CHARACTERIZATION OF THE HYDROLOGICAL REGIME OF THE JUTAÍ RIVER BASIN WITH THE APPLICATION OF SPATIAL ALTIMETRY

Abstract

Altimetry presents the ability to enter regions of difficult access and monitor variations in height of continental waters. A clear advantage is providing data where traditional measures are lacking. In this, an evaluation of the data set of the Jason-2, Jason-3 and Jason CS-Sentinel 6 satellites was carried out, presented for the 15 years analyzed in the Jutaí River. With a set of 5 virtual stations, variability in water height could be observed, reflecting clarity of variations rather than measurement limitations. The hydrological regime is characterized by being a period of multimodal flooding, rapid rise and slow recession. The dry period occurred during the months of October to February, and the flood occurred during May to July. The results acquired from altimetry demonstrated success in monitoring transient floods in this river on a continental scale.
