Description Present study of the coastal changes in Tadri, Uttara Kannada district of Karnataka, comparing Survey of India Toposheet, Coastal Zone Management Plan of Karnataka and traditional ground survey measurement merged with multi temporal satellite imagery (IRS-P6, LISS III, 2011) This analysis gives the result of erosion from year 1978 to 1996 is 7.83 km2, during this period no accretion is noticed Comparing data set of 1978 with 2011, area of erosion increases to 8.45 km2, and accretion by 0.15 km2 And from 1996 to 2011 it is seen erosion of 3.61 km2 and accretion of 3.05 km2 Erosion is observed in the northern bank of Tadri river, the probable cause of erosion is tidal action along the earthen embankments results in breaching and due to this flood are occurring in the adjacent area, and an accretion is noticed at the mouth result in narrowing the shape, due to sediments brought from upper reaches of Tadri river The present studies give a scenario of changes and may help authorities to prepare the better Integrated Coastal Zone Management Plan for coastal protection and further developments.
