Datagov Opendata Platform

Provides real-time water regime data for the Jiaxian Barrage under the jurisdiction of the Southern District Water Resources Bureau of the Water Resources Department. The data includes the operating water level of the barrage, river flow, river turbidity, hourly rainfall, cumulative rainfall, observation time, etc. The water level data is obtained by setting up water level gauges at appropriate locations on the barrage, capturing the water level data of the barrage at every hour, and transmitting it back to the management unit database through the transmission system. After measuring the water level data of the barrage and calculating it based on the width of the river channel, the river flow data can be obtained. The hourly rainfall data is collected from the rainfall observation stations of the Meteorological Bureau in the upstream catchment area, retrieved through the website link and returned to the management unit database. After weighted calculation, the (average) hourly rainfall data in the upstream catchment area can be obtained. The water level station and rainfall station observations are updated every hour. Since the real-time data are the original data of the monitoring instruments, some of the data have not been verified. Users should be careful when quoting and referencing.
