Abstract
Estuarine morphology discusses the impact of transition zone between fluvial environment and marine environment. The dynamic change of the morphological relationship with environmental variables throw light to Namkhana Abad as selected study area of the south-west part of Sundarban, India. The Namkhana area is very prone to cyclone attack and has been affected by devastated activities of high magnitude cyclones (particularly Aila Cyclone of 2009) along the shoreline for its vulnerable characteristics in the previous decades. The rapid change has been observed in Land Use & Land Cover and Drainage area for understanding the spatial changes due to the cyclone effect. The drainage map has been generated on the basis of ASTER DEM of two years 2005 & 2010 for the comparative analysis of drainage degradations. The Land Use and Land Cover change have been generated using supervised classification techniques with the geospatial data of 2005 & 2010 and ground truth verification. These temporal changes helped the present study to observe the Aila cyclone effect with comparative analysis of two years for the establishment of the relationship between drainage and LULC as environmental variables. The above study reveals that the coastal fringed paddy fields and mangrove forests are heavily degraded by salt water encroachment and erosion with the impact on the local people of the study area forcing them to modify their land use conversions. Today the salt affected paddy fields are converted into land for aquacultural practices by the local people as rapid adjustment with the environmental variables.
