On the topographic control of the urban territory pollution (with special reference to Izhevsk)

Abstract

A schematic map is compiled showing pollution of the Izhevsk city territory. Boundaries and configuration of pollution anomalies appear to depend on specific landforms. Large landforms, such as river valley exert active control over pollution distribution, affecting local circulation. Small landforms passively influence the lower air layer in which pollutants transport primarily proceeds. The layer's thickness in not more than first tens of meters.
