of the two main systems of erosion in the plain river basins, geomorphologic results of their activity and changes are not the characteristics of recent period only, but are typical for Pleistocene also. Alluvial deposits, formed during epochs of channel systems domination, fill the erosion hollows and have normal thickness, well-defined stratification at separate facies; slope deposits cover is cut off near valley flanges. Morphogenic and lithogenic processes were concentrated in the river valley bottoms, while slopes and watersheds represented to quite steady formations. Alluvial deposits formed during epochs of basin systems domination had wider distribution, increased thickness, and often were facially replaced by slope deposits near valley flanges. Relic landforms and surfaces of such epochs indicate intensive relief reorganization. Temporal changes of erosion systems have resulted in binary structure of river terraces in all valleys of the east (extra-glacial) part of the Russian Plain. The bottom alluvial series correspond to phases of predominant cutting (river channel system), top series correspond to predominant accumulation (basin system).

REGULARITIES OF THE FORMATION AND DISTRIBUTION OF QUATERNARY SEMIARID PEDIMENTS IN THE FOREIGN EUROPE (THE REVIEW)

Geomorphology RAS (2015)

V. V. Mozzherin

The review of the Russian and foreign literature made possible localizing the distribution of the relict planation surfaces in the foreign Europe. These surfaces are semiarid Quaternary pediments forming one of the youngest and lowest denudation levels. They are distributed over the Central and South Europe; northward they reach the boundary of maximum Pleistocene glaciation. Within this area, semiarid pediments occur discreetly, as more or less detached surfaces of flat gradient and different height. They are absent in the regions with maritime climate and in the axial zones of epigeosyncline mountains. The pediments formed under dry conditions during 600-800 millennia at the turn of the Eopleistocene and beginning of the Neopleistocene. The results obtained are in good correspondence with the earlier data for East Europe.

TWO EROSION SYSTEMS IN THE RIVER BASINS OF THE EARTH'S PLAINS AND THEIR MUTUAL TRANSFORMATION (PART I)

Geomorphology RAS (2015)

A. P. Dedkov А. В. Гусаров V. V. Mozzherin

The investigations of erosion in various landscape zones of the Earth's plains prove the existence of two basic systems of erosion: the channel and the basin ones. The principle distinctions of these systems show itself in structure of erosion processes and accumulation of their products, in hydrological regime of rivers, in character of dependence of specific suspended sediment yield on river basin area, in structure and thickness of alluvium, in relation between alluvium and slope sediments, in dynamics of river channels, in some features of river valleys morphology, in degree of preservation of relic landforms in the river basin, in general tendency of relief development (valley partition or planation), in intensity of sediment accumulation within the river channels and the flood-plains, ponds, and reservoir, etc. The present river channel system of erosion is divided into two subsystems: one of humid and semi-humid moderate latitudes and one of humid and semi-humid tropical and equatorial latitudes. The present basin system of erosion is also divided into two subsystems: anthropogenic one and natural (semi-desert, savanna, and sub-arctic zones) one.

GEOLOGICAL AND GEOMORPHOLOGICAL CONDITIONS OF OIL BITUMEN DEPOSITS PLACING AND BITUMEN OUTPOURING IN MIDDLE SHESHMA RIVER BASIN, TATARSTAN

Geomorphology RAS (2015)

V. V. Mozzherin

In the Volga-Ural bitumen zone, bitumen is concentrated in upper part of terrigenous sandstones of Sheshmian horizon of the Upper Ufimian substage. Sandstones form buried swell-like ridges up to 3-5 km long, 0.5-2.5 km wide, and 25-40 m height; to the top of them bitumen deposits are confined. For a long time these forms were considered as the bars of the end of the Early Permian epoch. New data (parallel orientation of these swells to contemporary river valleys, their location in the Middle Sheshma river basin, distinctive positions in swells, character of bitumen outpouring on the surface) bring us to accept their exotectonic origin. Owing to non-uniform static pressure, swells have been formed in strongly dissected relief at the turn of Miocene and Pliocene. Bitumen diluted high-porous sandstones, which were squeezed out from under watersheds in the direction of river valleys, where overlying rocks pressure was less. Similar subsurface folding in plastic rocks is widespread in the whole Middle Volga region. Distinct from those above geological and geomorphological conditions in neighbor areas restrict territorial distribution of bitumen deposits to Middle Sheshma river basin

Estimation of current denudation rate of the mountains based on the suspended sediment runoff of the rivers (the Tien Shan, the Pamir-Alai, the Caucasus, and the Alps as an example)

Geomorphology RAS (2015)

V. V. Mozzherin А. Г. Шарифуллин

Annual denudation rates were calculated using data on the suspended sediments runoff module of the rivers. These rates vary widely: from less than 0.005 to more than 1.75 mm/year in the Caucasus, Pamir-Alai and Alps; from 0.002 to 0.4 mm/year in the Tien Shan. The most significant factors of denudation cutting of the mountains are topography, climate and composition of rocks. The maximum rates of denudation (more than 1 mm/year) occur in the highest and most humid parts of the mountains (Western Alps, Western Caucasus, etc.). The minimum values of annual denudation rate (less than 0.1 mm/year) are observed on the lower mountain slopes with little rainfall and with resistant to denudation sediments (eastern slopes of the Lesser Caucasus, the interior of the Tien Shan, etc.). Vegetation and human activities can both enhance and suppress exogenous processes and thus the denudation rate. In all these mountains tectonic uplift prevails over the denudation.

DEVELOPMENT OF A HYDRO-STATISTICAL MODEL OF ESTABLISHING THE LIMITS OF STREAMS AND ITS VERIFICATION (ON THE EXAMPLE OF THE VYATKA-RIVER BASIN)

Bulletin of Udmurt University Series Biology Earth Sciences (2019)

A.R. Amirova Gulnara Kalimullina V. V. Mozzherin V.V. Khusnutdinova

A new unique method for establishing the shoreline of watercourses has been offered. In accordance with the Russian Water code, the border of rivers and streams is the shoreline with a long-term average annual water level for the ice-free period. That level is unknown in advance: it cannot be directly measured afield; it is not given in hydrological directories, as it is not considered to be characteristic, and on cartographic materials the outlines of water bodies are given at the average water level for the summer-autumn low flow period. To determine the desired level, the authors proposed a new method using the example of the Vyatka River. The method is based on a hydrolytic statistical model: the predicted parameter is the value of ΔH (the excess of the long-term average water level for the ice-free period over the average level of the summer-autumn low flow period), and the predictors (factors) of the model are the conditions of flow formation and passage. These factors are connected with ΔH by a power dependence, which has coefficients established by the least squares method from observations at 17 hydrological stations. The average calculation error ΔH was 5.4 ± 2.2 cm (significance level 0.05). The equation allows for any point or segment of the watercourse to calculate the desired level, and then establish a shoreline using large-scale maps. In this case, hydrometric observations are not needed. Mapping of the shoreline of the Vyatka River within the Kirov city and comparison of its position with the shoreline on a detailed space image received on a date close to the calculated level show that the standard error of the planned coastal position does not exceed 1.3 m, which meets the requirements to the accuracy of land boundaries of the water fund.
