Application of Radar Level Meter in River Level Monitoring

Background

River flood control level monitoring is a crucial step of flood control system. It mainly focuses on real-time monitoring of water level changes in rivers, lakes, reservoirs and other water bodies to achieve the following purposes,
1. Natural disaster prevention: flood is one of the common disaster around the world, causing huge casualties and property losses. Real-time monitoring of river levels can provide timely warnings of floods, providing local governments and residents with time to evacuate and prepare, thereby reducing potential damage. 
2. Water resource management: River level change is not only relative with flood control, but also has the close relationship with reasonable utilization of water resources. For example, during droughts, water level monitoring can help managers understand the status of water resources, rationally dispatch reservoir water release, and ensure agricultural irrigation and urban water supply downstream. 
3. Ecosystem protection: The health of river ecosystems is directly dependent on stable hydrological conditions. Water level monitoring helps track long-term trends of the river level, assess the impact of climate change on water environment, protect biodiversity and maintain ecological balance.
4. Infrastructure safety: the infrastructures near rivers, like bridges, roads, houses, are easy to be threatened by flood. The water level monitoring system can predict possible level rises in advance, and help engineers to take measures to reinforce or protect these facilities to avoid or reduce damage.

Solution

For the river flood monitoring industry, we analyze customer needs and common installation conditions on site to provide the following solutions,
1.Device selection：The solution adopts 80G IP68 radar level meter as core monitoring devices. 
The radar level meter has the characteristics of non-contact measurement, anti-interference, easy-to-maintenance, which is suitable for complex and changeable river environment.
2.Installation and deployment: Radar level meters are installed at selected monitoring points along the river bank to ensure coverage of key water level change areas. At the same time, considering the stability and environmental protection of the solar power supply system, each monitoring station is equipped with solar panels to achieve self-supply of green energy.
3.Data transmission and processing: GAMICOS GRT102 wireless terminal is adopted to send the water level data collected by the radar level meter to device management platform through wireless network.
4.Early warning mechanism：The system automatically triggers an early warning signal based on the preset threshold. When the water level approaches the warning line, it promptly notifies relevant departments and personnel via text messages, phone calls, etc. to make flood prevention preparations in advance.

The system structure is as follows

Application

Background

A district in Indonesia has large amount of rivers and well-developed water system. In recent years, due to the frequent occurrence of extreme weather caused by climate change, flood disasters have become a focus of attention for local governments and residents.In order to effectively respond to possible flood threats, the local government decided to introduce advanced water level monitoring technology to improve the accuracy and response speed of hydrological information.

Effects

1.Realize all-day and unattended river level monitoring, greatly improving monitoring efficiency and accuracy.
2.Real-time transmission and analysis of data provide timely decision-making support for the hydrological department and reduce losses caused by information delays.  
3.Through the early warning mechanism, the risk of flood disasters has been effectively reduced and the safety of people’s lives and property has been protected.
