The issue of follow-up support for reservoir resettlement has been a vital social matter in constructing water conservancy and hydropower projects and developing stable society in reservoir and resettlement areas. Correspondingly scientific management of follow-up support information is an important part in the management of reservoir resettlement. The existing problems in the information flow management of follow-up support in the current work pattern are analyzed, that is, inappropriate information feedback, insufficient data processing, lagged information transmission and improper information exchange. In order to promote the scientific and efficient management of follow-up support for reservoir resettlement and to secure the rights of reservoir immigrants, the reservoir immigrants should be placed in the key status in the information work, and a new information flow sharing model with terminal supervision system, which implements sufficient data association and integrity process, is proposed so as to provide information and technical support for the scientific and efficient management of follow-up support for reservoir resettlement projects.
