INTEGRAÇÃO DE SENSORIAMENTO REMOTO E MODELOS HIDROLÓGICOS PARA A ESTIMATIVA DA EVAPOTRANSPIRAÇÃO: UMA REVISÃO BIBLIOGRÁFICA.

Abstract

The aim of Geographical hydrology is the elucidation of the spatial patterns of water in the terrestrial phase. Different technological tools have been used in recent years to monitor and simulate terrestrial water dynamics and distribution, with emphasis on remote sensing and hydrological modelling techniques. This article presents a review on the use of these technological tools in the study of evapotranspiration, a key variable in geographical analysis. The results points to the benefits of using estimations of remotely sensed evapotranspiration to reduce uncertainty in hydrological modelling simulations, and the possibility of improving assimilation techniques.
