Variability effect of hydrological regime on river quality pattern and its uncertainties: case study of Zarjoob River in Iran

River water quality assessment, affected by pollution load, and river regime changes in various climate conditions, is an implementation that simplifies water resources management, and justifies terms for increases or decreases in human activities. The current paper aims to offer a water quality mod...
