Background/Objectives: To study the seasonal changes influencing the various abiotic factors in estuaries and shallow coastal waters.

Methods/Statistical analysis: Water sample was collected from Uppanar estuary for a period of one year to analyze various physico-chemical parameters during the study period.

Findings: the present work was carried out on physic-chemical characteristics of water in Uppanar estuary, southeast coast of India during the study period. The findings of physical parameters are: water temperature values ranged from 24.0 to 32.0°C, salinity values of 15 ppt - 36.5ppt, pH values ranged from 8.3 – 7.4, turbidity range 1 to 2000 NTU, TSS (total suspended solid) from 1108mg/l - 1040 mg/l, and DO (dissolved oxygen) range 3.7 to 5.2 ml/l. Chemical parameters of water: NO2 ranged from 0.239 to 3.745 μM/l, NO3 values varied from 3.86 to 12.54 μM/l, TN (total nitrogen), ranged from 9.32 to 28.19 μM/l, IP (inorganic phosphate) values varied from 0.110 to 0.89 μM/l, TP concentration ranged from 1.19 to 32.62 μM/l.

Application/Improvements: The physical and chemical properties of water immensely influence the uses of a water body for the distribution and richness of biota and also influence both vertical and horizontal migration of aquatic organisms.
