Copious population growth and anthropogenic activities on earth is changing the natural environment extremely. Hence, an attempt has been made in this paper to determine and identify changes in land-use/land-cover changes and tidal Inundation has been carried out using Remote Sensing (RS) and Geographical Information System (GIS). To distinguish the land-use/land-cover changes and tidal inundation to prepare Geomorphology, drainage, Lithology, soil and contour maps, Satellite Data of Landsat ETM+[1999], IRS-P6-LISS-3[2007], OLI [2014], SRTM data has been used. An attempt has been made to prepared LU/LC maps from remotely sensed data (Land sat ETM+ [1999], IRS-P6- LISS-3[2007], OLI [2014]). Change detection techniques to determine the changes in different types of land-use/landcover features. The results exposed that totally 18 features were identified. Obviously this entire study from the year of 1999 to 2014 has find out settlement (20.69 sq.km) and salt pan (10.61 sq.km) were increased and land without scrub (- 13.08 sq.km), sandy area (-6.57sq.km) were decrease. In addition to that, the tidal inundation of Geomorphic landforms like 5.13, 9.66, 16.74, 23.63 and 32.11 in sq.km , In Land-use/Land-cover features the affected area are 5.17, 9.75, 17.28, 24.11 and 32.02 in sq.km from 1 to 5 meters range. From the study, the mitigation measures (engineering measures) and Coastal Zone Management practices that can be taken to protect human life and property from sea level rise are suggested....
