Coastal Morphodynamics: Integrated Spatial Modeling on the Deltaic Balasore Coast, India

Various coastal settings like beaches, spit and barriers, deltas, estuaries, lagoons, dunes, red dunes, coral reefs, marshes/mangroves, rocky shore, beach rocks, etc. are incorporated with 7516 km lengthy Indian coast. These coastal morphological units have been developed at different time scale. Coastal setting is undergoing uninterrupted alterations through terrestrial and marine systems. Hence the study regarding coastal environments are gaining momentum among planners, administrators and scientists for better management of the coastal zone. The present studied coast i.e. Balasore coast is characterized by the low lying unconsolidated alluviums surface, extended from Udaipur in the north-east to Rasalpur-I in the south-west which is mostly covered by the sandy, loamy and silty soil with high water retention capacity and this part is also drained by mainly three rivers (Subarnarekha, Dugdugi and Burahbolong). The presence of these fluvial impacts may causes the coastal morphodynamic processes of these areas are very multifaceted in nature. Mobilization of sediment endow with the time-dependent amalgamation apparatus by which this morphologic modification occurs. Morphological changes over time always depend on the nature of fluid dynamics and sediment movement in a particular segment of coastal zone. Progressive adjustment of landscape in turn alters boundary circumstances for the fluid dynamics, which develop to produce further revolutionize in sediment-transport patterns and their depositional yield. Sediment properties and profusion influence the process through their influence upon sediment transport and sediment budgets respectively. This part of the book contains the introduction of shoreline dynamics and beach dynamics and different types of morphological elements and their salient features which have significant importance to modify the coastal region. This introducing sort of the present book is also incorporated with importance of the coastal belt along with the different types of coastal hazard like tropical cyclone, flooding, inundation, storm surges etc. After completion of the study, it also offers some management strategies to formulate the management options for the coastal risk which have frequently kept their worst signatures on geomorphic settings in the coastal environment. © The Author(s) 2016 N.K.
