Abstract
The water quality parameters of Sulur Lake situated in Coimbatore District of Tamil Nadu (11° 01' 40” N and 77° 07'20” E) have been studied from July 2015 to July 2016. The present paper dealt with the seasonal variation of productivity and its relation to Total Dissolved Solids (TDS), Chloride and Magnesium. In the present study, Total Dissolved Solids of the six stations varied from 490 mg/l to 950 mg/l, Chloride ranges between 249.92 mg/l and 445.88 mg/l and Magnesium varied from 20.9 mg/l to 65.2 mg/l during the study period. Gross Primary Productivity (GPP) ranged from 1.3601 gC/m3/hr to 3.1736 gC/m3/hr, Net Primary Productivity (NPP) varied between 0.7556 gC/m3/hr and 2.8713 gC/m3/hr and Community Respiration (CR) varied from 0.1511 gC/m3/hr to 0.9067 gC/m3/hr. The data on the physico-chemical characteristics of this aquatic wetland revealed that this water body needs immediate and broad water quality monitoring and to find the remedial measures to improve this important water body in the study area. The mathematic relationships of these factors were analyzed using CURVEXPERT software and the significant relationships are expressed and their significance in the prediction of water quality is discussed
