Abstract
The present disclosure relates to a method and a device for monitoring the water volume change, and a computer device and a storage medium. The method includes: acquiring a lake shoreline change sequence, a lake area change sequence, and a combined altimetry water level sequence; obtaining a lake water level sequence based on the combined altimetry water level sequence and the lake shoreline change sequence; calculating a first regressive relationship between the lake water volume and the lake water level based on the lake area change sequence and the lake water level sequence; and obtaining a lake water volume change sequence based on the lake water level sequence and the first regressive relationship between the lake water volume and the lake water level.
