The risk of flooding in urban environment has become more and more frequent due to the increased impervious surfaces and climate change. The most suitable solutions for mitigating the urban flooding risks are stormwater detention tanks which temporarily store the exceeded rainfall and gradually release it into the urban drainage system at the end of the rainfall events. The present study aims to evaluate the feasibility of stormwater detention tanks used also for producing hydroelectric power serving a small town, through the release of such volumes. The study is applied to an urban watershed in the city of Cosenza, Italy. After a preliminary design, a hydrologic/hydraulic model, SWMM, coupled with a numerical model implemented in MATLAB was used to predict the stormwater volumes reusable for the production of electricity and the overall response of the system on annual basis. The results obtained showed that a mini-hydro system in an urban area is technically feasible. From an economic point of view, the system is self-sustainable only if one considers the need to integrate the urban drainage network with the electric power grid using the stormwater volumes to store energy in hours of maximum electric energy production that otherwise would be lost.

Cultural Role

One of the criteria for a comfortable ecologically clean urban environment is access to green spaces, their number and quality in any given city. Public green spaces play an important socio-cultural role in the context of active and passive recreation of citizens, various types of recreational activities. The relevance of this study is due to increased attention to the formation of open public spaces in the city of Krasnoyarsk. The purpose of this work is to trace the evolution and identify the social and cultural significance of the green public spaces in Krasnoyarsk. The objectives of the research are to study the green spaces of Krasnoyarsk in a historical retrospective, analyze the green spaces of Krasnoyarsk from the point of view of their ecological significance, recreational use. Research methods included literature review on the topic, analysis of historical data, field survey of the territory, long-term observation, photographic recording, comparative retrospective analysis, and graphic-analytical method. The study captures the most common types of public green spaces and their role in creating a comfortable urban environment. It traces in the most detail the evolution and cultural significance of the most important historical green spaces in Krasnoyarsk: the City Garden (now the Central Park), Yudinsky Garden, Krutovsky Garden. These examples show that gardens and parks can be formed both on the basis of the natural environment of urban forests, and artificially created by the efforts of citizens, that over time they can undergo various quantitative and qualitative, planning and functional transformations. Despite the transformations that have taken place, all the studied historical objects still exist and are used for their intended purpose. In addition to these historical green areas, we examine the newly organized public green spaces with a cultural and recreational component over the past decades: Tatyshev Park, All-season Fun-Park Bobrovy Log, Flora and Fauna Park Roev Ruchey, Dream Gardens and others. The article notes the importance of municipal, public and private initiatives in the organization of local green areas. The analysis allows us to assert that there is a certain system of public green spaces in Krasnoyarsk. It has disadvantages, such as an uneven distribution of green areas throughout the city, lack of interconnections between individual elements, aging of certain areas of greenery, and the complete destruction of some. Nevertheless, the city authorities, architects, designers and the general public make great effort to create a green framework for Krasnoyarsk destined to have an important recreational and cultural role.

<p>Reducing the number of city-forming enterprises in single-industry towns leads to a decrease in the standard of living and migration of the population to other cities. From the economic point of view in many cases, the support of such cities is inappropriate, and there is a need to support the most rapid migration of the population to<br />more favorable cities. But on the other hand, the dispersal system in Russia is characterized by sparseness, and in many cases isolated monocities are important for the integrity of the territorial structure of the country. The article identifies the main factors that can<br />influence the increase in the attractiveness of single-industry towns for the population. This approach can be an effective tool for assessing the potential of single-industry urban settlements. Approbation of the proposed campaign in the Republic of Tatarstan<br />and the Kemerovo region made it possible to conclude that the strategic direction in the development of single-industry cities should be connected with the economic diversity of the city. Acceleration of economic growth, as well as sustainability of business can be<br />achieved by the development of small and medium-sized businesses</p>

