A hydrological forecasting system and method based on moisture content monitoring

Abstract

The invention discloses a hydrological prediction system and method based on moisture content monitoring, The system includes an acquisition module, Transmission module, processing module, computing module, A real-time correction unit and a prediction module, The acquisition module is used to collect the actual soil volume moisture information of each representative regional station, the actual soil volume moisture information is sent to the telemetering terminal, the actual soil volume moisture information received is converted into the actual soil volume moisture parameter value by the telemetry terminal, and the actual soil volume moisture parameter value is converted into the actual soil volume moisture parameter value by the telemetry terminal, As that water dispatching automation system acquire the actual soil measurement parameter values in the database server of the measuring and report center station, Flood forecasting model calibrates the parameters of actual soil volume moisture, calculates the available data of soil moisture in early stage by calculation module to generate actual soil moisture, and real-time correction unit corrects the forecasted data in flood forecasting model according to the actual soil moisture. The invention can improve the accuracy of hydrological forecast.

Description

technical field [0001] The invention relates to the technical field of hydrological forecasting, in particular to a hydrological forecasting system and method based on moisture monitoring. Background technique [0002] The development of hydrological forecasting technology has changed from the "Muskingen method", "comprehensive unit line" and "instantaneous unit line" forecasting methods in the 1930s and 1950s to the current Xin'anjiang model, northern Shaanxi model, and water tank model; DEM-based Distributed hydrological model. However, since most of the simulated hydrological forecasting models focus on revealing the objective laws of hydrological phenomena, it is difficult to consider the time-varying characteristics of model parameters and the influence of random factors. With the development of computer technology and cybernetics theory, real-time hydrological forecasting technologies have emerged one after another. , and has developed rapidly, but with the increasing...

Problems solved by technology

[0003] In view of the defects of the prior art, the purpose of the present invention is to solve the problem that the actual water content of the soil obtained in the existing hydrological forecasting system is quite different from the value calculated in the natural state by the hydrological forecasting model, so as to avoid greatly affecting the accuracy of the incoming water forecast
