It is known that vegetation needs a certain amount of water to grow and develop. However, it can be difficult to know the actual water requirement of a specific crop. To quantify the hydric balance in hydrographic basins, detailed knowledge of the components of the hydrological cycle is necessary, especially regarding evapotranspiration (ET). Knowledge of ET of crops and forests, in general, is important at all stages of production management of the vegetation cover. Many studies have been developed with the aim of obtaining these values spatially, but temporal variability remains largely uncertain. Thus, the present study had the objective of utilizing a hybrid Two-Source Energy Balance (TSEB), adjusted to integrate hourly, monthly and yearly ET data, aiming at obtaining ET for two years of study, for areas with sugar cane, planted forest and native forest. How evapotranspiration behaves temporally could then be evaluated. Therefore, after analyzing monthly, seasonal and annual results it could be concluded that sugar cane consumes less water than planted forest and native forest with the same rainfall and environment for all uses.
