Strategy of protection against hazardous channel and hydrological processes in rivers of developed territories and territories with focal development
In 2012-2015, the Makkaveev Research Laboratory of Soil Erosion and Fluvial Processes of MSU, Department of Geography, carried out a research, including analysis of hydrological and channel regimes of the Tom river in the Kuznetsk basin (Kuzbass) and the Katun river up to Uimonsky (the Altai), intra-mountain drainage basins, the survey of floodplains and eroded banks, and modelling of floods occurring in floodplains. As a result, a concept has been developed to improve protection measures against hazardous hydrological and channel processes. More than 200 engineering and organisational events were suggested as part of the concept. Given the dense network of river banks and the high potential damage caused by floods in Kuzbass, the continuous protection of cities, large residential and commercial areas, as well as sections of roads and railways subject to erosion is a priority in the flood control concept. In the case of the Katun river basin, characterized by local development, low population density, and relatively small damage caused by floods, the emphasis is put on organisational measures: prevention, evacuation of people and property, insurance and compensation. Selective engineering structures should, as a matter of priority, reduce the dangerous erosion of river banks and ensure a high level of protection of the territory against floods
Structure and peculiarities of the (8 x n)-type Si(001) surface prepared in a molecular-beam epitaxy chamber: a scanning tunneling microscopy study
A clean Si(001) surface thermally purified in an ultrahigh vacuum
molecular-beam epitaxy chamber has been investigated by means of scanning
tunneling microscopy. The morphological peculiarities of the Si(001) surface
have been explored in detail. The classification of the surface structure
elements has been carried out, the dimensions of the elements have been
measured, and the relative heights of the surface relief have been determined.
A reconstruction of the Si(001) surface prepared in the molecular-beam epitaxy
chamber has been found to be (8 x n). A model of the Si(001)-(8 x n) surface
structure is proposed.Comment: 4 pages, 8 figures. Complete versio
