Water exploitation of Karoon River for fish culturing through monitoring and simulation systems

摘要

Heavy metal pollution dispersion simulation in rivers and predicting spatial and temporal variations of pollutants can be used to determine the precise place and to schedule water withdrawal time for drinking, agriculture, aquaculture and ecosystem studies. To study the movement of heavy metal pollution through Karoon flow model, MIKE 11 was employed fpr simulation of the flow model of Karoon River as well as heavy metal moving. The model was run for lead along the 214 km of Karoon River from Ahwaz to Darkhvein. The input data used for this model were river morphology parameters, statistical data of water flow and water contamination. The output of the model conformed to real data collected from different locations along the River. It was concludedthat Karoon River water exploitation for fish culturing (e.g., salmon culture) should be at least 40 km far from Ahwaz (close to Bayoz City) from July to December and 20 km for the rest of the year.
