VERGARA-LEYES, Oscar Abel et al. Estimación del volumen pluvial captado por cubiertas usando Vehículos Aéreos No Tripulados (VANT): estudio de caso. Tecnología en Marcha [online]. 2024, vol.37, n.2, pp.121-133. ISSN 0379-3982.  http://dx.doi.org/10.18845/tm.v37i2.6708.

In recent years, Unmanned Aerial Vehicles (UAVs) have presented a variety of applications. Recent studies show their advantages when quantifying areas for storm runoff estimation. However, there are uncertainties about their actual range. Therefore, the objective of this study was to estimate the volume of rainfall captured by roofs using UAVs. The methodology consisted of selecting a study area composed of a variety of canopies, in which the areas were digitally measured, the latter by processing images captured by UAV. For the calculation of runoff volume, the average monthly precipitation data of the last 11 years were taken, and the Runoff Coefficients (Ce) reported in the literature were considered. Then, the mean monthly runoff volume was calculated for each canopy. The results show that the roofs studied (Coliseum - Library) have the capacity to capture an annual volume of 2237.75 m3. With an average volume of 406.74 m3 during the rainy season (November to March) and 29.15 m3 during the dry season (April to October). Although the use of UAV allows determining one of the values within the runoff volume calculation, in order to achieve a more accurate result, it is necessary to analyze and evaluate the other variables (Ce and precipitation).
