Abstract | A 3-D Marine Environmental Committee (MEC) model was conducted to describe the specific circulation patterns of hydrodynamics of water quality and ecosystems driven by climate change forcing in Kamaishi Bay at Miyagi Prefecture in the Great East Japan. The major concern of this study is the diffusion of pollutants caused by 2011 Earthquake and Tsunami disaster impacts on marine ecosystem. In this study, we simulate the changes of water quality and ecosystems structure from January 2009 to December 2012. The MEC model has been used to predict the distributions of various key water quality indicators and tide flow in the different layer of Kamaishi Bay. High correlation is obtained between simulation derived and measurement derived tidal characteristics. We also simulated the effects of breaking water effects on the tide, currents and integrating aquaculture and fisheries. The wind driven flow using mean seasonal wind forcing (NE, SE, and SW) creates different circulations over Kiamichi Bay. Similarly, the temperature and salinity distribution of Kamaishi Bay waters is characterized by strong seasonal variations. The water quality is intensely affected by pollutants and has continually deteriorated due to increased discharges of domestic and industrial waste as well as an increased loading in anthropogenic contamination into the Bay. The results were found that measured and simulated contaminations of radioactive materials were under the environmental standards in Japan. Observed and simulated DO, T-N and T-P concentrations were not so large different from those before the disaster. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
