Abstract :

Mighan Lagoon is located in the Central Province, 15 km northeast of Arak and southwest of Dawoodabad. In order to determine the sampling stations of this seasonal wetland, first, it was done in the field, then in the parts where it seems that natural and artificial changes in water quality can be seen, 12 samples were taken and quality points in these samples. became. Using NSFWQI and IRWQISC indicators, the quality status of the lagoon was checked. Also, using the geographic information system, a map of zoning and indicators was prepared. The results of the comparisons measured in summer and autumn showed the errors of biological desirability factors, chemical desirability properties, solution, electrical conductivity, fecal coliform, nitrate, phosphate, hardness, and acidity were more in summer than in autumn. The results of the water surface quality index show that the situation in summer and autumn is in bad and very bad condition. NSFWQI results show that in general the situation in summer and autumn is in bad and moderate condition. NSFWQI index zoning map in the summer and autumn seasons showed that the wetland was recorded in poor quality only in a small area near the entrance of the house.
