Improvement of the Application of Electronic Water Gauge in Complex River in Chengde City
ZHAO Fuxiang
Abstract：Considering the impact of sediment concentration and river morphology on water level readings by electronic water gauges in meandering,sediment-rich rivers,the Chengde Hydrological Center has developed a cascading,multi-stage electronic water gauge.To validate the effectiveness of this monitoring system,water level data from both manual observations and the electronic water gauge at the Sandaohezi Hydrological Station in Chengde during the normal and flood seasons of 2021 were analyzed.A comparative analysis revealed that the water level measurements obtained from the electronic water gauge closely matched those from manual observations,showing a significant correlation between the two datasets.Upon thorough review and analysis,the findings met the criteria set forth in the'Water Level Observation Standard',confirming the reliability and accuracy of the electronic water gauge system.
