Классификационные признаки городских водоемов

Abstract

A system of indications meant for new classification of urban recreational water bodies based on a vision of an urban water body as the most important component of the city infrastructure. At the same time it is necessary to take into account that an urban water body is a hydraulic facility affected by water impact and characterized by the lack of methodical literature for designing. In a city a water body is more than often represented by either pond or earth reservoir. It is necessary to consider them as special water bodies. A set of appropriate classification indicators is proposed as a basis for such kind of analysis and development of the principal approaches. These indicators enable to characterize the currently existing urban water bodies and those to be designed in accordance with different parameters. This system of indicators is balancing between practical necessity for a concrete classification indicator and its relative simplicity. The following indicators have been adopted as the classification ones: the water body type, level of its territorial hierarchy, its area, average depth, cascade level, bank protection structure, as well as the feeding system. The classification indicators system was preliminary tested at 35 ponds of Moscow, this has enabled to obtain the general idea of the applied approaches.
