    Vertical deformations assessment of the small riverbeds in the northern Volga Upland (the Kud’ma river basin) was fulfilled. The rates of vertical deformations under the natural physical-geographical conditions are very slow. Karst processes play an important role: by controlling the water discharge they increase or decrease the influence of natural and anthropogenic factors on the deformations of the channels. The economic development of the Volga Upland led to significant anthropogenic transformation of the water and riverbed regime of small rivers. Dew to intensive anthropogenic load the rates of vertical deformations have increased dramatically. Classifi cation of vertical deformations of small river channels was compiled, taking into account the sign of deformation, dependence on the genesis, leading factors in the development. This classification became the basis for the zoning of the Kud’ma basin.

  • ВЕРШИННЫЙ ПОЯС ПЕРУАНСКИХ АНД И ПРОБЛЕМА АЛЬТИПЛАНАЦИИ

    УФИМЦЕВ Г.Ф. — 2013 г.

    The flattened surface Altiplano is dominant in the relief of the Peruvian Andes summit belt. The surface has stepped structure: wide and boggy pediments are embedded into high mountain steps. Volcanic processes, thermal and eolean weathering take part in the morphogenesis of Altiplano. The altiplanation process as overbasis planation surface development is fully presented in the Peruvian Andes. Its special discussion is needed within the frame of the mountain summit belt morphogenesis problem.

  • ВЗАИМОДЕЙСТВИЕ ЭНДОГЕННЫХ И ЭКЗОГЕННЫХ ПРОЦЕССОВ ПРИ РОСТЕ ЛОКАЛЬНЫХ МОРФОСТРУКТУР

    БРОНГУЛЕЕВ В.ВАД. — 2013 г.

    Cinematic model based on parabolic equation was used to demonstrate the interaction of endogenous and exogenous processes. Some characteristic morphological features of concurrently degrading and tectonically deforming slopes were described. Par example domed morphostructures pass into cone-like ones, monoclinal slopes are transferred into concave ones; maximal height of the morphostructure does not reach its value conditioned by tectonics. These effects manifestation is proportional to the ratio of exogenous/endogenous deformation rates. As the rise of block morphostructures is equivalent in certain respect to the lowering of denudation basis, these results are applicable to the development of erosion remnants and inselbergs.

  • ГЛЯЦИАЛЬНЫЙ РЕЛЬЕФ ЮГА КУЗНЕЦКОГО АЛАТАУ

    АДАМЕНКО М.М., АДАМЕНКО М.Ф., ГУТАК Я.М. — 2013 г.

    Glacial landforms are shown to be widely spread in Tigertysh mountain junction (Kuznetsk Alatau). There are about 132 cirques there. Their area varies from 0.2 km2 to 2.2 km2. They are usually located one above the other, forming 2-4 steps, widening to the top. Trough valleys are typical for northern slope of Tigertysh range and often end in ancient moraines. But in the valleys of the rivers Karatas and Nizhnaya Tayzhasy trough features may be traced lower than terminal moraine complexes. Four stage moraines of different age are found in the region. They are not covered by loess and thence were formed in the maximum of last glaciation or after it. During last glaciation epoch there were 56 glaciers with total area of 245.3 km2. The four stages of moraines and stepped shape of exaration landforms indicate longstanding and repeated glaciation of Kuznetsk Alatau.

  • ДЕФОРМАЦИИ РУСЕЛ ПОЛУГОРНЫХ РЕК В МЕСТАХ МОСТОВОГО СТРОИТЕЛЬСТВА (НА ПРИМЕРЕ РЕК ВОСТОЧНОЙ ХАНДЫГИ И АБАКАНА)

    РЕЗНИКОВ П.Н. — 2013 г.

    Changeable regime of semi-mountain rivers i.e. alternation of calm flow during low water and turbulent flood strongly complicates the forecasting of river bed deformations which characterized by intensive dynamics. Hazardous channel deformations near the bridge under construction over river East Handyga and near the rebuilding bridge over river Abakan are described. Errors in the forecasting channel deformations had been made earlier due to the use of the old standard methods which do not take into account the horizontal deformations of the channel.

