TECHNIQUE FOR DETERMINATION OF ENVIRONMENTALLY LIMITLY ADMISSIBLE LOADING IN THE DIVISION OF SMALL RIVER BASIN
Based on the equation of hydrochemical balance of water in river basins and one-factor dependence characterizing the relative productivity of semi-submersible water vegetation from river flow and the content of pollutants, a mathematical model was developed to determine the environmentally acceptable maximum load in the catchments of the river basin, including predicting the concentration of water pollutants in the river irrevocable water consumption and environmental flow. Calculations are used to determine the natural ehnogennoy load in small river basins.It is shown that the relative dependence of productivity of water-containing semi-submersible vegetation on the range of variation of the considered environmental factors (), having the form of dome-shaped curves, has the maximum value in the zone of optimal values of the considered environmental factors ( ) . This maximally characterizes the lower limit of the maximum possible value of ecological flow, ensuring the environmental sustainability of the natural system in the catchments of the river basin.
