Abstract :

Udyavara estuary is located in Udyavara basin, Udupi District of Karnataka State, South West Coast of India. The study area in defined by the Tunga basin to the east, the Arabian sea to the west, Sita-Swarna basin to the north and the Mulki Hole to the south. The temporal and spatial distribution of temperature, turbidity, DO, pH, Hardness, TDS and Conductivity of surface water collected from seven different points in Udyavara Estuary were measured and estimated on a post monsoon season. Chlorides and ammonnical nitrogen were collected from 5 different points and measured. There was no change in any of the patterns or any parameter. Each parameter had a specific behavior, However, Pangala station showed the best results. Unlike this the first three stations showed the worst results. The sediment analysis did not show any traces of ammonnical nitrogen.
