| Abstract | Non-Point Source (NPS) pollution in coastal zone are of increasing concern among water environment managers and planners worldwide. In this paper, the long-term impacts of land use change on temporal-spatial variations of runoff, total nitrogen (TN) and total phosphorus (TP) in Dagujia River watershed was studied by jointly using hydrological analysis, SCS-CN method and Pollutant Coefficients Method based on GIS spatial analysis techniques. The results suggest that the runoff volume, TN and TP loads in the entire watershed have significantly increased from 1980 to 2009 and there are great spatial differences among three sub-basins. In addition, the residential area, industrial area and agricultural lands in the watershed are associated with more nutrient loads, whereas forest and grass/pasture with less loads. The information derived from this study can provide good decision supports for coastal land use planning and water environment improvement. |

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.
