  abstract = {{T}he study of small reservoirs with low suspended sediment concentration ({CSS}) is still a challenge for remote sensing. {I}n this work we estimate {CSS} from the optical properties of water and orbital imagery. {C}ampaigns were carried out at selected dates according to the calendar of sensor passages, rainfall seasonality and hydrograph of the reservoir for the collection of surface water samples and field spectroradiometry. {T}he calibration between {CSS} and spectral behavior generated {CSS} estimation models from {MODIS} and {L}andsat 8 data, allowing investigation of their temporal and spatial behavior. {T}he {MODIS} model generated a time series of {CSS} from 2000 to 2017, presenting {R}-2 = 0.8105 and {RMSE}% = 39.91%. {T}he {L}andsat 8 model allowed the spatial analysis of {CSS}, with {R}-2 = 0.8352 and {RMSE}% = 15.12%. {T}he combination of the proposed models allowed the temporal and spatial analysis of the {CSS} and its relationships with the rainfall regime and the quota variation of the {D}escoberto reservoir ({DF}). {T}he results showed that the use of orbital data complements the {CSS} information obtained by the traditional methods of collecting and analyzing water quality in low {CSS} reservoirs.},
