PECULIARITIES OF HEAVY METALS MIGRATION AND ACCUMULATION IN THE ENVIRONMENT OF THE LAKE KULTUBAN (THE SOUTHERN URAL)

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

Coupled analysis of Cu, Zn, Fe, Ni, Pb, Mn, Co, Ba, Sc, Ti , Cd in water, bottom sediments and soils on the watershed of the Kultuban lake (Southern Urals) was performed. Main factors of metals lateral differentiation in catena were identified. Differentiation of litophile and siderophile (Fe, Ni, Mn, Co, Ba, Sc, Ti) elements are caused by natural factors related to bedrock chemical composition in autonomous and transeluvial facies. Accumulation of Cu, Zn and Cd noted in accumulative landscapes is caused by aerial input of aerosol produced by mining facilities located in the city of Sibai 6-10 km from the lake.

FORECASTING OF DEFORMATIONS OF BUILDING STRUCTURES ACCORDING TO THE RESULTS OF GEODETIC OBSERVATIONS

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

The practical results of geodetic measurements allow not only to determine deformation of structures and engineering structures, but also to predict the process of deformation. Forecasting of deformations of buildings and its parts are manufactured on the basis of information which is obtained by various methods. Processing of such data is carried out by methods of mathematical statistics with the involvement of the probability theory. This publication provides the most common used methods of forecasting of deformations of building structures according to the results of geodetic observations.

COORDINATE THE METHOD OF DETERMINING THE RADII OF CURVES ON THE ROADS

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

The article describes the method of determining the radii of curves during the construction and certification of roads with the use of global navigation satellite systems (GNSS). The formulas to determine the average square error of determining the radii of horizontal and vertical curves on the roads and the estimation accuracy. On the basis of the obtained results proved the production efficiency of the developed method. The technology of geodetic control can be carried out in modes of post processing of satellite measurements and RTK, and also allows you to determine the length of the curve

IDENTIFICATION OF FLOOD-PRONE AREAS USING DIGITAL TOPOGRAPHIC BASE

Posted in 2017, Issue № 1(55) January 2017, SCIENCES ABOUT THE EARTH | 0 comments

The article deals with the current state of the problem in estimation flooded areas caused by inundations, river floods and hydrodynamic accidents. As a result of normative literature studies issues that are not represented have been presented. To develop new method suggested using the influence type of surface topography and out-of-parallel of initial levels. The solution of these states will allow to predict flooded areas and to identify areas favorable for the application of protective measures.

OPERATIVE UNDERGROUND HELIUM-RICH GAS STORAGE

Posted in 2017, Issue № 1(55) January 2017, SCIENCES ABOUT THE EARTH | 0 comments

One important issue with the unique helium-rich gas deposits development in Eastern Siberia and the Far East is helium recovery and storage. Helium is a non-renewable resource. Compared with natural gas, helium has much lower density and higher viscosity as well as extremely high penetrability. These properties determine the features of helium behavior in a porous reservoir after injection. In particular, high penetrating power leads to high requirements for cap rock quality. The article provides recommendations on creation of operative underground helium-rich gas storages in undeveloped natural gas fields as well as analysis of helium behavior after injection into a natural gas reservoir depending on the reservoir properties (porosity and permeability).

FORECAST OF LEEWAY’S TRAJECTORIES OF FREE-DRIFTING OBLECTS ON THE SURFACE OF THE OKHOTSK SEA

Posted in 2017, Issue № 1(55) January 2017, SCIENCES ABOUT THE EARTH | 0 comments

There are represented model and real experiments of leeway of drifting objects, attached to the surface of the sea pollution problems. Those experiments were held with drifting buoys in the central part of water area of the Okhotsk Sea. Here are results of research of separated influence of wind and termohaline component on the leeway. Model estimates showed, that wind field only is insufficient for the forecast. It is necessary to take into account also the termohaline component of the surface current of the sea. Data of the satellite’s altimetry is offered for use. There are represented real trajectories of object’s leeway, model trajectories, using wind data and model trajectories, using termohaline currents. It was noticed, that atmospheric synoptic cyclones lead to unpredictable stochastic movements of objects and difficult to forecast the object’s leeway
