%X This study presents an analysis of the spatial variation of water level by observing the variability of hydro-climatic droughts events in Branco river, since the recurrence of these events has gained great notoriety in recent years due to changes in the landscape and their effects on society. The work is concentrated in 2006 (normal dry), 2015 and 2016 (extreme drought events) over 40 km from Branco river opposite to the city of Boa Vista. The data used are from the hydrological stations of the National Water Agency - ANA and the Center for Environmental Hydrology and Geochemistry of the Amazon Basin Geodynamics - ORE / HYBAM. Identifying the critical years by analyzed the spatial variation of the wet area through remote sensing techniques using images of LANDST 8. There was a reduction of accumulated rainfall in the last 3 years in Boa Vista station, an increase of 185 % for fire outbreaks in relation to 2015 for the entire state and, three discharge records in 2015 and 2016, with a reduction of 41.6% (23.786 km2) of the wet area in 2016 compared to a normal discharge year.