The article deals with the ecological and economically balanced functioning of combined drainage systems on heavy soils of the Novgorod region. The water-air regime of the drained lands and the parameters influencing it (a drainage drain, a level of ground waters) is considered as an ecological indicator, and economic – increase of productivity of lands. The studies were carried out at the experimental experimental field, drained by closed drainage with backfilling of the drainage trench of the sand-gravel mixture to the arable horizon (control), two-tier drainage and a combination of with deep loosening. The analysis of the results of the study showed that the experimental combined drainage system was set aside 88% more runoff compared with control; in the excessively wet growing season (25% probability of precipitation), the system of two-tier drainage there was the lowest level of groundwater and soil moisture; the effect of deep loosening began to decrease by 3 year of operation of combined drainage, so it is recommended to carry out deep loosening on loamy soils every 3 years; from the ecological and economic point of view the most balanced option is the combined two-tier drainage.

ABSTRACT The observed changes in extreme weather events reflect the influence of climate change caused by anthropogenic factors, in addition to natural climate variability. According to future climate projections, the increase in the average surface temperature will cause major changes in the average annual rainfall of almost the entire planet. The primary objective of this study is to evaluate the impact of possible scenarios of climate change on urban drainage system in locations situated at low latitudes. The specific location of the study was one of the Rio Cocó sub-basins in the city of Fortaleza-CE. It was used rainfall data generated by 6 (six) different global circulation models: bcc-CSM1, CanESM2, CCSM4, CESM1-CAM5, inmcm4 and MIROC5. These data were extracted and interpolated to the city of Fortaleza-CE. This information was used in order to generate new IDF equations designed for the future, by using the “Equidistance Quantile Matching Method”, based on climate projections RCP 4.5 and RCP 8.5. The new values of rainfall generated by these new IDF curves were used as input data to HEC-HMS program, which is capable of calculating flow and volume disposed in a particular basin. The results showed that large increases in flow rates and volumes disposed in the analyzed drainage system will occur, and that the RCP 8.5 scenario presented even more pronounced values than the ones generated by the scenario RCP 4.5.

The article examines the features of the perception of the urban environment as a specific phe- nomenon. The article considers the artistic works of a group of contemporary Ukrainian artists P. Makov, A. Sai, L. Dzhuraev, A. Priduvalov in the genre of urban landscape from the point of view of a conceptual approach, which allows us to understand the general direction of development of this type of genre. The works of contemporary Ukrainian artists reflect how a modern city creates an endless combination of connections between different aspects of life and the corresponding various forms and impressions. The article analyzes the works that the authors demonstrated as their reflections on changes in the urban environment in special creative projects. The urban environment causes a creative person to strive to convey his atmosphere, images, rhythms in his own language. For centuries, artists have depicted the urban space, but it was in the twentieth century that the transformation of the urban environment into an urban one contributed to the fact that the city became a source of special inspiration for subsequent times. The theme of urbanism is specific in the work of contemporary Ukrainian artists, where the very phenomenon of the city is the basis of creative inspiration. The aim of this work is to study the conceptual and programmatic works of contemporary Ukrainian artists to reveal the theme of urbanism in painting and the main trends in displaying the city as a concept in the work of artists.

With the emergence of excessive flooding in the urban environment, the need for unconventional drainage control measures within the limitations of conventional solutions becomes evident. In the present study, infiltration trenches and reservoirs that collect and reserve rainwater were designed as control devices, attenuating the socio-environmental impacts caused by waterproofing of urban areas in the hydrological cycle and in the behavior of the hydrographic basins in question. The measurements were made for two flooding points found in the city of Carazinho – RS, located on Marquês do Pombal Street and São Bento Avenue, due to the obstruction of gutters and street inlets, paving and waterproofing of the ground due to urbanization, lack of maintenance and cleaning of the micro drainage system along with the inability of the system to collect all the volume of water from the runoff. The reductions in flow rate in these areas through the use of trenches were 16% and 15% for the first and second flooding point, respectively, while the use of the delay reservoirs together with the infiltration trenches resulted in a 29% reduction in the first flooding point and 27.5% in the second flooding point. Therefore, it is evident that the use of unconventional control measures is vital to the reduction of the peaks of the flow rate and control of the surface runoff.
