| description | Occurrence of factors such as decreasing atmospheric precipitation, population growth and industry progress has increased the importance of paying attention to the proper quality management of water resources. Pollution sources are categorized in different aspects. In this research, controllable and uncontrollable pollutant management is considered. To manage and control the damages caused by each of these types of pollutants, a certain qualitative tool is employed. Assimilation capacity is suggested when the pollution source is controllable and dilution flow is the proposed tool of this investigation to uncontrollable pollution management. To analyze and calculate the above mentioned qualitative tools, the simulation process is used by analytical solution of the advection-diffusion equation. The case study considered in this research is an area with specific characteristics, which has been investigated by many previous researches. Efficient indices in determination of qualitative tools including mean area of unallowable concentration (¯(c_a )), affected distance (X) and duration of unallowable pollution concentration contact with river (T) were calculated in each simulation process loop. The results demonstrated that 94.1% variation of river-reservoir flow discharge can change the assimilation capacity up to 99.3%. Moreover, by applying a suitable dilution flow, 10 and 20 tons of sudden contaminants arrived at the permitted concentrations of 0.5 and 1 mg / l over the river. In this process, values of the crucial quality parameters of the river ((c_a ) ̅، X و T) change up to 96.6%, 92.2% and 53.7%, respectively. |
