Application background of Rivers and Lakes water level online monitoring station
In recent years, extreme weather occurs frequently, and disasters such as rainstorm, flood and drought have increased the threat to Rivers and Lakes. The traditional artificial water level measurement method has problems such as low frequency, large error and slow response, which is difficult to meet the needs of real-time early warning and scientific decision-making. At the same time, with the advancement of water conservancy informatization construction, accurately grasping the water level change trend of Rivers and Lakes has become the key to ensuring flood control safety, optimizing water resource allocation, and maintaining water ecological balance. In this context, the online monitoring station for Rivers and Lakes monitoring water level, relying on high-precision sensors and the Internet of Things technology, realizes automatic collection, real-time transmission and intelligent analysis of water level data all day long, which can not only capture the flood rise in advance, provide data support for reservoir flood discharge scheduling, but also dynamically assess the water resource status in dry season, helping water conservancy departments improve disaster prevention capabilities and water resource management efficiency.
