Zoning of the White Sea catchment area by the degree of continental runoff influence on the marine environment
Methodologies for the integral evaluation of the potential impact of continental runoff on the marine aquatic environment have been developed and tested in relation to the catchment area of the White Sea. Integral indicators of pollution potential (PP) and self-purification capacity (SPC) of the riv...

Methodologies for the integral evaluation of the potential impact of continental runoff on the marine aquatic environment have been developed and tested in relation to the catchment area of the White Sea. Integral indicators of pollution potential (PP) and self-purification capacity (SPC) of the river waters have been calculated within the boundaries of the hydrologic areas. The following indicators have been used to calculate the PP: the volume of wastewater and the population density in the catchment area (anthropogenic components of pollution), sediment load (a natural component of pollution). Such natural settings of the catchment as the lake percentage, woodiness and the role of topography in self-purification of rivers have been used to calculate the SPC. The quality of river waters, entering the sea, is the result of the ratio of the proposed integrated indicators. On the basis of the quantitative ratios of PP and SPC, the zoning of the catchment area according to the degree of the negative impact of river waters on water quality in the White Sea has been performed.
