| Sumario: | This degree work aims to determine the temporal variability of evapotranspiration from
images obtained from MODIS sensor, in the Sucio river basin (Chocó and Antioquia); For
this, the historical evapotranspiration (ET) series collected from Terra and Aqua satellites
were used, in a time window from 2001 to 2019 with a temporal resolution of 8 days for the
variables "Total ET" and "Total Potential ET". A temporal time series was changed to a
discrete time series, then a temporal characterization of evapotranspiration was carried out
in a diurnal and monthly cycle, with the results obtained a statistical analysis was carried
out where the main variable was the average. Among the main results is that for the Sucio
river basin, the average monthly evaporation (ET) between the years 2001 and 2019 is 77
mm while the potential evapotranspiration (ETp) is 97 mm. In conclusion, it can be said that
remote sensors allow a calculation of evapotranspiration to be carried out at the regional
level in this way they serve as support to determine the amounts of water necessary in the
irrigation of crops and contribute to the development of models that allow controlling natural
phenomena such as floods. |
