Abstract

There are as much as 20 rivers and drains in watershed of ANZALI logoon. These rivers carry alarge amount of WASTEWATERS into LAGOON. Because of trophic condition cause undesirable effects for biotic community of LAGOON, therefore the major goals of this study is distinction of pollutant and non pollutant rivers and representation of management programs for rivers and LAGOON. In this study is selected as much as 15 factors such as NH4+, NO2-, NO-3, (K T.P.O -34, O.PO-34, DO, Na+, K+, BOD5, COD, T.O.M and total and fecal coliform. The number of (F, stations for sampling were 21 rivers in LAGOON watershed. This study carried out for 30 months between 1994 - 1996 and in the half of 1998. Measurement of samples was done in monthy intervals. At first for analysis of data determined correlation coefficients between factors and after classification in four clustering. From each clustering was selected one important factor based on f. trophic condition including, T.P.O4-3. T.O.M, DO, Total coliform. For determination of ranking, average in different rivers is used kruskal wallis tests. Ultimately the normalized euclidean model was used to compare the trophic condition in pollutant and non pollutant. The results showed that from total of twenty one rivers. 5 rivers were highly polluted (Pirbazar river was more pollutant than others) and 9 rivers were medium polluted and the other rivers were very lowly polluted.
