Biological Studies On Some Ghanats Of Iran, Fardin Oliaei

Masters Theses

The present study was undertaken to monitor the quality of drinking water in the ghanats of Tehran during 1978-1979. Four sites were chosen, and various limnological parameters were investigated.

Physical-chemical analyses were evaluated to determine the composition of the water. There was no significant pollution related to chemical-physical parameters.

Planktonic samples were analyzed with the aid of a Sedgewich-Rafter counting cell. A total of 47 genera were found in all four ghanats.

The planktonic population declined dramatically in winter. Mean diversity and equitability of the algae showed no significant level of pollution and degradation in the study areas.
