Description 73-77
To understand various processes responsible for siltation in the entrance channel and in the sand bar area, near the old Mangalore Port, Karnataka, India, seasonal variations in temperature, salinity, suspended sediment load, currents and extinction coefficient in the Netravathi-Gurpur Estuary and in the sea near the sand bar were studied in relation to tides. Hydrographic characteristics in the estuary showed marked seasonal changes and were influenced by tides to a considerable extent. In the sea, seasonal variations of these parameters were less marked and the effect of tides was not significant. Salinity and temperature at both places were maximum during premonsoon in general. Suspended sediment load was always high in the estuary than in the sea and was maximum in the monsoon season. Currents in the estuary were controlled by tides as well as by the river flow particularly in the monsoon season; whereas currents in the sea mostly followed the general circulation pattern. Extinction coefficient values were higher in the monsoon at both places due to increase in the particulate matter from inland drainage.