  • ДИНАМИКА БЕРЕГОВ УНСКОЙ ГУБЫ (ЛЕТНИЙ БЕРЕГ БЕЛОГО МОРЯ)

    РЕПКИНА Т.Ю., САФЬЯНОВ Г.А. — 2013 г.

    Based on the results of fi eld work during 1987-2008 and analysis of satellite images, the primary role of the Coriolis force in the gulf’s coastal dynamics was established. The Coriolis force affects the tidal currents. As a result of the super-imposition of the tidal current over the north-east bearing constituent of an open sea wave disturbance, the west coast is marked by a positive sediment balance. The sediments here move towards the and of the gulf. The movement is accompanied by an intensive reshaping of the accumulation forms and coastal terraces (the wash-out occurs at the rate of up to 5m/year). At the eastern coast, the effect of the tidal fall and the storm waves reflected from the opposite coast, control the divergence of the sediment streams. This, together with land-slip processes at the coastal terraces and sharp deficit of sand material, results in the dominance of wash-out tendencies (up to 2m/year). Similar trends occurred during the Holocene.

  • ИНВЕРСИЯ СКЛАДЧАТОГО РЕЛЬЕФА КАК ПОКАЗАТЕЛЬ ТАНГЕНЦИАЛЬНОГО СЖАТИЯ ЗЕМНОЙ КОРЫ

    БУЛАНОВ С.А., ТРИХУНКОВ Я.И. — 2013 г.

    Folded morphostructures of various types are widespread in mountains. Inversion morphostructures (anticlinal valleys, synclinal ridges etc.) play an important role in mountain relief. They appear at different stages of orogens formation, but are more typical to mature relief and structures. Some examples of such ridges are given from two regions of Alpine-Himalaya mountain belt: the Northern Pamir and the West Caucasus. These ridges are represented by trough cores and have uppermost positions whereas the rocks, which build them up, are rather weak in comparison to those of neighbouring depressions. Authors explain the origin of such morphostructures by lateral compression of the folded massive: folding, elevation growth, and denudation go concurrently. Morphostructures of this kind may testify to large lateral compression of the Earths’ crust in corresponding regions.

  • КАРСТОВЫЕ СИСТЕМЫ: СВОЙСТВА, ИЕРАРХИЯ И ОРГАНИЗОВАННОСТЬ

    ТРОФИМОВА Е.В. — 2013 г.

    Concept of "karst system" is analyzed. The properties, hierarchy, and organization of karst systems are considered. It is marked that the organization of karst systems is manifested, on one hand, in the relation of the superficial and underground systems, and, on other hand, in its hierarchy; there are three main levels of the organization - global, regional and local.

  • ЛИТОЛОГОГЕОМОРФОЛОГИЧЕСКИЙ АНАЛИЗ КАК ОСНОВА КОМПЛЕКСНОГО ЭКОЛОГО-ПАЛЕОГЕОГРАФИЧЕСКОГО РАЙОНИРОВАНИЯ РУССКОЙ РАВНИНЫ

    АНТОНОВ С.И., ВВЕДЕНСКАЯ А.И., КОСТОМАХА В.А., НЕМЦОВА Г.М., СУДАКОВА Н.Г. — 2013 г.

    Complex investigation of the peculiarities of landscape formation and sedimentation is an important component of regional paleogeographic reconstructions. The geomorphological and lithologic maps compiled by the authors demonstrate the regularities of spatial differentiation and trends of age changeability of morpholitosystems. These trends served as the basis for mapping the paleogeographic zones of the East-European Plain with the history of regions' development taking into account. The separation of the territory into paleogeographic zones, provinces, regions was fulfilled with the following estimation of landforms stability. Paleogeographic approach based on the purposive zoning gives the possibility of complex assessment of natural environment stability and regions of ecological risk. Paleogeographic expertise improves reliability of forecast for the morpholithosystems development in extreme situations.

  • МАССОВЫЕ ДВИЖЕНИЯ ГРУНТА НА СКЛОНАХ И ИХ ВЛИЯНИЕ НА МОРФОГЕНЕЗ ЗАПАДНЫХ АНД (ЧИЛИ)

    НОВОА ХЕРЕС Х.Э. — 2013 г.

