Abstract:The video surveillance of water scenes has an important influence on the management of water resources. An intelligent water video surveillance system is proposed in this paper .This system is consisted of two parts, the front part and the center part. 3G network is used between the two parts for communication. Video capture, storage, forwarding and analysis are finished by the front part. The center part receives the analysis data and the video from the front part and store them, also this part makes it possible to view the real-time video of the water scenes and finish the management of the various front parts.The result of a long-time running shows that this system can monitor water scenes stably for a long time,also,it can get the key information about hydrology and water resources of those water scenes accurately,in the end,this system has a great value in the management and scientific decision-making of water resources.
