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 m2 in area. On the other hand the Ullal spit exhibits an increase in length of 800 m and an area of 111620 m2. 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.
