Abstract

The physically based ECOMAG-HM model, developed to simulate heavy metal cycles in large river basins, was used to study the spatial and temporal regularities in the formation of copper and zinc distributions in water bodies in the basin of the Nizhnekamskoe Reservoir. Maps of the mean annual concentrations of the metals in river network and the mean annual modules of diffuse runoff with its genetic components have been compiled. The contributions of point and diffuse sources to river water pollution by copper and zinc have been evaluated. To specify the estimates of the effect of economic activity on river water pollution, numerical experiments have been carried out to simulate the scenarios of an increase in the amount of metals discharged as wastewater components, wastewater emergency volleys, and complete elimination of anthropogenic impact on a drainage basin.

Nizhnekamskoe水库盆地水道中重金属污染的模拟

摘要

基于物理的ECOMAG-HM模型，用于模拟大型流域中的重金属循环，用于研究Nizhnekamskoe水库盆地水体中铜和锌分布形成的时空规律。编制了河网中金属的年平均浓度图以及弥散径流的年均模量及其遗传成分图。评价了点源和扩散源对铜和锌污染河水的贡献。为了详细说明经济活动对河流水污染的影响，进行了数值实验，以模拟作为废水成分，废水应急排污物排放的金属量增加的情景。
