Problems solved by technology
[0010] This method is based on the WTF method and uses the rainfall threshold to calculate the parameters. The description of the secondary rain is more delicate, but it cannot deal with the disturbance caused by large-scale pumping and mining, nor can it accurately describe the water supply S

The invention relates to a method for automatically calculating parameters of an aquifer using high-frequency underground water level data. The method comprises the following steps: S1, performing basic condition hypothesis; S2, preprocessing data; S3, performing forward simulation; S4, performing system optimal calculation; S5, correcting data; S6, verifying a model. The method is advantaged in that a calculation method for obtaining important parameters of an aquifer by using a data mining technology is created, long sequence high-frequency high-density underground water level and precipitation monitoring data are used to obtain parameters of an aquifer in which vertical hydrologic cycle is dominant, and the parameters can be updated to an underground water numerical model in real time. The method fully develops operational capability of the underground water model, and provides efficient and accurate technical support for optimal utilization and rational allocation of underground water resources.
Description
technical field [0001] The invention relates to the technical field of water resources assessment, in particular to a method for automatically calculating parameters of aquifers by using high-frequency groundwater level data. Background technique [0002] As an important part of the earth's water cycle, groundwater is one of the most important water storage resources for human beings. Until the 1970s, the groundwater problems faced by my country were mainly driven by pure security needs (such as drinking water and irrigation). However, after the 1980s, China's ultra-high-speed development has become a miracle of world economic development, but it has also brought about many serious groundwater environment and resource problems, such as the deterioration of groundwater quality in the south, and the decline in groundwater levels due to extensive exploitation of groundwater in the northern plains. Wait. [0003] The traditional groundwater flow direction is mainly along the h...
