Modeling of Wind Regime in Disturbed Areas Restorable for Urban Development

Abstract

Territory is one of the main values of any nation. Its value is even higher as it is not renewable; meanwhile the growth of productive power, population and construction of cities all over the world keep developing at quick paces.Nowadays, the high level of scientific and technological progress, civil engineering and mineral production leads to the decreased balance of lands and recreation resources while there is a steady rise in demand for out-of-town vacations among big cities residents, and therefore the necessity to implement nature protection activities. These factors make the problems of ecodevelopment and utilization of disturbed areas more and more topical. Under the conditions of the Soviet development in 1961-1970, built-up areas of cities had increased by almost 30 %, principally as a result of alienation of farmlands. Under modern conditions, the expansion of urban areas solely by the account of farmlands becomes impossible.Therefore, one of the principal ways to reduce the territories alienated for housing development is their rational use. As a result of the Soviet urban planning policy in the CIS, the proportion of out-of-use urban territories in the boundaries of modern urbanized areas amounts to about 50 %. The disturbed areas are also considered unsuitable, because they are useless for public economic activities (considering the condition they are in), and also they have a negative impact on human life and activities.In this paper, the experimental results of the airflow process of technogenic relief forms in disturbed areas, in particular of a partially planned refuse heap and of a circular in plan terraced excavation, are given. The obtained results can be used while drawing maps of aeration mode, when the disturbed areas after field mining are used in urban development or for other purposes (housing construction, parks, leisure area etc.).
