Abstract

Chemical and biotic indices of water quality have some problems. They need a lot of time to measure and technology, therefore we considered evaluating water color objectively and quantitatively. This method is as follows; after filtering sampling water on the glass fiber filter, absorbance spectrum of this filter is measured by the spectrophotometer. This method does not need, technology and cost. We surveyed the relation between absorbance spectrum and conventional water indices. As a result, this method is very effective to evaluate water quality change from the water color point of view abd it can also evaluate turbidity and Chlorophyll-a very easily. We expect this method to lead to a new water quality index.
