Abstract

It is necessary to apply suitable management of water resources because of the increasing trend in pollution. Nowadays, industrial regions are major pollution resources of environment, and as such, management of these regions has an important role to play in pollution combat. Correct and scientific utility of all resources can make the most suitable consumption for us. It is important that humans understand the cumulative negative effects of development on rivers, and to develop a program for controlling this serious risk. In this study, quality statistics of Zayanderud river and its corresponding discharge in Varzaneh gauge station was used. Using dependency relationship between flow discharge and water pollutants concentration, the concentration of each pollutant in relation to industry with different probability levels was determined. Results showed that there is a high concentration of toxic elements often times, so river water can have destructive effects on the ecosystem of a region. If river base discharge will be considered on the basis of Q25, then it can reduce elements concentration in normal level, in other words, management programs for industrial regions should be based on the discharge of river because in drought periods, importing element concentration to lagoon will be increased and this has high level of destruction. However, factories waste water and other industrial regions must be changed on the basis of river discharge in drought and wet years. In addition, it is necessary to develop suitable management of industrial regions.