    Numerous examples of mass movements on slopes of western Andes and related landforms are analyzed. Regionalization of the country is fulfilled, taking into account climatic and hydrologic factors. 9 regions were distinguished with more or less similar physical-geographical conditions for mass movements development. Recommendations are suggested concerning future investigations in the field of mass movements risk under the rising anthropogenic impact.

  • МЕТОДИЧЕСКИЕ АСПЕКТЫ ПРОГНОЗИРОВАНИЯ РУСЛОВЫХ ПРОЦЕССОВ ПРИ ИЗМЕНЕНИИ ВОДНОСТИ РЕК

    ЛЬВОВСКАЯ Е.А., ЧАЛОВ Р.С. — 2013 г.

    The main methodical approaches of riverbed processes forecasting under increase/decrease of water content due to climate changes and human impact are analyzed. The authors estimate the workability of hydrologic-morphologic dependences. The relations of radii and wavelengths of meanders with water discharges are most elaborated, while such common correlations for braded channels are practically absent. The possibilities of the QI-diagrams use for the evaluation of the riverbed transformation due to changes of the factors affecting channel processes are shown. The main difficulties in further forecasting are formulated, in particular the lack of more or less reliable scenario of water content changes; the important aims are the validation of the most reasonable scenario, its application for channel processes forecasting for certain rivers, further estimation of hazardous consequences of channel processes.

  • МОДЕЛИРОВАНИЕ ДИНАМИКИ БЕРЕГА ИМЕРЕТИНСКОЙ НИЗМЕННОСТИ

    ЛЕОНТЬЕВ И.О. — 2013 г.

    It is shown that the coastline near the canyon Novyi is characterized by a rapid recession (about 7 m/y). Simultaneously the coast prominence at Cape Konstantinovskyi is truncated (4 m/y), and the eroded material is mainly transported into adjacent canyons. At the east ledges of the canyons Novyi and Konstantinivskyi the wave refraction leads to the energy concentration and the increase of longshore drift capacity. Because of intensive incision the drift of deposits will after sometime run out. In order to save the beaches a pebble material should be placed into eroded coast sections (90 and 50 m 3m —1y —1, respectively).

  • МОРФОСКУЛЬПТУРА ДОЛИНЫ Р. МАШЕЙ (ЦЕНТРАЛЬНЫЙ АЛТАЙ)

    БУЛАНОВ С.А. — 2013 г.

    Complexes of exogenous processes and morphosculptures in the mountain valley of the Mashey river (North Chuya Ridge, Central Altai) are described. 5 cites with different geomorphic structure were distinguished: two -in the river head occupied by glacier, two - in the high mountain part, where Pleistocene trough is transformed intensely by slope, cryogenic and fluvial processes, one - in the low mountain part, where the relics of glacial forms are predominant. On the base of paleo-trough and associate landforms morphometry the reconstruction of paleo-glacier Mashey was fulfilled. We ascertain that no Pleistocene moraines exist in the upper part of the valley, and that in Holocene a sharp change of geomorphologic situation took place, which led to accumulation renewal.

  • МОРФОСТРУКТУРА ПОЛИГЕНЕТИЧЕСКИХ РАВНИН: РАЗЛОМНАЯ ТЕКТОНИКА (НА ПРИМЕРЕ СИНАЙСКОЙ ПУСТЫНИ)

    ЧИЧАГОВ В.П. — 2013 г.

    The divergent cluster of faults – zone of large submeridional Pelusian arc, breaks Sinai microplate. Large sinistral displacement of this zone caused a set of geomorphic effects: formation of folded morphostructures of the Sinai microplate, development of morphostructures of the Red Sea rift, decay of the Thetis into two basins, northward movement of Africa, its Eastern drift from Mid-Atlantic ridge, and articulate latitudinal sheer of the latter. During Cenozoic and recent epochs arc-like fault morphostructures were formed. Being superimposed on Pelusian zone structures, they form complicated network of block morphostructures, which undergoes movements of different directions. A set of short low-amplitude seismic faults controls the southeast part of the Mediterranean seashore.
