A hydrological forecasting system and method based on moisture monitoring

Abstract

The invention discloses a hydrological prediction system and method based on moisture monitoring. The system includes a collection module, a transmission module, a processing module, a calculation module, a real-time correction unit, a prediction module, and a collection module for collecting the actual data of each representative regional station. Soil volume humidity information, the actual soil volume humidity information is sent to the telemetry terminal, and the received actual soil volume humidity information is converted into the actual soil volume humidity parameter value through the telemetry terminal. The actual soil measurement parameter values ​​are acquired within the flood forecasting model, and the actual soil volume humidity parameter values ​​are calibrated by the flood forecasting model. The flood forecasting model calculates the available data of the previous soil moisture content through the calculation module to generate the actual soil moisture content. The actual water content corrects the forecast data in the flood forecast model in real time. 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
