Abstract
(EN) Disclosed in the present invention is a satellite big data-based continuous measurement method for river flow. The method comprises: a flow testing river section determinization method, a satellite big data river cross-section reconstruction method, a multi-satellite information coupled real-time water level calculation method, and a flow calculation and compilation method. By means of the present invention, the problem of a test difficulty or the continuous measurement of flow of rivers in depopulated zones can be solved, and the blank of a satellite flow testing method based on the principle of river dynamics is filled, such that the range and density of river flow testing are greatly improved.
(FR) La présente invention concerne un procédé de mesure continue par satellite basé sur des mégadonnées, appliqué au débit des fleuves. Le procédé comprend : un procédé de détermination de section de fleuve pour le contrôle des débits, un procédé de reconstruction de section transversale de fleuve par satellite basé sur des mégadonnées, un procédé de calcul de niveau d’eau en temps réel couplé à des informations multi-satellites et un procédé de calcul et de compilation de débit. La présente invention permet de résoudre les problèmes posés par la difficulté des contrôles ou par la mesure en continu du débit de fleuves dans des zones dépeuplées, et d’obtenir un procédé de contrôle de débit par satellite basé sur le principe de la dynamique des fleuves, qui améliore considérablement la plage et la densité des contrôles de débit de fleuve.
