| Abstract | Generally, the eco-environmental impacts (EI) systems of large-scale projects, such as the cascade hydropower projects, are complex systems with the characteristics of non-linear and dynamics. However, through integrating information technologies with complex system concepts, the system modeling and operating of complex system could become quantitative and easy to be computerized. This paper adopts UML and system dynamics (SD) as system modeling methods to evaluate and predict the EI of hydroelectric immigration. Specific results include the UML static and dynamic models for retrospective EI evaluation and the SD causal-loop and flow models for EI prediction. The results show: on one side, the retrospective EI evaluation based on UML can generate quantitative and maintainable models with flexible structure; on the other side, the EI prediction process via SD can depict the dynamic and non-linear characteristics of EI system with relatively simple mathematical functions, so that the computerized simulation driven by specific immigration policies could be accomplished. Moreover, both UML models and SD models of complex system can be further computerized so as to promote the automatic operating of EI evaluation and prediction obviously. |

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.
