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.
Ecological and Applied Geomorphology
In the years 1976-1993 the disciples S.S. Voskresensky according to his ideas made a detailed reconstruction of river valleys evolution history for Western Priokhotje, Lower Amur region and Amur-Zeya plain. It was established that in each climatic epoch, these areas had comprised one landscape type with poor vegetation cover differentiation. The correlation of accumulation and incision stages in valleys with climate continentalization and humidization was found. The stages of river valleys formation during Plio-Pleistocene, including alternation of accumulation and incision, are generally synchronous within the studied region. Processing of transitional Plio-Pleistocene gold-bearing reservoirs produced the most favorable conditions of placers formation. Such conditions existed at the places of inherited river valley development in the mountains and at the places of sugarloaf and caldron topography with minimal value (< 30 m) of erosional downcutting on the plains.

The model of the Ostashkov ice sheet degradation was created оn the basis of geomorphologic and GIS analyses. The model was made for Chudsko-Pskovskaya lowland, for the Luga (Haanja) – Neva (Pandivere) stages. Frontal type of deglaciation was proved for lowland properly and the areal type – for surrounding uplands. Numerous evidences of specific glaciomorphologic complexes of marginal formations helped analyzing ice sheet dynamics. The absolute ages were calculated for Pskov (15000 – 15100 BP) and Remda phases (14400 – 14300 BP), both belonging to the Luga stage. Based on spatial analysis of coastal landforms within the Russian Federation, proglacial lake levels were determined. For the Pskov stage it was made for the first time.
Tension (or intensity) of geomorphological system is its inclination to be in the state of instability, out of balance. It corresponds to high probability of catastrophic processes realization. The intensity of geomorphic processes in the Andes is determined by tectonic activity, volcanism, deeply dissected topography, high precipitation, seismicity, significant human impact. Most extensive geomorphologic disasters of the region are usually due to the superposition and interaction of the number of extreme processes.
Of 4100 names in the 5 largest cities of Chernozem’e (Voronezh, Lipetsk, Kursk, Belgorod, Tambov) related to landforms (morphogodonims) the maximum number is in Kursk (3.8% of total street number), the minimum number – in Belgorod (0.9%), though the territory of the latter has the most complex morphology. It indicates an absence of correlation between relief complexity and morphogodonims frequency in the cities which differ historically and administratively. Morphogodonims are situated by the most part in the places with prominent relief. In the large towns of Chernozem’e there is a tendency for the morphogodonims to disappear: the new streets aren’t named by relief features and old names are frequently changed to new ones not related to land surface morphology.
History of Science
V.A. Obruchev studied relief of deserts and eolian relief forming under new tectonics development. Up to him new tectonics corresponded with those earth crust structures which formed under very young movements took place in the end of Tertiary and first part of Quaternary period. Last researches in various countries found out that these movements greatly spread and play significant role in present-day relief forming. In his opinion, separating them from Alpine tectogenesis cycle is necessary because in some cases they appear more or less hard in those Earth’s regions where structures were formed by more early cycles – Hercynian or even Caledonian, and Alpine cycle were absent or poor.
Reviews
The role of river mouth is great. As a rule, most important transport junctions are situated here – ports; many valuable fish breeds are pass the mouth on their way to spawning; river sediments receive to coast zone and compose beaches on sea-side places, etc. Deltas – are natural storages of organic natural fossils such as oil, coal, gas. Not so much scientists know details of complicated natural processes in river mouths as Vladislav N. Korotayev does. In his monograph “Geomorphological sketches of the mouth and coastal systems” he summarized results of his longstanding studies.

8–12 of October 2012, Izhevsk, Udmurt State University hosted next annual Plenary Conference of Interuniversity Scientific-Coordination Council for Moscow State University on erosion, channel and mouth processes issues. This Conference was spend within the framework of All-Russian Scientific-Applied Conference with international participation “Issues of applied and regional geography” devoted to 50th anniversary of geographical education in Udmurt Republic and 55th anniversary of Udmurt Republic branch of RGS. It was fourth alike Conference in Izhevsk; all organizational severities lied on Geographical Department of Udmurt State University. In parallel with working of XXVII Plenary Conference also some sections worked: “Research of channel facilities of territory”, “Regional and applied geoecology”, “GIS in regional research”, “Regional aspects of biogeography” and “Problems of geographical educations”.
25-29 of September 2012, Belgorod Research Scientific State University hosted All-Russian Conference – XXXII Plenary meeting of Geomorphological Commission RAS on geomorphological-anthropogenic problems. This was the second Plenary meeting prepared and organized by Geomorphological Commission with active participation of A.N. Petin – Head of Department of Geology and Geography in Belgorod University, and lecturers P.V. Goleusov and S.N. Kolmykov. Here in 2000 XXV Plenary meeting of Commission was organized on problems of environmental geomorphology.
