Introduction. One of the most objective and reliable indicators of the state of pollution of the aquatic environment and the overall level of technological load on it is the content of pollutants in bottom sediments (BS). There are no large industrial enterprises in and around Yaremche-town (Ivano-Frankivsk region), so there are no significant discharges of toxic substances into the sewage system, especially directly into the river. However, every year in this picturesque cornerof Prykarpattia the number of sanatoriums, recreation centres, cottage towns and just residential buildings grows. Accord-ingly, the Prut River, which is the pearl of this region, quite often gets untreated runoff, which pollutes not only water but also settles on bottom sediments.The purpose of this study was to assess the anthropogenic load on the Prut River based on a comprehensive environmental analysis of the state of pollution of the bottom sediments of this river upstream and downstream from Yaremche.Methods. Water extracts from bottom sediments were prepared by the recommendations of the relevant regula-tions in the ratio "bottom sediments - water" as 1: 5 in terms of the dry mass of bottom sediments. Laboratory study of hydrochemical parameters of selected samples was performed by gravimetric, titrimetric, photometric and other methods of analysis.Research results. The accumulation of ammonium salts, nitrites and nitrates, which are easily soluble, in the far above the discharge site of wastewater, is obviously due to the significant sorption properties of river sludge, which prevents these ions from being washed away by the flow. At the point of discharge of wastewater from the city, the content of these ions increases and reaches a maximum at point 3 - at a distance of approx. 100 m below the discharge site. Further downstream, their number systematically decreases. A similar distribution of concentrations is observed in the case of phosphates. Their source of getting into the river also, for the most part, belongs to the housing and communal services. A significant contribution to the increased phosphate content in the sample below the discharge is made by urban wastewater, in which even after treatment the concentration of phosphate ions remains quite high. The fact of the presence of oil products in the bottom sediments at the investigated area was revealed. The constant increase in the number of road transport on the banks of this resort river inevitably leads to the ingress of products of incomplete combustion of fuel, uncontrolled spills.Conclusions. Upstream from the place of discharge into the Prut River of treated wastewater in the city of Yaremche, the concentrations of salts-pollutants of the biogenic group are formed due to uncontrolled sources of domestic sew-age. In this area, the pollution of bottom sediments is insignificant, slightly higher at the discharge site, and they are of the greatest importance below the discharge. This fact indicates the growing anthropogenic impact of coastal cities on the state of the river and in general, and pollution of bottom sediments, in particular. For the first time oil products were found in bottom sediments in the studied area. The reason for this phenomenon is the constant increase in the number of vehicles on the banks of this river.

The purpose of the article is to analyze the state of housing construction in the Kharkiv region and identify factors influencing the dynamics of its development. It is noted that the housing problem remains extremely relevant for the Kharkiv region where there is a large delayed demand for housing. Housing construction accelerates the growth of the gross domestic product of the region, employment of its population, growth of budget revenues. Factors influencing the amount of housing built are not constant and require periodic analysis. Statistical data of housing construction in Kharkiv region are investigated. It is noted that the area of housing commissioned has decreased in recent years. In 2012, half of the total area of residential buildings commissioned in the Kharkiv region fell on the city of Kharkiv. The last three years the area of residential buildings built in other cities and towns of the region is 17–30%. The leaders in housing construction among the cities of regional significance in different years were: Lyubotyn (2014), Izyum (2015, 2019), Kupyansk (2016-2017) and Chuguiv (2018). Among the districts, the most active housing construction is carried out in Kharkiv and Derhachiv districts. It is noted that the volume of construction work performed by enterprises of Kharkiv region in January-June 2020 amounted to 8.9% of the national volume, but the pace of construction of residential buildings decreased by 13%. The index of residential construction products for the first half of 2020 compared to the first half of 2019 amounted to 88%. It is determined that the number of commissioned housing primarily on the amount of capital investment in the region and other factors influencing the dynamics of housing development, such as the socio-political situation in the country, the state of the economy, the availability of mortgage lending and others. The housing programs operating in the Kharkiv region to provide the population with their own housing are considered.

A significant role in ensuring comfortable living conditions in the urban environment is played by the competent organization of the transport and road complex, which is aimed at ensuring road safety, reducing the load on highways for car density and improving the efficiency of traffic in the city when performing planning and technological measures. At the same time, the current state of the city’s traffic flows as sources of increased chemical pollution of the air environment requires an increase in the distance from streets and roads to residential buildings. This distance should be normalized by chemical and physical indicators of the state of atmospheric air and should be taken into account when red lines are established. In this article we analyze: functional state of the city, road network, composition and intensity of traffic flows for Tyumen. The traffic flows of the city are concentrated mainly in the central part of it. A particularly critical situation is formed at the intersections of cargo-loaded main streets at the hours of maximum traffic intensity and on the main highways of the city. We substitute the provision of regulatory requirements for the chemical pollution level at a distance from the border of the carriageway to the border of residential buildings in order to achieve sustainable urban development.

It was shown that urbanized territories contribute to the pollution of bottom sediments of a watercourse by the example of a large river. It was established that the places of localization of the infrastructure of oil refineries, even after their transfer, continue to pollute the environment with oil products, with a periodic excess of the maximum permissible concentration of 20 mg·kg-1. The dynamics of the distribution of oil products in the bottom sediments of a watercourse depends on the meandering of the river, the presence of zones of active operation of the fleet and time of year. The smallest concentrations of oil products was observed at the site located upstream from the studied urbanized area adjacent to the city.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.

Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

The article represents a retrospective review of long time research of genesis and development of the Central beach in the City of Varna which makes possible a forecast of its further development. Both natural and anthropogenic impact on the beach evolution is taken into consideration. It is ascertained that construction of coastal protection structures at the northern part of the beach in 80’s resulted in cessation of natural beach area growth. The strengthen of a breakwater in the main port and illegal building also contributed to considerable coast recession and beach volume reducing. Because of this a recreational potential of the Central beach is gradually decreasing. New method named “cross-shore sediment bypassing” is suggested to reduce the negative trend.
