The present application relates to a runoff reconstruction method, device, computer equipment and storage medium. Among them, the method includes: obtaining the runoff time series measured by the hydrological station, and obtaining multiple Palmer drought index time series corresponding to multiple locations, wherein the multiple locations are determined according to the location of the hydrological station; according to the measured runoff time series time series and multiple Palmer Drought Index time series to obtain the alternative index corresponding to the hydrological station; input the alternative index corresponding to the hydrological station and the reconstructed runoff time series of the hydrological station upstream of the hydrological station into the runoff reconstruction model to obtain the hydrological The reconstructed runoff time series corresponding to the station. It can be seen that, on the one hand, the method uses the Palmer drought index time series associated with the location of the hydrological station, and on the other hand, takes into account the upstream and downstream relationship of the hydrological station in the watershed. The accuracy of the reconstructed runoff time series is improved due to more careful consideration of the statistical relationships among the relevant data for the runoff reconstruction.
Description
technical field [0001] The present application relates to the technical field of water resources treatment, in particular to a runoff reconstruction method, device, computer equipment and storage medium. Background technique [0002] Runoff is an important variable in the water cycle. Long-term hydrological changes and related climate change information are the basis for revealing the long-term evolution of runoff and the development and utilization of river runoff. At present, the monitoring data records of hydrological stations in most regions of the world are relatively short, and the longest historical record of instrumental measurement does not exceed 150 years. Therefore, it is urgent to find a longer historical record of runoff changes. [0003] In traditional technology, tree ring data are often used to extend the time series of river runoff, thus forming dendrohydrology. Dendrohydrology is the science of studying past long-term hydrological phenomena based on tre...
