China News Service, March 28. According to news from the Ministry of Water Resources website on the 28th, on March 27, the frozen reaches of the Yellow River in Inner Mongolia were opened to traffic, marking the complete completion of the Yellow River flood forecasting and reporting work for 2023-2024. During the cold flood season this year, the Hydrological Bureau of the Yellow River Water Conservancy Commission issued a total of 135 Lingqing updates, 227 long-, medium- and short-term temperature forecasts, 9 Lingqing forecasts, 17 Lingqing bulletins, and 19 Lingqing weekly reports, and sent approximately 26,000 mobile text messages. times, it received 15.8 million pieces of water regime and water regime information in the Yellow River Basin, forwarded more than 32,000 pieces of water regime and regime information in the Ningmeng-Mongolia testing area, and 315 pieces of measured flow.
The Yellow River Committee attaches great importance to the cold flood forecasting and reporting work, and will produce and release a runoff forecast for the cold flood period in late October 2023 to provide technical support for the preparation of the Yellow River rain prevention plan and the water volume dispatch plan. Starting from November 1st, we will closely monitor the changes in weather, water, and cold conditions, track the changes in temperature and cold conditions, continue to carry out forecast consultations, and analyze and judge the flow, closure, and river closures under different temperature, flow, and river conditions in each measuring area of the Yellow River. Conditions for river opening; rolling release of temperature and storm forecast bulletins, accurate forecast of important storm information such as the first storm in the Ningmeng River section, the date of the first closure and the date of river opening of each section, and complete control of the development process of the storm. Among them, the forecasts for Liuling, Fenghe, and Kaihe are basically consistent with the actual situation. The forecast period for the river opening below Bayangol is as long as 11 days.
On November 12, 2023, the Yellow River Commission launched this year's ice condition patrol work to timely grasp the basic conditions of rivers, bridges, bends, bayonet, dangerous work and changes in river conditions. The Ningmeng-Mongolia survey area adopts the "team combination" model to carry out ice condition patrols on the left and right banks, builds an "air, sky and ground" integrated hydrological monitoring system, conducts ice thickness measurements at fixed ice condition patrol sections, and reports ice condition information and image data in a timely manner . The ice patrol team lasted 137 days and traveled a total of 27,125 kilometers, successfully completing the ice patrol mission during the cold flood season.
Based on actual conditions, each measurement area will increase the application of new instruments and technologies such as drones, electric ice machines, ADCP Doppler current meters, photoelectric sand meters, radar ice thickness meters, video current measurement systems, etc., to ensure a solid Promote technical research on online monitoring of water level, flow, sediment, and ice thickness during the glacial period, and continuously improve the efficiency and quality of ice and flood forecasting.
