    "The deltas are the most dynamic parts of a coastal region witnessing high rates of sedimentation, responding to the coastal evolution in response to sea level changes and tectonic. Delta-related deposits usually have a high potential of hydrocarbons as stratigraphic traps.

    The book offers a comprehensive account of deltas and geological evolution of East Coast of India since its separation from Antarctica-Australia assembly and the present situation of Bay of Bengal. Oceanographic processes, sedimentation, depositional patterns of coastal zone, continental margin and Bengal Fan are discussed. The East Coast of India shows a number of small and large deltas with varying hydrologic characteristics. Seven important deltas of the East Coast, namely Ganga, Subarnarekha, Mahanadi, Godavari, Krishna, Penner and Cauvery are discussed in detail. Geomorphology, river mouth processes, depositional environments, vertical facies model and sand distribution pattern of each delta are given. This information is useful to develop hydrocarbon exploration strategies for a variety of delta systems.

    The book is the only available comprehensive account of the East Coast of India and its deltas, emphasizing possible delta building activity of different East Coast of basins in geological past, Holocene evolution of deltas, response to changing sea-levels and systems tract concept.

    The book is useful to hydrocarbon exploration geologists engaged in delta systems, oceanographers, physical geographers, geologists and land planners of coastal areas."
