Resumo
Satellite remote sensing systems are widely used in
environmental studies for providing regional scale analyses
with high temporal resolution. On the other hand, when local
small scale spatial studies based on very high resolution data at
specific moments are involved, unmanned aerial vehicles have
been alternatively adopted. The present case study aimed to carry
out the morphometric analysis and quantify the soil loss in two
sinkholes located in Oxisol on carbonate rocks of the Paranoá
Group, in an agricultural area of Niquelândia, Goiás state,
Brazil, using unmanned aerial vehicle, in two periods. From the
analyzed satellite images, it was estimated that the emergence
period of the sinkholes was between December 2018 and April
2019. Based on the aerial survey carried out, 35.53 m² of eroded
area and 236.89 metric tons of soil loss were observed for the
sinkhole 1, as well 299.96 m² of area and 663.47 metric tons of
loss in the first period and 961.66 m² of area and 4,241.68 metric
tons of loss after six months for the sinkhole 2.
