Remote sensing based estimation of actual Evapotranspiration time series for rainfall-runoff modeling at an agricultural river basin of the Brazilian Central Plateau region.

This study aims to assess the application of an Actual Evapotranspiration - ETa time series, estimated from remote sensing dataset, with rainfall-runoff modeling for water production at an agricultural river basin of the Brazilian Central Plateau region. To achieve this goal, the study proposes the development of an ETa time series, using the Operational Simplified Surface Energy Balance - SSEBop algorithm, to apply with stream flow simulations from the Soil and Water Assessment Tool - SWAT, at the Queimado river basin - QRB. The analysis initially makes an evaluation of SSEBop's potential to provide ETa time series in the study area comparing results with field data collected at irrigated agricultural fields. The following step evaluates how the ETa time series generated with SSEBop can improve SWAT's streamflow and water balance simulation, seeking alternatives for ungauged river basins in tropical regions. Further investigations are still recommended to better comprehend the use of ETa time series remote sensing datasets along with calibration tools for rainfall run-off modeling in Central Brazil's watersheds.
