The Comparison of Water Indices and Zoning Quality in Karoon and Dez Rivers

Document Type : Research Paper

Abstract
One of the methods can be use in water quality management as a strong tool for decision making is Water Quality Indices. In this article the water quality indices for Karoon and Dez rivers were determined. Where there is less reaction to dicision or this reaction considered in local guideline and also at the times which there are adequate stations and enough sampling frequencies at the right stations, the use of BCWQI indice is recommended. Howere, when one or a few specific parameters are dominated on the decision and these parameters affect directly the infrastructure of sub-indices or total indices and also considering the effect of weighting rate on the reaction the use of NSFWQIm is preferred. The method of using OWQI is the some as NSFWQI with the difference of all parameters have equal value in decision making. The study was carried out during three years started from 2001 and statistical data were taken montly.
