The article reveals the characteristics of the main urban zones: central, middle, peripheral. The place and the role of industrial areas in the structure of the major planning zones of the city are examined. The priority areas for change and a new functional content of degraded industrial areas based on the location in the central or peripheral area of the median are identifi ed.

The article analyzes the conditions and background for the introduction of ergonomic research in design process. A man and his activities in terms of production have always been the main subject of ergonomic investigation in order to improve the working environment, tools and working conditions. For more than 60 years of existence, the priorities of the research have changed due to the emergence of new trends and specific problems. It is quite obvious that design and ergonomics are mutually conditioned and their simultaneous study and application are very important.

The article considers the problem of inner city areas of recreational waters of Samara. Their typological relation to town planning grounds, recreational use, sanitary and hygienic condition, landscape and environmental conditions, visual aesthetic and compositional characteristics are viewed.

The objects of research are the earth and unfired clay as building materials used for architectural forming. The article shows the research regarding the traditional techniques of foreign and Russian Earthen Architecture, which offers a new development prospective of architecture of different times. The usage of those techniques allowed the construction of energy-efficient houses, which means that in spite of the weather conditions, the living standard in those houses is quite high and at the same time the use of heating and airconditioning systems is minimized. Building technologies and their historical development are viewed.

Installing chemical power sources in the filter makes the treatment of natural and waste water from organic substances more intense and results in reducing carbonate hardness. The design of the chemical power sources is optimized on the basis of their parameters’ measuring. Electrochemical filters with a number of power sources are described in the article. The process of increasing the effect of water conditioning in the filters can be seen.

Natural observation material of environmental and hydraulic facilities’ conditions during 2012 was considered. Pressure and culvert facilities were visually examined. Conclusions were made and the recommendations were given for repairing and reconstructing the object in order to provide further reliable operation of environmental and hydraulic facilities.

The work production plan of the Iversky monastery bell tower building is viewed. Formwork of dome erection is projected by the authors, concreting procedure is proposed.

Features of corrugated and uneven surface of pipes and grooves and their influence on hydraulic resistivity and heat emission for turbulent currents of liquid flow are analyzed. In autonomous area the resistivity of pipes cannot be found by using a single geometric parameter (equivalent height of roughness peaks), which is typical for even-granular, or sandy unevenness. It is proposed to use several geometrical parameters (d/D, t/D, etc.) for theoretical and experimental study of occurring wave moves in the liquid flow in pipes. Methods and results for modeling wave motions by using different turbulence creators for wall layers (i.e. diametrical grooves, wire ruts and spirals) and precise instruments. Main influence of corrugated and uneven pipe surfaces on structure changes in the wall layers of fluid flow was identified. Practical guidelines for measurements of hydraulic resistivity of the pipes in engineering networks and systems are described.
