SEASONAL VARIATION IN SEDIMENT ANALYSIS OF RAJAKKAMANGALAM ESTUARY OF SOUTHWEST COAST OF INDIAV.N. Hameetha Banu, P. Mohideen Askar Nawas, H.F. Seyed Mafiya Haniff
The monthly and seasonal variations of physicochemical parameters of sediment were studied from January 2015 to December 2015 in Rajakkamangalam estuary (Latitude: 8Â° 114âN; Longitude: 77Â° 38âE) of southwest coast of India. The pH ranged from 5.90 to 8.65. EC showed irregular patterns of distribution from 0.14 ds/m to 1.20 ds/m. Total nitrogen ranged between 21 ppm to 360 ppm. The values of organic carbon and total phosphorus ranged from 0.035% to 0.750% and 0.21 ppm to 0.240 ppm. Soil texture value also highly fluctuated. The values of sediment sand, silt and clay ranged from 58% to 88%, 24.5% to 6.0% and 4.5% to 24.2%. The seasonal variation revealed that pH, EC, total phosphorus and soil texture were more in monsoon and less in nonmonsoon season. A significant positive correlation was obtained from various nutrients of the selected sampling station of the experimental estuary.
