Abstract

The invention provides a method for monitoring response of a hydrological process to climate change based on an SWAT model. The method is characterized by comprising the following steps: step 1, acquiring various data of the hydrological process; step 2, establishing a corresponding SWAT model; and step 3, applying various data to the SWAT model, and performing response analysis and monitoring ofthe hydrological process to climate change.

Description

technical field [0001] The invention relates to the technical field of hydrology and climate monitoring, in particular to a method for monitoring the response of a hydrological process to climate change based on a SWAT model. Background technique [0002] The SWAT (Soil and Water Assessment Tool) model was developed by the Agricultural Research Center (ARS) of the United States Department of Agriculture (USDA), and it is more suitable for long-term distributed hydrological process simulation for water resources management. The effectiveness of the SWAT model has been proven. For example, the existing technology includes estimating and comparing the base flow in the runoff of river basins based on the SWAT model and digital filtering technology. The results show that the model has a high accuracy in simulating the base flow. In addition, the SWAT model was used in the Lushi River Basin to conduct runoff and sediment simulation experiments in mesoscale watersheds, and it was c...
