Abstract: The Nethravathi spit complex of Karnataka coast consists of Mangalore spit to the north and Ullal spit to the south of Nethravathi-Gurupur river mouth. The integration of topographic sheets and satellite imageries of this area has enabled the evaluation of the migration of spits over a period of 83 years. Morphologically, Mangalore spit has shrunk by 750 m in length and 749780 m<sup>2</sup> in area. On the other hand the Ullal spit exhibits an increase in length of 800 m and an area of 111620 m<sup>2</sup>. The spits show no prominent lateral migration. Shrinkage of the Mangalore spit and the growth of the Ullal spit indicates net northward migration of the estuarine mouth.
