Method and device for acquiring runoff data, computer device and readable storage medium

Abstract

The invention provides a runoff data acquisition method and device, a computer device and a readable storage medium. The method comprises the steps of according to driving data of a to-be-measured area and a preset hydrological simulation model, determining the accumulated snow melting water amount, the glacier melting water amount and the accumulated snow layer maximum water holding capacity at the current moment; determining a difference value between the total precipitation of the to-be-detected area and the solid precipitation of the to-be-detected area as a liquid precipitation within a preset time period; obtaining the water holding capacity at the current moment according to the water holding capacity at the previous moment, the re-freezing water amount of the accumulated snow layerat the previous moment and the water holding variation at the previous moment; according to the accumulated snow melting amount, the glacier melting amount, the liquid precipitation amount, the accumulated snow layer maximum water holding amount and the water holding amount at the current moment, obtaining the water holding variation at the current moment; and determining the difference value between the ideal dissolved water runoff and the water holding variation at the current moment as the actual runoff data at the current moment. According to the method, the calculation accuracy of the runoff data of the to-be-measured area is improved.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a runoff data acquisition method, device, computer equipment and readable storage medium. Background technique [0002] With the development of science and technology, people's research on the earth's climate is getting more and more in-depth. As an important part of the global climate system, the cryosphere has an important impact on climate change. Therefore, the hydrological research on the cryosphere is particularly important. As an important research object of hydrological process, runoff data plays an important role in climate change. [0003] In the traditional technology, the measurement of the runoff data of the cryosphere is obtained through the prediction of the traditional hydrological model. [0004] However, the runoff data predicted by traditional hydrological models cannot accurately reflect the runoff data in the cryosphere region, resulting in low accuracy in ...
