- Аннотация: Together with regular atmospheric pollution monitoring, catchment analysis studies are performed within EANET region (East Asia) for selected areas. These include evaluation of datasets on measurement pollutants and nutrients in all environmental media within small watersheds. Precise estimation of chemical compound runoff is one of the crucial factors for the adequate evaluation of nutrient/pollutant budgets of small river catchments affected by atmospheric pollution transport or regional climate change. Yet most of monitoring programs based on extensive networks do not allow performing long-term intensive sampling and chemical analyses due to cost effective constrains. A case in point is the regular sampling of river water at one of EANET monitoring sites, Primorskaya, which is conducted mere five times per year, in compliance with conventional recommendations on inland aquatic monitoring for streams in temperate humid climate. Such temporally sparse data is subsequently processed using the runoff interpolation method (IR) for pollutant runoff estimation, which provide results with a rather low degree of accuracy and often is not enough appropriate for catchment budget calculations.
