為積極迎向未來物聯網的應用時代，水利署積極推動科技防災，並推動智慧河川管理，以流域整體治理新思維，規劃智慧河川管理系統；藉由開放資料及相關感測器收集大數據，並結合物聯網技術，從前端資料自動即時監控、中端資料傳輸及整合、後端資料分析加值應用乃至管理決策判斷等分項逐步建置，以提升河川管理、水文監測、水災預警與預報及有效管理水資源等智慧管理能力。

Extreme rainfall events have spread frequently by climate change in recent years. In addition, there are many uncontrollable factors such as earthquakes in Taiwan, causing huge disaster . In order to ensure the safety of people's lives and property, reduce disaster, and actively the application of the Internet of Things in the future, the Water Resources Agency actively promotes scientific and technological disaster prevention, and promote smart river management, and use the new thinking of overall governance of the region, and plan the smart river management system. The main purpose of the smart river related plan is to arrange the Hydraulic Sensor Instruments, Planning the Communication Network Architecture for Smart River, and Planning of the Smart River Management System. The more complete of the monitoring information, the higher credibility of subsequent applications. Through the basic survey and analysis under the area of the 8th River Management Office (8th River Management), the plan has completed relevant hydrological observation stations (rainfall station, velocity station, water level station, tidal station, flood sensor, seawall tracer, groundwater observation well, etc.) in Beinan River. sensors for hydraulic structures (water gates, mobile pumps and dangerous potential dike sections), water resource management information (dams, river diversion points, water rights management, groundwater wells, Drainage system, irrigation system) and river channel 3D numerical model inventory work can be used as a basis for hydrological observation and hydraulic structure sensor layout planning. In the evaluation and planning of the hydrological observation sensor deployment, the rain station is analyzed by the Thiessen's polygon method for rainfall station network. It is recommended that a new measurement station is not required for a short distance. It is also recommended to set up a redundant monitoring water level in Taitung Bridge and Luming Bridge station:The Taitung Bridge is mainly due to Taitung urban area as the main object of protection and is prone to high disaster situations. A backup water level station is required to prevent data loss. In Luming Bridge, when BAILU typhoon hit Taiwan the water level exceeding the first warning level, and the signal transmission was unstable. A backup water level station was also required to prevent data loss. A new water level / flow station can be set up at Luliao Bridge, and a new water level station can be set up at Shinwuling Bridge to grasp the water level change of Luliao River, provide more data for the river water simulation accurate, to the target for the flood early warning. There were 29 locations to plan setup flood sensor. And suggest that tidal station and seawall tracer not necessary to set. The layout and evaluation of sensors for water structures are recommended. An opening meter is recommended for Ruihe drainage gate. Due to its high economic development and large scale, the current power supply method is diesel generators. If sensors are required, It is necessary to have a more stable power source to operate with long-term power supply and sensors; Riverbed scouring and dike safety management: the flood control points of the disaster-prone river section, after 5 sites are surveyed, 21 construction sites are planned setup in order, it is recommended to monitor the operation of the mobile pumper unit as the unit's operating information, mainly based on positioning and engine signals. The digital image application plan is divided into two parts: rivers and urban flood. One part of the river can be built at Luming Bridge. Because the water level in Typhoon Bailu has exceeded the first warning level, it is recommended to add CCTV to assist the water level station observation, real-time status and water level. The monitoring system of the equipment part is planning a rotary camera and a fixed camera to facilitate the fixed monitoring of the water ruler and the inspection of the surrounding water conditions. The plan is to build a demonstration area for pavement flood sensors and a riverbed scour monitoring and embankment safety monitoring demonstration area based on the requirements of the 8th River Management office. At the intersection of the of Zhonghua Road and Guiyang Street, a B-type sensor capable of directly transmitting the IoT of water resources is set up, and five A-type sensors are set up near the lower place for subsequent mode verification ; In addition, riverbed scour monitoring and dike safety monitoring were installed at inclinometers and wireless scouring particles on sections 57 and 58 of Beinan river, and a base station was set up on the shore to receive real-time data on riverbed scour and dike safety. The Beinan River Basin communication network plans to use NB-IoT dual networks or two telecommunications to provide one NB-IoT and one 4G transmission with a mutual backup transmission channel. Based on the existing flood control operating system of the 8th River Management, the monitoring data is transmitted to the Water Resources Angecy to provide resources and services using standard communication protocols such as RESTFuL, MQTT, WebSocket, or Kafka. In addition to supporting the policies promoted by the Water Resources Agency, with the new thinking of overall river basin governance, integration and introduction of IoT transmission technology, planning and evaluation of the smart river management system suitable for the future of the 8th River Management, including related requirements, architecture, functions and Feasibility and funding of various equipment and technologies, provide the follow-up system construction and the application and development of the Internet of Things technology in the smart river to facilitate the decision-making basis for the subsequent overall river basin management, management, and flood prevention, and to achieve the purpose of smart river management.
