Abstract

The embodiment of the invention provides a hydrological forecasting method and device, and the method comprises the steps: inputting historical monthly-scale meteorological data into a numerical weather generator model CLIGEN, and determining future daily-scale meteorological data according to the historical monthly-scale meteorological data through a CLIGEN model; and inputting the future daily scale meteorological data into a distributed hydrological model SWAT, performing runoff simulation according to the future daily scale meteorological data through the SWAT model to obtain a runoff simulation result, and estimating and publishing long-term hydrological forecast data according to the runoff simulation result. According to the embodiment of the invention, the effective forecast periodcan be prolonged, so that people can more accurately master the global climate change of ten to hundred years or more under the global warming trend.

Description

technical field [0001] The embodiments of the present invention relate to the field of hydrological technology, in particular to a hydrological forecasting method and equipment. Background technique [0002] Hydrologic forecasting refers to the qualitative or quantitative prediction of the hydrological conditions of a certain water body, a certain area or a certain hydrological station within a certain period of time in the future based on the previous or current hydrometeorological data. Hydrological forecast plays a very important role in the basin flood control and disaster reduction system composed of engineering and non-engineering measures. In hydrological forecasting, the longer the effective forecast period and the higher the forecast accuracy, the greater its value for flood control and disaster reduction actions. [0003] In the prior art, the hydrological forecast usually takes the falling precipitation as the starting point, so that the effective forecast period...
