Moyna block is a remnant of paleo-coast and it is treated under Kasai plain [12]. In the historic past, Moyna was a Mohana region, that is, a place where different water-bodies meet and fall into the ocean. Lithologically, Moyna basin is characterised by recent alluvium of the Quaternary to upper Tertiary period. There is Holocene alluvial lowland, a physiographic division of the Bengal basin of the Ganga-Brahmaputra-Meghna system [13]. Moyna block, a drainage basin, looks like a trough [14]. The physical setup of Moyna is characterised by uneven geomorphological changes particularly in the fields of siltation, soil formation, structure of lands, and drainage system [
