Influence of Anthropogenic Load in River Basins on River Water Status: A Case Study in Lithuania
نویسندگان
چکیده
Twenty-four rivers in different parts of Lithuania were selected for the study. The aim research was to evaluate impact anthropogenic load on ecological status rivers. Anthropogenic loads assessed according pollution sources individual river catchment basins. total nitrogen (TN) values did not correspond “good” and “very good” classes 51% tested water bodies; 19% had a “bad” “moderate” BOD7, 50% NH4-N, 37% NO3-N, 4% PO4-P. phosphorus (TP) bodies. largest amounts basins generated from following sources: transit pollution, with 87,599 t/year 5020 phosphorus; agricultural 56,031 2474 phosphorus. highest per year, average, accounting 53.89%, 34.47%. also totaling 58.78%, 28.97%. Multiple regression analysis showed activity biggest negative influence all studied indicators.

متن کاملWater quality modelling for small river basins
Water quality modelling in small rivers is often considered unworthy from a practical and economic viewpoint. This paper shows instead that a simple model structure can be set up to describe the stationary water quality in small river basins in terms of carbon and nitrogen compounds, when the use of complex models is unfeasible. In short rivers point and nonpoint sources play a key role in shap...
